Thermodynamic Steam Trap
Thermodynamic steam trap with inbuilt strainer and full stainless steel construction, best suited for header and mainline drains and drop legs.

Thermodynamic Steam Trap is suitable for draining main steam distribution lines where prompt removal of condensate is essential. This trap uses the velocity and phase change of pressurised condensate flashing to lower pressure steam to operate the disc. Its hardened seat and disc and absence of moving parts ensures a long service life. Although the trap operates in any position, horizontal orientation is preferred.

Although the trap operates in any position, horizontal orientation is preferred. Integral blowdown valve allows on-line cleaning of strainer screen. During startup, air is trapped in the control chamber of thermodynamic trap. Being air, it cannot condense and hence the pressure will not drop. This causes the trap to fall in closed condition. Our range of thermodynamic traps is specially designed trap to overcome this air binding problem. It is a trap with a 100 mesh stainless steel screen & a special anti-air-binding disc.

We also manufacture maintenance high pressure Thermodynamic Steam Trap with integral strainer designed specifically for steam main drainage applications up to 100 bar g.

This thermodynamic steam trap uses a disc to control the release of condensate and to trap steam. The disc which is the only moving part rises and falls in response to the dynamic forces produced by the partial re-evaporation (flashing) of hot condensate. Cool condensate, air and other, non-condensable gases enter the trap through central orifice, lift the disc and discharge through outlet orifice when the condensate approaches steam temperature a part of it flashes as it enters the trap. The flash steam passes at high velocity over the underside of the disc and collects in the control chamber above the disc. The resulting pressure in balance forces the disc downward on to the seating surfaces, stopping the flow. The trap remains tightly closed until the loss of heat through the trap body lowers the control chamber pressure, allowing the inlet pressure to raise the disc and repeat the cycle.

The trap remains tightly closed until the loss of heat through the trap body lowers the control chamber pressure, allowing the inlet pressure to raise the disc and repeat the cycle.

Inverted Bucket Trap
Inverted Bucket Traps have been popular although in every application, superior results can obtained with float type of steam trap. They consume a small amount of steam during operation but can blow fully open if they lose their prime, due to over sizing or a rapid drop in inlet pressure. Their discharge is intermittent.

OPERATION :
The trap body is normally filled up with condensate to maintain a seal water around the inverted bucket. Live steam enter the bucket, floats it, to close the valve. Steam leaks through a small hole in the top of bucket, and opens the valve to discharge condensate. Some inverted bucket traps are fitted with an auxiliary bimetal air vent.

Advantages:
• Fair resistance to water hammer
• Can be made for very high pressure

Limitations :
• Low thermal efficiency under varying loads and pressures, some steam loss for operation
• Must maintain water seal to avoid continuous discharge of steam
• Must be protected from freezing
• Cannot discharge condensate continuously as rapidly as it forms
• Bleed hole in bucket has very limited air-vent capacity
• Bimetal auxiliary air vent must be factory set at a low temperature – not self-adjusting
• Can result in water logging of steam space

Typical Applications: High Pressure indoor steam main drips & submerged heating coils
We also manufacture cast steel inverted bucket steam trap which is designed for horizontal pipelines. It is maintainable inline and is available in sizes 15 NB, 20 NB and 25 NB.

Our series of cast iron inverted bucket steam traps is designed so that it can be fitted into horizontal pipelines. They are maintainable inline and are complete with integral strainer screen.

Glandless Piston Valve
FM PISTON VALVE is a zero leak isolation Piston Valve, in which the seat & gland are replaced by Lower & Upper Sealing rings along with a Piston. This overcomes the difficulties usually associated with the replacement of conventional seats.
The FM Piston valve is the name for prevention of inline leakage as well as leakage through glands, making for leak-proof isolation in the pipelines.
The FM Piston valve is a seat less & gland less Piston Valve. At the heart of the FM piston valve are Piston & sealing rings. A burnished piston seals against SS reinforced graphite rings to achieve a leak proof shutoff. This unique design ensures a long life even at high temperatures up to 427 deg C
A Burnished piston is connected to the Piston Valve stem & hand wheel. The piston passes through two sealing rings separated by a lantern bush. Each sealing ring is Stainless steel reinforced graphite, which has both features of sustaining compression exerted by Bonnet & providing soft seal against piston. The upper sealing ring acts as a conventional gland packing and prevents leakage towards atmosphere. The lower sealing ring acts as the seat which prevents in line leakage. The lantern bush is required to maintain separation between the upper & lower rings & to allow flow through the Piston Valve.

FEATURES :
Larger effective sealing area :
Leak proof isolation - Class 6 shut off achieved.
Durability - Piston unexposed to media
Absence of Gland & Seat
Maintenance friendly - Uniform sealing rings on both the sides & maintenance can be done without removing the Piston Valve from the pipe line. (On-line Maintenance)
User Friendly - It does not need Piston Valve Key
The Only Scrap Free Piston Valve
Self Lubricating
Self Cleaning

RANGES :

Y-type strainers with stainless steel screens have 0.8 mm diameter perforations as standard.
The strainers are available in wide range of sizes.

Moisture Separator
Moisture in steam blocks heat transfer. In compressed air, it fouls your application. Moisture separators are a simple and effective way to improve both your processes. Installation upstream of pressure reducing valves and steam meters ensures accuracy and a long mechanical life.

Disc Check Valves
Our Check Valves are recommended after traps discharging into closed systems to guarantee against return or spill back. Check valves feature a compact and rugged stainless steel design and are suitable for any process liquid & gas, not just steam. Main advantage of these check valves is they can be mounted between pipe flanges in any direction.
Check Valves are designed to be sandwiched between flanges i.e. wafer type. They are suitable for use on a wide range of fluids for applications in process lines, hot water systems, steam and condensate systems etc.

Diffuser
Our Diffuser is a compact unit designed to be fitted to the outlet of a steam or air trap discharging to atmosphere. The Diffuser reduces the problems of noise and erosion by dampening high velocity discharge. It can be fitted to any trap where conditions promote blast discharge similar to that associated with balanced pressure, inverted bucket or thermodynamic traps.
More than 80% reduction in the sound pressure level can be expected when measured at 1 meter from the discharge point.

Vacuum Breaker
Our vacuum breakers are suitable for general purpose applications such as on condensing vapour (steam) or liquid systems etc.

Float Traps
Float Traps is the best choice for process applications.

The Float Trap from Forbes Marshall is the product of experience. First launched in the 1940's, it has become the most advanced ball float steam trap available. Unique amongst all float steam traps is the self-aligning main valve, water hammer proof float assembly and corrosion resistant air vent Such attention to detail ensures complete shut-off at all pressures and reliable operations which lead to an extended product life and minimal maintenance. Having an integral thermostatic air vent and options of a steam lock release and drain cock tapping, our range is adaptable to all applications where ball float traps are recommended and instantaneous removal of condensate is required.

Automatic Pumping Trap
The Automatic Pumping Trap - the world's smallest condensate drainage system that works under all the load conditions, even vacuum. It's compact design makes it convenient to install within 200 mm of the installation head. The Automatic Pumping Trap is fully mechanical with no requirement for electrical power, pnuematic supply, motors or level switches.

Balanced Pressure Thermostatic Trap
Balanced Pressure Thermostatic Traps have a blast discharge with high air venting capacity. Their valve & seat are wide open when cold.

Operation:
The trap is operated by a thermostatic fluid filled capsule. When steam is turned on, air discharges through the open valve orifice. Cold condensates enter & passes out. At a temperature t below the saturated steam temperature corresponding to the pressure at the trap, the mixture boils & exerts a vapour pressure. While the outside of the capsule is at steam pressure, the inside, because of the temperature head, is at a higher pressure. This excess pressure closes the valve on its seat before steam temperature is reached. Condensate help in the trap, cools by t below steam temperature, until the vapour pressure in the capsule is below the steam pressure. The capsule contracts & the valve opens. Since the curves of the fluid inside the capsule & water are parallel, it does not matter what the steam pressure is in the trap. At any pressure p there will be an unbalanced force p holding the valve shut, after a temperature t below saturated steam temperature is reached. If superheat is present an internal pressure higher than p, is taken up by the flexible diaphragms in the capsule.

These traps are available with an inbuilt flat strainer screen having 0.8 mm diameter perforations. These traps are mainly used on Steam Tracing application. When installed at the end of steam line or process equipment, these traps function as steam trap and when installed on steam line header, it acts as air vent.

We also manufacture maintainable balanced pressure trap designed for small condensate loads usually associated with instrument tracing applications. Manufactured in stainless steel it is corrosion resistant and is easily maintainable.

We also manufacture bimetallic, medium pressure, temperature sensitive, maintainable steam trap. The operating element comprises a stack of bimetal discs which control the flow of condensate at a preset temperature below steam saturation.

Sight Glasses
The sight glass is a novel product that allows you to visualize the flow of steam, water or oil inside pipelines. The visualization of flow helps diagnose problems occurring in equipment upstream or downstream of the sight glass.
It overcomes the problems of poor visibility and improper distinction between vapor and condensate flow by using a deflector plate to separate the vapor and condensate. This new design is ideal for applications in which one wants a clear indication of flow, such as downstream of paper drying cylinders, in DM water lines or monitoring steam traps and heat exchangers.

Temperature Control
Temperature control (Is control of your process temperature important?)
Many types of steam plants need to be fitted with some form of temperature control. In any process, product quality is often dependent upon accurate temperature control, while heating systems need to be thermostatically controlled in rder to maintain optimum comfort conditions. From an energy saving point of view, the ideal temperature is bviously the lowest, which can be accepted for any given application. Our self-actuated temperature controllers control the temperature of the process within an accuracy of +/- 2deg C by controlling the flow of steam.
Our controller is a self operated temperature control for use on steam. By virtue of its pilot operation, it has a comparatively small control brand.

Self Actuating Temperature Controller
The self actuating temperature controller offers cost effective temperature control for steam and water.
Available Sizes and Pipe Connections are :
15, 20 & 25 NB 'SB' valve
40 & 50 NB 'NS' valve.

Small Water Temperature Control
Small Water Temperature Control is for use on water systems, heating or cooling.
The available types are :
- 2 port normally open diaphragm balanced control valve
- 2 port normally closed diaphragm balanced control valve
- 3 port mixing or diverting valve
Self Acting Temperature Control Valve
• No compressed Air needed
• No electricity needed - completely self acting
• Accurate, Reliable, Easy to use & install
• Intrinsically safe, free from electrical/pneumatic breakdown, virtually maintenance free
• Operate between a band of ± 2°C,
• depending on time constants & controlled medium.

Principle of operation :
A change in temperature at sensor will cause the liquid filling inside to expand or contract. The expansion / contraction of the liquid provides the closing / opening force to the 2 port control valve plug. The TR Series is engineered and manufactured for steam systems. It incorporates overheat protection mechanism, double plug and seat design for sizes above 1". It has a standard capillary length of 2 mtrs but options of higher capillary lengths are provided. It is designed with a long enough sensor to ensure accurate sensing (and not localized sensing) and thereby provide better accuracy especially in large tanks, reactors, vessels etc.

Steam Pressure Reducing Valves

Pressure reduction is essential. Reasons for pressure reduction:
• Steam boilers are usually designed to work at high pressures. Working them at lower pressures can result in carry over of water.
• Steam at high pressure has a lower specific volume which means that a greater weight can be carried by a pipe of a given size. We recommend distribution of steam at high pressure and reduction at the point of usage. This reduces capital loss for piping and insulation and also reduces distribution losses.
• Steam pressure may be reduced to save energy. Steam at lower pressures has higher latent heat. Reduced pressure of steam also leads to reduced heat loss and lower flash steam formation from open vents etc.
• Since the pressure and temperature of steam are related, controlling the pressure enables us to control the temperature in the heating process.
• Pressures must be reduced so that they are within the rated safety limits.
• In plants where steam usage takes place at many different pressures, pressure reduction allows generation of steam at a single high pressure and subsequent reduction to the desired pressure at the point of usage
