VAAS BALL VALVES


VAAS AUTOMATION PVT LTD – A Subsidiary of Bray Controls India Pvt Ltd.

We are pleased to inform that Vaas automation (the leaders in Knife Gate Valves & Ball Valves) is now a 100% subsidiary of Bray Controls India Pvt Ltd -the second largest Butterfly valve manufacturing company in the world..

The most vital ingredient in a VAAS valve is the determination to maintain the highest quality, consistently. The manufacturing facility, located in Chennai is equipped with modern machinery and a team of highly skilled engineers and technicians. Most of the manufacturing is done in-house in the 2200 sq.m factory area, including critical operations such as gate grinding, machining of body and assembly and testing, to ensure consistent quality. The entire operation is linked to a quality assurance system offering high traceability and an ERP system to ensure operational efficiency. VAAS is an ISO-9001:2000 certified company with other approvals such as CE/PED approval, GOST approval for some of its specific product ranges. Whether you require stand-alone Manual valves, or Custom-Painted, Fail-Safe, Actuated packages fitted with Purge Ports, Sensors, Solenoids and Manual Override's, our Engineering experience and vast stock range can satisfy your requirements in a timely and cost-effective manner.

Knife gate valve is one of the application-specific designs among industrial valves. These valves are designed to handle basically non-clean media with features that ensures minimum contact between moving parts of the valve. This is achieved by having a precision-ground gate that is held between layers of gland packing with almost no contact between the body parts and gate during most of its travel.

Uni-Directional Knife gate valve is one of the application-specific designs among industrial valves. These valves are designed to handle basically non-clean media with features that ensures minimum contact between moving parts of the valve. This is achieved by having a precision-ground gate that is held between layers of gland packing with almost no contact between the body parts and gate during most of its travel. The seating itself is accomplished with an almost non-sliding motion aided by jams located in the body. Avoiding sliding contact between gate and body permits this valve to handle abrasive particles present in the media much better than conventional designs. Another feature is the beveled bottom edge of the gate (from which it derives the'knife' in its name) which allows positive closure of the gate even when solid particles settled at the bottom of the body. Knife gate valves are excellent hopper isolation valves with their ability to cut through flowing powders and close by dislodging any material in the seating area. This is also perhaps the only valve design which can tolerate differential thermal expansion of its parts without affecting its functions, thus making an ideal choice for handling high temperature media.

Bi-Directional Knife gate valves are generally uni-directional valves; however, in some application situations, valves are required to handle pressure or flow from either directions. Bi-directional designs are used in such situations. VAAS offers a range of bi-directional gate valves for such requirements. Unlike uni-directional knife gate valves, bi-directional valves are always resilient seated; VAAS offers a design that uses a U-shaped elastomer seal that provides a peripheral seal along the edge of the gate. There is no raised seat in the flow path and in the open position these valves offer maximum flow area and minimum resistance to flow (and lowest pressure drop).

VAAS Ball Valves are available in 8- 350mm, 1-Piece, 2-Piece and 3-Piece designs. Screwed, Welded, Flanged or a mixture in Carbon steel, Stainless steel, and Special Alloys to your order specification. Options include: Fire-safe to API 607, Oxygen Service, Chlorine Service, 3-way Diverters, High Pressure valves (Class 2500), Tank Bottom Valves, V-Port Control Valves, Cryogenic Valves and valves for High Vacuum services in a variety of exotic and standard materials.

Actuation : Vaas manufactures an extensive range of pneumatic cylinder actuators for linear valve actuation requirements. Primarily designed for use with Vaas knife gate valves. These can be used for other linear actuation requirements also. Vaas pneumatic cylinder is a double acting design and is available in a wide range of cylinder diameters and stroke lengths.
