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. 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.
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.
