VS series
The appeal of the VS series lies in its ingenious semi-lug design. The lightweight construction of this knife gate valve, which is available in stainless steel, makes it very cost-effective. Nonetheless, it gives our customers the highest level of reliability and durability in use. This is also because – like all Wey products – it can be repacked at any time and ensures zero leakage while in use.

Face to face dimension
-
The robust metal yoke enables the optimal, simple assembly of mechanical or inductive limit switches. The yoke can be removed from one side. This makes it easier to access the mechanical parts.
-
A unique transverse seal, consisting of a transverse seal profile and packing compound, makes the body bubble-tight towards the atmosphere.
-
The transverse seal can be repacked at any time and under full pressure using the lateral packing screws.
-
With its optimized gate geometry, accumulated media is pushed out of the gate guide and flushed out into the bore by the increased flow.
-
In the closed end position, the gate is also mechanically supported.

Triple protection in demanding environments
Sometimes more is simply more. This Wey knife gate valve VSC DN 100 is protected against all types of harmful influences.
-
High requirements in the petrochemical industry
The media transported through the pipelines of petrochemical plants are often highly corrosive and must not be contaminated under any circumstances. We therefore generally use stainlesssteel valves, such as this knife gate valve VS. It is equipped with a special limit switch and solenoid valves that are Ex d flameproof certified as well as with a filter regulator that cleans the compressed air and adjusts the pressure as required. Complete stainless steel tubing provides additional protection against damage and corrosion.
