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.
Complexity in every detail
At the request of our customer, these pneumatically operated knife gate valves VS were equipped with numerous specific attachments. The stainless steel valves are thus perfectly matched in every respect to their subsequent place of use in the plastics processing industry.
System changeover to knife gate valves
These knife gate valves VM DN 4″ were recently installed at a wastewater treatment plant in Ohio, USA. The existing scum system was aging and pumps and valves needed to be replaced. Our Wey knife gate valves were selected due to their resistance to deposition and solids. Compared to the previously installed plug valves, they are also much lighter and therefore easier to handle. The system was commissioned successfully in October.
Abrasion protection in paper production
It’s not just the unusual color that catches the eye with this knife gate valve. The valve is equipped with various options to withstand demanding applications in the paper industry.
