VG Series
Wey VG knife gate valves are products with a special flange. They were specifically developed for biogas applications in agriculture, since standard DIN gate valves for industrial pipelines are not compatible. The VG is available exclusively in cast iron, and only in the nominal sizes DN 150 and DN 200.

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.
With its optimized gate geometry, accumulated media is pushed out of the gate guide and flushed out into the bore by the increased flow.
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.
A mechanically retained round cord seal creates a bubble-tight shut off on the gate edge.
The gate is mechanically guided over the full stroke.
The gate is mechanically guided over the full stroke.
