Alutal Measure & Trust


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. However, it offers our customers the highest level of reliability and durability in use. This is also because – like all Wey products – it can be repackaged at any time and guarantees zero leakage during use.

The robust metal yoke enables the optimum and simple installation of mechanical or inductive limit switches. The yoke can be removed on one side. This facilitates access to the mechanical parts.

With its optimised gate geometry, accumulated media are pushed out of the gate guide and released into the bore by the increased flow.

A mechanically retained round bead seal creates a bubble-tight closure at the gate edge.

A unique transverse seal consisting of a transverse sealing profile and sealing compound makes the body bubble-tight towards the atmosphere.
