W Series
Whether an application is referred to as “severe service”, “high performance”, or “heavy duty”, we have overcome the corresponding challenges with our Wey design. We pushed it to the limit, and the result is the W series. It offers the greatest flexibility, including for the range of nominal sizes, materials, and pressures. It opens up an incredible scope of application. With the W series, we guarantee that we will outperform the competition, no matter what the situation.

Face to face dimension

The robust universal bonnet can be used for a wide variety of actuator types. Many different add-on parts can be easily fitted.

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.

In the closed end position, the gate is also mechanically supported.

With its optimized gate geometry, accumulated media is pushed out of the gate guide and flushed out into the bore by the increased flow.

The flange threads make assembly considerably easier, while also allowing for dead-end installation.
