Scorpio 3X

Triple Offset High Performance Butterfly Valve

The Westad Scorpio is designed for full shut-off and throttling services.

After 100 years of valve manufacturing, Westad has designed a valve for special applications that will perform under extreme conditions.

The main design focus has been to minimize maintenance. No special tools are required, to reduce the operational cost.

A wide range of materials are available to suit different service requirements and all bearings, gaskets and packings are made from non-corrosive materials.
