Neles Series XH Trunnion Mounted Ball Valve

Brand: Valmet

Metso has designed this ball valve to mount on two large, low-friction trunnion bearings, with the spring-loaded seat in continuous contact with the ball surface. 

The trunnion mounted XH valve can be used for high cycle shut-off and throttling service with high pressure differentials.
