NELES™ TRUNNION MOUNTED, BALL VALVES SERIES XH, CLASS 600 Neles has over 50 years experience of trunnion mounted ball valves. Based on this experience we have designed this ball valve to comply with latest product specifications and performance standards. Valve performance complies with ISO 15848 fugitive emissions providing sustainable valve performance. Enhanced reliability and cycle life to meet the industry target extended maintenance interval. The trunnion mounted XH valve can be used for safety, high cycle shut-off and throttling service with high pressure differentials. The modular design incorporates two large, low-friction trunnion bearings, with the spring-loaded seat in continuous contact with the ball surface.
