Ball - Trunnion Mounted - Pipeline

Robert Cort C-B5 Trunnion Mounted Ball Valves (Pipeline)

Manufacturer of pipeline ball valves for a wide range of applications. With a global reputation for high quality, reliability and safety, the Cort C-B5 trunnion mounted pipeline ball valve is available in sizes from 150mm – 1200mm (6” to 48”) and pressure ratings from class 150 to 2500.

The Cort C-B5 Ball Valve uses a three piece, bolted body design manufactured from ring rolled forgings. The cast or forged ball features integral, external trunnions which turn in bearings mounted in bearing retainer blocks. These bearing retainers are precision located between the valve closures which are then able to resist the pressure loading on the ball.
