3 Piece Trunnion Ball Valve

Short Description:

3 Piece trunnion ball valves are designed, engineered and manufactured especially for oil and gas pipeline application.

Key Specifications / Features

Relia trunnion ball valve design allows for reduction in valve torque as the ball is supported in two places
design ball valves incorporate the use of upper and lower supports ( trunnion plate system) to retain the ball under pressure.

Trunnion plate system feature is standard on all Relia API 6D trunnion ball valves from 2” and up (ANSI 150 through 2500). It permits the valve to be installed in either direction, since the trunnion prevents the ball from shifting — or worse, blowing out – under high pressure applications.
One of the benefit of the Relia trunnion plate system design is that it allows the ball to only rotate a quarter turn with no hysteresis thus more control and reliability under extreme applications.

3 Piece trunnion ball valves are side entry with bolted body construction. 3 Piece trunnion ball valves are designed, engineered and manufactured especially for oil and gas pipeline application. Relia Trunnion Ball Valves provide excellent corrosion resistance and superior sealing performance at both high and low pressures.

Features of SPE & DPE Seat Design are available upon request. The material will meet NACE MR0175 as client request.
