Relia is a trunnioin ball valve manufacturer and supplier with API 6D, CE, and API 607 certificates.
Trunnion ball valves are our featured products, with double block and bleed, or DIB. Trunnion ball valves are available in side entry or top entry, with a soft or metal seat.
The trunnion ball valve is a form of quarter-turn valve that uses a solid, perforated, and fixed/supported ball to control the flow through it. The line pressure drives the upstream seat against the stationary ball, so that the line pressure forces the upstream seat onto the ball, causing it to seal.
The advantages of trunnion ball valve design are lower operating torque, ease of operation, minimized seat wear, and superior sealing performance at both high and low pressure.
The trunnion ball valve is available for all sizes and all pressure ratings for shutting off service.
