Product Description


Reduce Port API6D Flanged Stainless/Carbon Steel Trunnion Mounted Ball Valve with Worm Gear

Reduce Port Trunnion Mounted Ball Valve use reduce port to adjust fluid medium flow, compared to full port type, reduce port trunnion mounted ball valve does not have high requirements for fluid flow. Reduce port trunnion mounted ball valve has low torque, and it is double seat sealing, there is no limit for fluid flow direction, both sides could have good sealing function. Trunnion mounted ball valve is suitable for high pressure and bigger size pipelines.

Trunnion mounted ball valve use trunnion ball which could bear much higher pressure. There is a trunnion in the bottom of valve body connected with ball and stem, when rotate stem, ball will round from 0 to 90 degree. Trunnion mounted ball valve has grease injection valve and Vent Valve for clean and release medium. API6D trunnion mounted ball valve has fire safe and anti-static device design to protect.
