Trunnion Mounted Ball Valve
Trunnion mounted ball valve is specially designed for fluid flow control in piping system under high working pressure. The precision of the ball position is highly guaranteed at high pressure, providing an excellent operation performance. The valve seat is designed with seat springs to push the seat against the ball, ensuring a tight bi-directional sealing performance. The valve body is manufactured through forging or casting process.
- Nominal size: NPS 1/2"-NPS 60" (DN15-DN1500)
- Pressure: CL150-CL2500 (PN10-PN420)
- Temperature range: -196°C to 550°C
- Valve operation: manual, bevel gear, pneumatic, electric, pneumatic-hydraulic, electro-hydraulic, etc.
- Double Block & Bleed: coupled with spring preloaded floating seats, valve seats independently shut off the fluid on the upstream and downstream at the side of the ball whether the valve is fully opened or closed, the residue in the body cavity will be removed through the drain.
- Pressure Self-relieving: the self-relieving seats are capable of automatic relieving of excessive pressure that is built up inside the body cavity, eliminating the need for installation of a pressure relief valve. Self-relieving function plays a critical role in safe transferring of liquid fluids.
