Cast Steel Trunnion Ball Valve is also called fixed ball valve, the ball inside is fixed at the top and the bottom. It has been designed two piece body or three piece body type and with two floating seats, which are moveable under the pressure of medium. It is widely used in the industries of natural gas, oil products, chemicals, metallurgy, environmental protection and pharmaceuticals, etc.
The 2-piece Trunnion Ball Valve with PTFE Seat is designed for applications where reliability, durability, and precise control are essential. This valve features a trunnion-mounted ball that provides superior support and stability, making it ideal for high-pressure and high-temperature applications. The PTFE seat ensures excellent chemical resistance and low friction, enhancing valve performance and extending its lifespan. The two-piece construction allows for easy assembly and disassembly, making maintenance straightforward and cost-effective.
