Model:STV-Q347F-150LB-WCB-24″

Under the action of medium pressure, Ansi Cast Steel Ball Valve can produce a certain displacement and press tight on the sealing surface at the outlet end to ensure the sealing of the outlet end. The floating ball valve has a simple structure and good sealing performance, but the load of the ball subjected to the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the spherical medium. This structure is widely used in high and medium pressure ball valves.

It is mainly used in various high-pressure medium conveying pipelines in chemical, metallurgy, petroleum, pharmaceutical and other industries. The applicable temperature is -196~450 °C; driving mode: manual, pneumatic, electric, hydraulic, turbine, etc.; nominal diameter: 1/2″~12″; nominal pressure: 150LB~1500LB; applicable medium: water, gas, oil, natural gas and acid-alkaline corrosion medium.

What is the difference between a trunnion ball valve and floating ball valve?

The ball in a trunnion ball valve is supported by the stem and trunnion, reducing the operating torque, while the seats are spring loaded. In a floating ball valve, the ball floats and the seats are fixed while the ball is only supported by the stem.

How does a trunnion ball valve work?
