Overview of pneumatic o-type cut-off ball valve

Pneumatic o-type cut-off ball valve is widely used in natural gas, oil, chemical, metallurgy, papermaking, mining, printing and dyeing, biological pharmaceutical, daily chemical, food and beverage, water treatment and air treatment and other industries of automatic control or regulation control of the fluid, and automatic pneumatic instruments supporting the use. The floating ball valve adopts the structure design of lip type elastic sealing ring to ensure the reliability of sealing for low-pressure, ultra-low pressure or vacuum working conditions. The valve seat sealing structure loaded by plate spring can ensure the long-term reliable sealing of the ball valve. Medium and high temperature ball valve seat material can be selected counterpoint polystyrene or metal material. Fixed ball valve according to the size of the pressure, the nature of the medium and the different sealing requirements and the choice of ball before the sealing structure, ball after the sealing structure or before and after the double sealing structure. The valve seat material of medium and high temperature ball valve can choose counterposition polystyrene or metal material.
