The structure of the two-seat valve

Anti-erosion poor. Valve flow path complex, high differential pressure applications, more serious erosion by high-pressure fluid, and when the pressure differential caused by the fluid steam and air, adding to the erosion of the valve body seat valve does not apply high differential pressure applications place. Due to the complexity of the flow path, it does not apply to the control of the fiber-containing medium and high viscosity fluids.shut off solenoid valve
Balanced sleeve valve can eliminate most of the static unbalance force, the advantages of the double seat valve has obvious shortcomings of its large leakage is more apparent in the industrial process control, the original two-seater valve occasions, can be used with a balanced structure, the sleeve valve replaced by foreign manufacturers overall structure of the two-seater through the valve to reduce the amount of leakage products.3 way air valve
