Structure features:
Swing check valves within the adoption of the rocker arm swing structure, all the opening and closing of the valve is mounted on the body, not through the body, in addition to the flange parts with sealing gasket and seal ring, the whole not funnelled outside, put an end to the valve leakage.
Swing check valve rocker arm and the disc joint adopts spherical connection structure, make the disc in 360 c range with a certain degree of freedom, trace position with proper compensation.
Scope of application:
Double disc wafer of a swing check valve is suitable for the nominal pressure PN10 ~ PN420, Class150 ~ Class2500; Nominal diameter DN15 ~ DN1200, NPS1/2 ~ 48; Working temperature 196~540 centigrade degree of various pipelines, used to prevent the backflow medium. By choosing different capable person, wafer check valves can be used in petrochemical, metallurgical, power, light industry, food industry such as gray water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea, and other media.
