Hydraulic check valve performance characteristics

Daily operation of the hydraulic check valve performance characteristics are as follows: 1, the hydraulic check valve fluid resistance small, hydraulic check valve are all valve minimum fluid resistance among the class a, even reducing hydraulic check valve, the fluid resistance is small. 2, hydraulic check valve passage level off is smooth, not easy to deposit medium, can undertake pipeline hydraulic check valve. 3, hydraulic check valve switch, convenient quickly, as long as the valve rod rotation 90 °, the hydraulic check valve is completed fully open or close the action, it is easy to realize rapid opening and closing. 4, hydraulic check valve opening and closing, do turn 90 °, so easy to achieve automatic control and remote control, hydraulic check valve can be configured pneumatic device, electric actuator, hydraulic device, gas liquid linkage or electro-hydraulic linkage. 5, hydraulic check valve sealing performance is good. Hydraulic sewage check valve seat sealing generally use the elastic materials such as teflon, easy to guarantee the seal, and the hydraulic check valve sealing force with medium pressure increases. 6, reliable hydraulic check valve stem seal. Hydraulic check valve opening and closing the valve stem make rotation movement only, so the valve stem packing seal is not easy to be destroyed, and stem pour sealing sealing force with medium pressure increases.
