Industrial hydraulic S type check valve NPTF 315Bar 600L/min NG6-10 G thread/SAE C.S/SS
Check valve type S is used to allow fluid flowing in one direction and leakage-free closure in the
opposite direction. When fluid flow via port P1, fluid pushes poppet (2) to move overcoming the
spring(3), and connects chamber P1 and P2. When fluid flows from P2 to P1, poppet (2) moves left
and the check valve closes.
For check valves without a spring, the fixed position should ensure that the poppet will remain at the
closed position.
