Hydraulic type RVP check valve 350 bar 600L/min 6-40 sup-plate mounting one-way valve block
Function and configuration
Check valve type RVP is used to allow fluid flowing in one direction and leakage-free closure in opposite direction. When fluid flows via port P1, fluid push poppet(2) to move right way overcoming the spring(3), then connects the chamber P1 and P2. When fluid flows P2 to P1, poppet(2) moves left way and then the check valve closes.
