Quantity in stock: 0
Description The RVCV56-20X is a screw-in, cartridge, direct acting poppet relief valve with reverse flow check valve. Operation This device is intended for use as a pressure limiter and regulator in demanding hydraulic circuits which require fast response, low hysteresis, low leakage, low pressure override, and reverse free flow features. The RVCV56-20X blocks flow from port 1 to port 2 until sufficient pressure at port 1 will displace poppet from the seat. Relief flow discharges to port 2. Reverse flow occurs from port 2 to port 1 when differential pressure between port 2 and port 1 exceed check spring value. Features Maximum pressure 420.6 bar (6100 psi) at port 1. Adjustments cannot be backed out of the valve. Adjustments prohibit springs from going solid. Hardened spool and cage for long life. Fast, smooth response to pressure surges.
