The main business of Huafilter is hydraulic system repair and export of Huade® hydraulic products. We are the only one overseas distribution company of Beijing Huade Hydraulic Industrial Group in 2023. Huade® check valve RVP 20 has incorporated cutting-edge technology from Rexroth. It is more durable than the similar products in this line. We provide a good after-sales service, with experienced engineers providing timely technical support. We are committed to collaborating with enterprises worldwide for mutual success.
Cooperation with Rexroth for the second time in 1995, Huade’s high performance check valve RVP 20 can completely replace the same type valve offered by Rexroth. The price is more reasonable. All Huade® check valve RVP 20 have one year warranty. The factory has passed ISO9001, ISO14001, and ISO45001. Huade® check valves are widely used in engineering and construction machinery, metallurgy, machine tools, etc. This is an old brand in China.

Production Details of the Check Valve RVP 20
The check valve type RVP 20 has the task of, preferably closing a flow leak free in one direction and to permit free flow in the opposite direction. The structure diagram is as follows. It basically comprises of the housing (1), poppet (2) compression spring (3),and spring seat(4). The stroke of the poppet (2), which is guided on its outside diameter,is limited by a mechanical stop. The built-in compression spring (3) supports the closing movement. Furthermore the compression spring(3) holds the poppet (2) in the closed position even when there is no flow through the valve.
