Product Overview

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.

Key Features

  • Subplate connection
  • Leakage-free closure in one direction

Industrial Applications

  • The check valve RVP 20 is mainly used at the outlet of the pump as a back pressure valve and bypass valve.
  • 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.

  • The fluid must be filtered. Minimum filter fineness is 20 ㎛.
  • The tank must be sealing up and an air filter must be installed on air entrance.
  • Products without subplate when leaving factory, if need them, please ordering specially.
  • Valve fixing screws must be high intensity level (class 10.9). Please select and use them according to the parameter listed in the sample book.
  • Roughness of surface linked with the valve is required to 0.8.
  • Surface finish of mating piece is required to 0.01/100mm.
