Product Overview

Huade has incorporated cutting-edge technology from Rexroth due to seven years of experience in cooperating with Rexroth from 1979. Check valve Z2S 10 from Huade is an affordable alternative to the same series from Rexroth. Huade has passed  the international standard, namely ISO9001, ISO14001, and OH SAS18001. Each check valve Z2S 10 undergoes rigorous testing before leaving the factory to ensure superior performance. Huade® hydraulic valves are widely used in engineering and construction machinery, metallurgy, machine tools, environmental protection, shipbuilding, aerospace, rail transit, petroleum and petrochemical, military industry and other fields. It is a well-know national brand in China. It is more advanced in technology and more durable than the similar products in this line.

Key Features

  • For use in vertical stacking assemblies
  • For the leak free closure of one or two service ports
  • Porting pattern to Din 24 340 form A, ISO4401 and CETOP - RP 121H

Industrial Applications

  • This pilot operated check Valve Z2S is used for vertical stacking installation. It can seal one or two working oil ports without leakage as needed.
  • Check valves type Z2S 10 are sandwich plate design. They are used for the leak-free closure of one or two service ports, even for long periods of time. Free flow occurs from A1 to A2 or B1 to B2. Flow in A1 B1 the opposite direction is blocked. When fluid flows from A1 to A2, the spool (1) is pressured and is pushed to the right, thereby opening the ball poppet valve (2) which then opens the poppet(3). In order to ensure correct closing of the valve, the A2 B2 service ports of the directional valve must be connected to tank in the neutral position.
