Product Overview

Established through a strategic partnership between the Chinese and German governments in 1979, Huade cooperated with Rexroth twice. Huade® check valve Z2S 16 can replace Rexroth’s Z2S 16 in the same series. The price is more reasonable.The factory has a good inspection system to ensure stable performance. Each Z2S 16 will be packed in standard cartons and waterproof plastic packaging before leaving the factory. Huade has passed ISO9001, ISO14001, and OH SAS18001. Huade® hydraulic directional valves are used in the military industry due to reliable performance. It is an old national brand in China.

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 check Valve Z2S is used for vertical stacking installation. It can seal one or two working oil ports without leakage as needed.
  • Pilot operated check valve type Z2S 16 is sandwich plate design. It is 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 is pressured and is pushed to the right, thereby opening the ball poppet valve which then opens the poppet. 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.
