This valve is pilot-to-close check valve. When pressure at port 1 exceeds the spring bias pressure, the free flow is allowed from port 1 to port 2 and blocks the reverse flow. When the pilot ratio is 1.8:1, meaning that the pilot pressure at port 3 exceeds 1/1.8 (approximately 55.6%) of the pressure at port 1, the pilot piston operates and holds the poppet on the valve seat, thus blocking the flow from port 1 to port 2. The valve can be used in regeneration circuits.

  • The valve allows free flow from port 1 to port 2 and blocks flow from port 2 to port 1 for holding a load. Flow will not be allowed from port 2 to port 1 when pressure is applied to port 3. Nominal pilot ratio is 1.8:1. This means that a pressure of 100 bar (1400 psi) at the pilot port (port 3) will close a valve against a pressure of 180 bar (2600 psi) at port 1.
  • Internal components are made of highquality materials, processed heat treatment and precision grinding to achieve excellent wear resistance and protection against contamination for long-lasting durability.
  • This valve does not permit the flow from port 2 to port 1 under any circumstances.
  • The valve will close when all ports reach the same pressure.
  • The pressure at port 2 affects the pilot-to-close pressure at port 3 in a 1:1 ratio.
  • External components are WINNERcoat® Zinc-Nickel Plating for 1000 hours salt spray test according to DIN EN ISO 9227. Also, some ordering code with letter "P" at the end is stainless steel external components. The ordering code with letter "S" at the end is all components of cartridge valve are made of stainless steel for special requirements such as deep sea, marine or water based hydraulic.
  • Winner guarantees that all products performance a 100% functional test before shipment.
