This valve is a check valve used as blocking or load holding device. It allows free flow from port 2 to port 1 and blocks reverse flow.

  • This valve serves primarily to prevent the unintended movement or creeping of loaded cylinders, and it can also be used to close off specific sections within the system.
  • 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.
  • A variety of cracking springs are available for different back pressure application.
  • The seal piston check valve features a fully guided poppet, providing enhanced stability and precise alignment within the valve mechanism.
  • Optimize the movement and positioning of the check components within a check valve to contribute to improved performance, durability, and reliability, ensuring smooth operation and proper alignment of the check component during opening and closing cycles.
  • Industry common cavity.
  • Note: Although 2-port check valves can share the same cavity when they have the same frame size, please pay attention to the mounting direction when installing the valve, otherwise the flow may go in the wrong direction.
  • 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.
