This valve is a check valve designed to block or hold single-way flow (from port 2 to port 1). These valves are designed to prevent backflow or reverse flow in hydraulic systems, which can cause damage to the system and reduce efficiency.

  • 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 high-quality 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.
  • WINNERcoat® Zinc-Nickel Plating is salt spray tested in accordance with DIN EN ISO 9227 for up to 1000 hours.
  • Winner guarantees that all products performance a 100% functional test before shipment.
