The mechanical check valve consists of two opposing checks with two mechanically actuated poppets at port 1 and through port. Typically, this valve is installed at the piston of a cylinder. When the cylinder reaches the end of its stroke, the poppet will be lifted from its seat, allowing the flow to pass the poppet. By this way, dual cylinders can achieve synchronization in either or both directions at the same position before the end of the stroke.

  • The machining cavity of this valve must be aligned with the movement of the mechanical structure and perpendicular to the contact surface. For example, when installed in a hydraulic cylinder piston, the maximum allowable offset is 5° to ensure the valve's long life. (The valve strength is not designed to handle radial forces.)
  • Note: This valve is not designed for cam application.
  • Do not use this valve to be a mechanical stop.
  • Note: Do not use port 2 of this valve.
  • The cavity 162A-2 is not available to this valve. Please refer to cavity 162AP-2.
  • The maximum stroke must be less than 1.2 mm when a mechanical stop reaches the poppet, otherwise the internal components will be damaged.
  • A mechanical check valve in the piston can eliminate extra fluid or compensate for lack of fluid when the cylinder has completed its stroke. To avoid unnecessary force on the gland.
  • A mechanical check valve is a good option to balance the pressure in the cylinder and it is able to eliminate or compensate fluid during cylinder operation.
  • In the vertical cylinder mounting application, a mechanical check valve can bleed air at the end of the stroke.
  • Synchronizing the master/slave cylinder pistons with mechanical check valves ensures that the cylinders reach the same position at the end of their travel in both directions, making it wellsuited for dual cylinder steering applications.
  • This valve offers very low leakage, with a maximum leakage of approximately 0.07 cc/min (1 drop/min) at 350 bar.
  • 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.
