Piston check valve V2050

pilot-operated

The Hy-Pro range of inline pilot operated check valves lock and prevent movement in a cylinder until oil pressure is applied to the pilot piston. Manufactured in three flow rates, 27, 40 and 60 litres per minute these valves are located between the control valve and actuator to lock the system. Hy-Pro check valves are manufactured using hardened components and toughened seats to provide a positive lock and extended service. The precision ground piston has a generous pilot ratio to ensure ease of unlocking. Used to lock cylinders to prevent movement. The Hy-Pro check valve can be used with single or double acting cylinders. However, when lowering a single acting cylinder a pilot flow must be provided to unlock the check valve.
