The Daikin MP-02A-20-55 is a 02 Series modular stacking-type pilot-operated check valve designed for hydraulic circuits where reverse flow must be prevented and pressure maintained in an actuator or hydraulic line. Its modular design mounts directly to a Daikin 02 Series manifold with other stack valves, adding check-valve functionality without separate in-line piping. When pilot pressure is applied, the valve can be opened to permit reverse flow, making it suitable for load-holding applications such as supporting a hydraulic cylinder or helping prevent actuator drift.
The MP-02A-20-55 features a control port on Port A, 0.2 MPa cracking pressure, a maximum flow rate of 40 L/min, maximum operating pressure of 25 MPa, and an Rc 1/4 nominal port size. Because the MP-02 series includes configurations that vary by control port, cracking pressure, and design number, matching the exact MP-02A-20-55 part number is important when replacing a valve to ensure compatibility with the existing stack assembly.
