VALVE - CHECK 5 PSI (Mitsubishi MB1049867)

A worn check valve can disrupt system pressure and cause erratic operation. This aftermarket replacement part references Mitsubishi catalog number MB1049867. The valve type is a check valve, which allows flow in one direction only. Its plain mechanical function is to open at a set pressure threshold and close to prevent reverse flow. A generic failure consequence is that a stuck-open check valve can allow backflow, leading to pressure loss and component damage. Keeping a check valve in sound condition helps maintain consistent system response. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.204 pounds.
