Safety Relief Valve 4500 PSI
The Mi-T-M 22-0309 is a brass safety relief valve designed for pressure washer systems. It protects pumps and components by venting excess pressure during operation. This part suits owners and technicians maintaining compatible Mi-T-M equipment.
Pressure Capacity and Headroom
The valve is rated to open at 4500 PSI, providing a pressure ceiling for high-output machines. It handles normal pressure spikes within that range without venting. Sustained overpressure beyond the set point will cause continuous discharge.
Thread and Installation Limits
The valve uses a 1/2 inch connection for direct mounting into the pump or manifold. Brass construction resists corrosion from water and detergents. Correct thread engagement and torque are required to prevent leaks at the seal.

Questions about this item
Will the 1/2 inch brass safety relief valve thread into the existing pump housing on my older Mi-T-M pressure washer?
The valve uses a standard 1/2 inch connection and brass construction compatible with Mi-T-M pumps designed for this fitting size.
How can I confirm the 4500 PSI relief valve is activating at the correct pressure after installation?
The valve should discharge water when system pressure reaches the rated 4500 PSI limit during operation.
Does the box include the hose barb fitting or must I purchase the HB connection separately?
The HB designation indicates the hose barb is supplied with the 22-0309 safety relief valve assembly.
