What it does:

The pressure relief valve provides protection against excessive pressure within the pressure washer system. If system pressure rises beyond the valve's preset adjustment, the valve opens to relieve pressure and help protect the pump, hose, fittings, valves, and other high-pressure components.

Pressure Relief Valve vs. Unloader:

A pressure relief valve should not be confused with an unloader valve. The unloader manages normal operating pressure and bypass operation. The pressure relief valve serves as an additional safety device if system pressure rises beyond the intended operating range.

Why it matters:

Excessive system pressure can contribute to:

• Burst high-pressure hoses

• Damaged fittings and valves

• Pump damage

• Seal and packing failure

• Equipment downtime

• Unsafe operating conditions

A properly selected and adjusted pressure relief valve provides an important additional layer of protection for your pressure washer system.

The Giant Pumps Red Spring Pressure Relief Valve is an excellent choice for systems requiring a 3/8" MPT connection, up to 10 GPM, and an adjustable 1200–2400 PSI pressure range.
