The Suttner Pressure Relief Valve 900000069 is a safety-critical component designed to protect pressure washer systems from damage due to extreme pressure spikes. Often referred to as a “pop-off” valve, it is engineered for 1000 to 4000 PSI systems and supports flow rates up to 6 GPM.
Constructed from durable brass with a soft seat design, this valve helps eliminate leakage (“weeping”) while delivering consistent safety performance. It is adjustable in the field for operational flexibility and features end discharge for easy system integration.
The valve uses a 3/8\\” MPT inlet, making it compatible with most commercial and industrial pressure washer configurations.
