Description:
The General Pump YU21405 is a high-capacity, green-spring trapped pressure unloader valve designed for demanding industrial pressure washer systems. With a rated flow of 21.0 GPM at 4,050 PSI and a maximum pressure rating of 4,500 PSI, this valve excels in large-scale cleaning rigs, multi-gun systems, or high-volume pump applications.
Manufactured with robust brass construction and stainless-steel internals, the valve features dual inlet and bypass ports to easily integrate into complex systems. The green spring identifies it as a high-flow model in the General Pump lineup.
Ideal for operations needing dependable pressure regulation and system protection, the YU21405 ensures smooth, reliable performance under heavy use.
Key Features:
High-flow capability: 21.0 GPM rating for large systems
Heavy-duty design: Brass body and stainless internals for long life
Dual bypass ports: (2) ½″ bypass for systems requiring large relief volume
Green-spring coded: Easy identification for service and replacement
Versatile ports: Dual inlets, large outlet, oversized bypass—fits heavy equipment setups
High temperature rating: 200 °F supports hot-water or rugged duty use
Applications:
Heavy-duty pressure washer systems with high volume and pressure demands
Fleet wash or mining/industrial cleaning rigs requiring multi-gun or high-flow operations
Replacement or upgrade for pump systems where large flow and high PSI are required
Systems requiring robust unloader valves built for continuous service
