HD & HDS Pressure Controllers

Inline pressure control valves for precise regulation of professional cleaning performance

This category covers HD & HDS Pressure Controllers designed for use with professional cold and hot water pressure washers, providing precise manual control of working pressure directly at the point of use. Pressure controllers are fitted inline between the trigger gun and the spray lance, allowing operators to adjust pressure output instantly without returning to the machine. This makes them particularly valuable in professional environments where cleaning tasks vary frequently between high-impact dirt removal and more delicate surface cleaning. By reducing or increasing pressure at the lance, operators can adapt safely to different materials, surfaces, and contamination levels while maintaining continuous workflow. Emphasis is placed on robust construction and reliable performance, with pressure controllers engineered to withstand high operating pressures, elevated water temperatures, and intensive daily use associated with professional HD and HDS equipment. These components also help reduce operator fatigue and improve safety by allowing finer control over spray impact and recoil. HD & HDS pressure controllers are available in versions compatible with the newer EASY!Lock Trapezoidal Thread, as well as metric thread versions used on legacy or some Classic models. Importantly, these connection standards relate specifically to the lance-to-gun interface, as the pressure controller sits between the trigger gun outlet and the spray lance inlet. Correct selection ensures secure sealing, safe operation, and reliable pressure regulation without leaks or pressure loss. As part of a professional pressure washing setup, pressure controllers provide greater flexibility, improved surface protection, and enhanced control, supporting efficient and adaptable cleaning performance across a wide range of demanding professional applications.
