Model: UU261
Category: Pumps → Pump Accessories → Unloaders / Regulators
Type: Integrated Unloader with Pressure Switch – Regulating Unloader / Switch Assembly

The UU261 Unloader with Pressure Switch is a high-performance integrated regulating unloader and micro-switch assembly engineered for advanced pressure washer and steam combination systems. Designed to control both maximum and minimum system pressure, this unit features a tamper-resistant, operator-adjustable valve, allowing precise pressure limit setting while protecting critical system components.

Integrated Pressure Switch Function

The UU261 includes an STSP-NC A.C. micro switch mounted in place of the bypass fitting. When the system enters bypass mode, the unloader piston opens the normally-closed switch, allowing precise control of electrical components.
