Product Details

The Mini Matic 4B Unloader Valve is a compact and reliable pressure-regulating valve designed for high-pressure cleaning systems. Automatically relieving pump pressure upon trigger shut-off, it features a built-in bypass, ensuring pump safety and reducing stress on the system.

Rated to a maximum pressure of 180 Bar (2600 PSI) and handling up to 18 L/min, this unloader is ideal for small to mid-range cleaning units. It is compatible with several Annovi Reverberi pump ranges, including HPW, XT, RC, XM, RR, and RK models.

With a 1/2″ BSP female inlet and a 3/8″ BSP male outlet, installation is quick and straightforward. A repair kit is also available for ongoing maintenance and long-term value.
