VR 3B Unloader Valve – 300 Bar – Built-in Bypass – Part No: 22621

The VR 3B Unloader Valve is a heavy-duty, pressure-regulating valve designed for high-performance pressure washer systems. It automatically relieves pressure from the pump when the trigger is released, protecting components and extending pump life.

Rated to a maximum pressure of 300 Bar (4350 PSI) with a maximum flow of 35 L/min, it’s suited to demanding applications and commercial-grade setups. The built-in bypass ensures safe and efficient operation, while the 1/2″ BSP female inlet and 3/8″ BSP male outlet provide easy connection to most common fittings.

Compatible with Annovi Reverberi pump ranges RW and RG, the VR 3B is a dependable upgrade or replacement option. A repair kit is available separately to support long-term maintenance.
