Heavy-Duty Pressure Control for High-Flow Industrial Pump Systems
The VB85 RV Unloader Valve is engineered for reliable pressure regulation in high-flow, high-pressure water systems. With the ability to manage up to 80 L/min and withstand 4500 PSI, this unloader is ideal for demanding industrial applications, including hydro jetting, drain cleaning, pressure washing, and pump protection systems.
Built from robust, corrosion-resistant materials and designed for consistent performance under heavy workloads, the VB85 ensures smooth system operation by automatically redirecting excess water flow, preventing pressure spikes, and extending pump lifespan. Its ½” BSP female couplings allow easy integration into a wide range of industrial and commercial setups across Australia, especially within high-pressure cleaning and environmental services.
