The PA by-pass valve VB85RV can work with pressures up to 280 bar and with flow rates up to 80 l/min. The body is made of brass and the valve is equipped with two high-pressure inlets and two by-pass outlets that ensure maximum ease of installation. The performances offered by the VB85 make it suitable for use with pumps designed to work on washing systems that require large water flow rates: car wash gantries, high pressure fire-fighting systems and small or medium-size vehicles for urban cleaning and sewer jetting.
