PULSAR 4RV with microswitch

Pulsar 4 RV unloader valve with microswitch

Latest version of the historic PA Pulsar by-pass valve. The Pulsar 4rv by-pass valve can be used with working pressures up to 280 bar and with flow rates up to 40 l/min. The electrical switch is mechanically controlled thanks to the movement of the shaft. It is equipped with two inlets and two by-pass outlets that make the valve very versatile and easy to install in different positions. The body is made of brass. The performances of the Pulsar, together with its versatility and ease of installation, suggest its use on washing systems designed to optimize space, especially high pressure washers or self-service car wash systems. The Pulsar is available in different versions: with white spring (160 bar) and with blue spring (280 bar), with or without the pressure gauge port.
