Power Pack valve VPH 15 E is multifunction unit which reduces the costs of connections and hoses/tubes by incorporating the functions of a pressure relief valve and a directional control valve to provide a bypass function. The pressure relief function is designed to limit the system pressure by draining surplus water fl ow from the pressure side, and to protect system components against overload as a result of pressure peaks. The valves are electrically-activated ON/OFF valves (closed (NC) or open (NO) when the coil is de-energized). The VPH 15 E valve is designed for use with drinking water, i.e. water containing no additives of any kind. (See EU drinking water directive EU 98/83/EC).
