The 2P025 Series Valves are normally closed, direct acting solenoid valves and do not require a minimum differential pressure to operate. As shown in the diagram below, when the coil is de-energized (left diagram), the plunger rests on the main orifice and is held in place by the plunger spring force, sealing the valve. When the coil is energized (right diagram), the solenoid lifts the plunger and allows the working medium to flow through the orifice. The working medium and flow direction are indicated in purple in the diagram.
STC's high performance direct acting plastic body solenoid valves offer reliability, compact and rugged designs, low power consumption, high-speed response, long-life cycle (over 10 million cycles), DIN connections and indicator lights, pre-wired electrical connections, manifold mounting options, and simple installation, maintenance, and control.
