STC 2PO160-1/2-4-D-E 1/2" NPT Direct Acting/Lift 2 Way Plastic Solenoid Valve, 220VAC, DIN

1/2" NPT Direct Acting/Lift Normally Open 2 Way Plastic Solenoid Valve (220VAC, DIN), EPDM Seal

To Close: When the valve is energized, the coil repels the plunger then the plunger covers the main orifice. The system pressure builds up on the top of the diaphragm/piston through the bleed orifice, forcing the diaphragm/piston down until it covers the main orifice and stops media flow through the valve. When the system pressure is 0PSI, the valve also can be operated.

To Open: When the valve is de-energized, the coil releases the plunger. The plunger uncovers the pilot orifice causing system pressure holding the diaphragm/piston closed to drop. As system pressure on the top of the diaphragm/piston is reduced, full system pressure on the opposite side of the diaphragm/piston acts to lift the diaphragm/piston away from the main orifice, which allows the full media flow through the valve. When the system pressure is 0PSI, the valve can be operated.
