Direct acting normally closed solenoid poppet valves available either AC or DC operated in plastic body. High flow with stainless steel seat and soft magnetic alloy and EPDM disc for hot water applications. Field replaceable seat/orifice design for flexibility.

PARAMETERS

To open: when the solenoid valve is energized, a magnetic field from the coil attracts the plunger covering the pilot orifice to lift off, causing system pressure (holding the diaphragm closed) to drop. As system pressure on the top of the diaphragm is reduced, full system pressure on the other side of the diaphragm acts to lift the diaphragm away from the main orifice, which allows media flow through the valve. Since the bleed orifice is dimensionally smaller than the pilot orifice, the system pressure cannot rebuild on the top of the diaphragm as long as the pilot orifice remains open.

To close: when the solenoid valve is de-energized, it releases its hold on the plunger, allowing the plunger spring forces the plunger to covers the main orifice. The system pressure builds up on the top of the diaphragm through the bleed orifice, forcing the diaphragm down until it covers the main orifice and stops media flow through the valve
