2S & 2W160-500 Series

SKU: 2S & 2W160-500 Series

2S & 2W series 2/2 Direct Lift Diaphragm Normally Closed Solenoid Valve: 

 

To open: when the valve receives an electrical signal, a magnetic field is formed which attracts the plunger covering the main orifice to lift off, causing system pressure 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 to 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. When the system pressure is 0 PSI, the valve also can be operated.


To close: when the valve is de-energized, it releases its hold on the plunger. Then the plunger forced by the spring drops and 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. When the system pressure is 0 PSI, the valve still can be operated.

  • Installation Instructions

    For DIN Coil:

    1. Remove the Philip screw from the plastic housing and unplug it from the DIN coil.
    2. From the screw opening, push the terminal block out from the plastic housing.
    3. Note the 1, 2 and ground markings on underside of DIN enclosure.
    4. For DC DIN Coil, Connect 1 to Positive, 2 to Negative.
    5. For AC DIN Coil, connect 1 to HOT wire, 2 to Neutral wire, and if required connect ground to ground wire.

     

    For Grommet Coil:

    1.  For DC Coil, connect one of the two wires to Positive, and the other wire to Negative.
    2. For AC Coil, connect one of the two wires to HOT wire, and the other wire to neutral wire.
