2P160-250 Series 2/2 Direct Lift Diaphragm Normally Closed Solenoid Valve:
This valve is a two-way, normally closed, direct lift, zero differential solenoid valve. 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 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.

ALL standard valves are supplied with Continuous Duty Coils of the proper class of insulation for the service indicated on the valve. It is normal for the coil temperature may become hot after being energized for extended periods. Smoke or burning odor indicates excessive coil temperature and the power should be disconnected to the coil immediately.

CAUTION: Do not energize the solenoid coil when it is not installed onto the valve. It may cause it to overheat and create a fire hazard.

SERVICE LIFE: The service life of the solenoid valve depends on the operating conditions such as pressure, temperature, type of medium, and the voltage.

Electrical Coil Connections

• To Connect a DIN Coil:
  
  
  • Remove the Philips screw from the plastic housting & unplug from the DIN coil.
  • Use the removed screw to push the terminal block out of the plastic DIN housing.
  • Note the "1", "2", and ground "⏚" symbols.
    • For DC DIN Coils, connect "1" to your positive lead and "2" to your negative lead.
    • For AC DIN Coils, connect "1" to your HOT lead, "2" to your NEUTRAL lead, and "⏚" to your ground lead, if required.


• To Connect a Grommet Coil:
  
  
  • For DC Coils, connect the red wire to your positive lead and the black wire to your negative lead.
  • For AC Coils, connect the black wire to your HOT lead and the white wire to your NEUTRAL lead.
  • For Coils provided with Molded Cables, the color of the wire indicates the type of lead:
    • GREEN = Ground Wire
    • BLUE = Positive or HOT Wire
    • BROWN = Negative or Neutral Wire
