2V130-250 Series 2/2 Pilot Operated Diaphragm Normally Closed Solenoid Valve:
This valve is a two-way, normally closed, pilot-operated diaphragm
valve. As shown in the diagrams below, when the coil is de-energized
(left diagram), the pilot plunger and diaphragm sit on their respective
orifices. The working medium flows through a tiny “bleed orifice” and
pressurizes the cavity above the diaphragm – this system pressure, along
with the spring force, seals the valve. When the valve is energized,
the pilot plunger allows the working medium to flow through the pilog
orifice. This releases the pressure above the diaphragm and causes it
to lift off of the main orifice, allowing the working medium to flow fully
through the valve. Since the bleed orifice is dimensionally smaller
than the main orifice, the system pressure cannot rebuild on the top of
the diaphragm as long as the main orifice remains open. The working
medium and flow direction are indicated in purple in the diagrams.

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.
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
