ALL Standard valves are supplied with CONTINUOUS DUTY COILS
of the proper class of insulation for the service indicated on the valve.
The coil temperature may become hot after being energized for extended
periods, but it is normal. Smoke or burning odor indicates excessive coil
temperature and should disconnect the power to the coil immediately.
VOLTAGES: Standard: 12-24V DC and 24-110-220-230V/50-60 Hz AC. Voltage
tolerances: +10% –5% for DC, +10%-15% for AC; .
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 |
|
For DIN Coil |
To connect 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 |
To connect 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. |
2L Series
2/2 Direct Lift Piston Normally Closed Solenoid Valve:
Description & Operation:
2L, 2LS
series valves are 2 way normally closed, internal DIRECT LIFT PISTON solenoid valves and require
ZERO OPERATING PRESSURE
DIFFERENTIAL. When the coil is energized, it lifts the pilot valve off the
pilot valve seat, opening the pilot orifice through the center of the piston to
the outlet side of the valve. This relieves the pressure from the top of the
piston ring and pressure under the piston ring forces the piston up to open
the main valve orifice. When the coil is de-energized, the pilot valve
returns to close the pilot orifice and pressure across the piston ring is
equalized through a timing orifice in the side of the piston or in the valve
body. The piston spring returns the piston to close the main valve orifice.
