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.
