2L Series 2/2 Direct Lift Piston Normally Closed Solenoid Valve:
This valve is a two-way, normally closed, internal Pilot Piston solenoid valve and requires minimum 7PSI differential operating pressure. As shown in the diagrams below, when the coil is de-energized (left diagram), the pilot plunger and pison sit on their respective orifices. The working medium flows through a tiny "bleed orifice" and pressurizes the cavity above the piston - 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 pilot orifice. This releases the pressure above the diaphragm and causes the incoming pressure to push it 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.
