STANDARD SPECIFICATIONS:
For Series CX Solenoid Pilot Controlled Valves.
Pilot Solenoid: DC power. Rated for continuous duty.
Standard Voltages: 24 volts DC; 120 volts AC, 50/60 Hz.
Power Consumption: Per Solenoid: 3 VA on AC; 2.5 watts on DC.
Ambient/Media Temperature: 40° to 120°F (4° to 50°C).
Flow Media: Filtered air; 5 micron recommended.
Inlet Pressure: Vacuum to 145 psig (10 bar).
Pilot Pressure: 30 to 145 psig (2 to 10 bar). Must be equal to
or greater than inlet pressure. For vacuum service models a pilot
pressure of at least 30 psig (2 bar) is required.
Override: Standard on 2/2 valves, 3/8” thru 1” bodies and 3/2
valves, 3/8” and 1/2” bodies. Non-Locking.
Port Threads: NPT standard, BSPP.
Note: For fluid applications, consult ROSS.
