Series CP, CX Solenoid Pilot Controlled Valves
STANDARD SPECIFICATIONS:
For Series CP, CX Solenoid Pilot Controlled Valves.
Pilot Solenoid: AC or DC power. Rated for continuous duty.
Voltage and hertz ratings shown on pilot housing.
Standard Voltages: 24 volts DC; 120 volts AC 50/60 Hz.
Power Consumption:
2/2 Valves, NC & NO with 1/2” and 1” inlet, 3/2 Valves NC & NO
with 1/2” inlet: 3 VA on AC; 2.5 watts on DC.
2/2 Valves NC & NO with
1/2” and 21/2” inlet, 3/2 Valves NC & NO
with 1” inlet: 36 VA inrush, 23 VA holding on AC; 15 watts on DC.
Ambient Temperature: 40° to 120°F (4° to 50°C).
Media Temperature: 40° to 175°F (4° to 80°C).
Flow Media: Filtered air; 5 micron recommended.
Inlet Pressure: Vacuum to 145 psig (10 bar), (vacuum service
requires external pilot supply).
Pilot Pressure: 30 to 145 psig (2 to 10 bar). Must be equal
to or greater than inlet pressure. For vacuum service models
requiring external pilot supply, 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 liquid applications, consult ROSS.

* For models with external pilot supply, replace shaded “1” in the model number with a “5”, e.g., CP14NA37501W.
For BSPP threads, replace “N” in the model number with a “D”, e.g., CP14DA37101W.
For 120 volts AC, 50/60 Hz, replace suffix “W” with “Z”, e.g., CP14NA37101Z.
Electrical connectors not included, see page 7 for ordering information.
Models for vacuum, liquid or leak tight construction: for 2/2 valves replace prefix “CP” with “CX”, e.g., CX14NA37101W;
for 3/2 valves, consult ROSS.
