* 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.

The CP series 3-way valves can be ported
from the bottom and attach directly to the
rod and cap end a cylinder. The CP series
3-way can also be supplied as a cartridge
valve that can be machined directly into
the cylinder heads. Both methods increase
speed, eliminate line loss, improve cylinder
control, and greatly reduce operating cost.

For BSPP threads, replace “N” in the model number with a “D”, e.g., CX14DA37501W.
For 120 volts AC, 50/60 Hz, replace suffix “W” with “Z”, e.g., CP14NA37501Z.
Electrical connectors not included, see page 7 for ordering information.
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.
