* 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., CX34DA35501.

Additional Valve Information
Note: The Dale series pressure controlled valves require
both an external pilot supply and a control signal to operate
the valve. When a pressure control signal is applied the
valve shifts to the open position.
Complete valves-on-manifold assemblies can be ordered to fit your precise requirements.
When ordering the Dale Series CX manifold valves with different valve functions, please see page 16 for ordering information.
Operator: External pilot, solenoid actuated.
Applications: Pressure Decay, Bypass Fill and
Pressure isolation.
