STANDARD SPECIFICATIONS:
For Series CX Pressure Controlled Valves.
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 250 psig (17 bar).
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.
Port Threads: NPT standard, BSPP.
Note: For liquid applications, consult ROSS.
* For BSPP threads, replace “N” in the model number with a “D”, e.g., CX34DA35501.
