STANDARD SPECIFICATIONS:
For Series LF, LX 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:
Port size 3/8” and 1/2” inlet: 9.8 VA on AC; 7.5 watts on DC.
Port size 3/4 thru 2
1/2” 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.
Port Threads: NPT, BSPP.
Note: For fluid applications, consult ROSS.
IMPORTANT NOTE: Please read carefully and thoroughly all of the CAUTIONS on the inside back cover.
* For models with external pilot supply, replace shaded “1” in the model number with a “5”, e.g., LF13NA37501Z.
For BSPP threads, replace “N” in the model number with a “D”, e.g., LF13DA37101W.
For 120 volts AC, 50/60 Hz, replace suffix “W” with “Z”, e.g., LF13NA37101Z.
Electrical connectors not included, see below for accessories.
