Design:
3-way solenoid valve, internally piloted, normally closed
(Circuit function C) or normally open (Circuit function D).
With manual override.
Seal Materials and Fluids handled:
See Table1.
Fluid and Ambient Temperature:
For Hazardous Locations Div. 1 (T6 rated)
Max. Ambient Temperature
104 °F (40 °C)
Max. Fluid Temperature 140 °F (60 °C)
For Hazardous Locations Div. 2 and Ordinary Locations:
See Table1.
Pressure Range:
Minimum pressure differential between inlet and outlet port is
15 PSI.
Maximum inlet pressure see label on valve.
Installation:
Installation position as required. Ensure exhaust outlets for
pilot valve and main valve remain unrestricted but protect
against entry of dust, water and foreign matter. Pipework
should be clean. Do not put any loads on coil unit. Pipework
should be supported and installed to prevent strain on valve
body. Fittings should be sealed with PTFE tape, max. torque
80 in-lbs. 1/4 inch trough holes are provided for mounting.
Maximum torque for mounting 25 in-lbs.
Voltage 12V or 24V
