See label on the valve.
Design:
2-way solenoid valve, internally piloted, normally closed
(Circuit function A) or normally open (Circuit function B).
Seal Materials and Fluids handled:
See Table.
Fluid and Ambient Temperature:
For Hazardous Locations Div. 1 (T4 rated)
Max. Ambient Temperature
104 °F (40 °C)
Max. Fluid Temperature 194 °F (90 °C)
For Hazardous Locations Div. 2 and Ordinary Locations:
See Table.
Pressure Range:
Minimum pressure differential between and outlet port is 7 PSI.
Maximum inlet pressure see label on valve.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, sealing materials, welding scale etc.).
PTFE tape is recommended for sealing ports. Arrow on valve
body gives flow direction. Installation as required but
preferably with coil uppermost. Installation in this position
tends to prevent foreign matter remaining in pilot valve
(increased life). A strainer upstream of valve, protects
against effects of foreign matter. Do not put any loads on coil
unit. Pipework should be supported such that valve body is
not under strain. Do not allow a pipe-end or sealing material
to block the pilot bore within the valve outlet. Inlet and outlet
of valve must be fullbore and pipework unrestricted.
