Operating Instructions 0605/08_EU-EN_00893136
Design:
2-way solenoid valve, internally piloted, normally closed
(Circuit function A) or normally open (Circuit function B).
Seal Materials and Fluids handled:
See Table1.
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. 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:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, seal material, welding scale etc.). PTFE
tape is recommended for sealing ports. Arrow on valve body
gives flow direction. Installation as required but preferable
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.
