Operating Instructions
Type 5281
Design:
2-way solenoid valve, direct acting, normally closed (Circuit
function A).
Seal Materials and Fluids handled:
See Table 1.
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)
The UL-listed valve for Hazardous Locations is suitable for the
fluids air, inert gas, water and gasoline.
For Hazardous Locations Div. 1 (T6 rated)
Max. Ambient Temperature
104 °F (40 °C)
Max. Fluid Temperature
140 °F (60 °C)
For Intrinsically Safe Apparatus for use in Class I, II and III,
Division 1 Hazardous Locations (T6 rated)
Max. Ambient Temperature
140 °F (60 °C)
Max. Fluid Temperature
140 °F (60 °C)
For Hazardous Locations Div. 2 and Ordinary Locations:
See Table 1.
Pressure Range:
Maximum inlet pressure see label on valve.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal shavings, pipe sealing materials, welding scale
etc.). Installation as required but preferable with coil uppermost.
Installation in this position tends to prevent foreign matter
remaining in core tube (increased life). Do not put any loads on
coil unit.
PTFE tape is recommended for sealing ports. Mounting is
accomplished by means of four M4 x 8 mm tapped holes
located on the valve underside. Letters on valve body indicate
pressure port, exhaust and outlet of the valve.
