Normally Closed
Design:
2-way solenoid valve, direct acting, normally closed (Circuit
function A).
Seal Materials and Fluids handled:
See Table.
Fluid and Ambient Temperature:
See Table.
Pressure Range:
Maximum inlet pressure see label on valve.
Installation:
Before installing valve ensure that piping etc. is free of foreign
matter (metal fillings, seal materials, welding scale etc.). Instal-
lation as required but preferably with coil uppermost. Installati-
on in this position tends to prevent foreign matter remaining in
core tube (increased life). Do not put any loads on coil unit.
Type 0255: PTFE tape is recommended for sealing ports.
Arrow on valve body indicates flow direction. Mounting is
accomplished by 2 holes 6.5 mm thru valve body.
