Competitively priced
The M/20132 range of 3-port in-line valves has been
introduced to complement ourM/20152 5-port models
and eventually to replace our S/441 models wit h valves
of smart, modern appearance and high performance at
competitive prices. They use the same static seal design
as the M/20152 and incorporate many of the same
components.
These valves are· suitable for many applications, in
particular the control of larger single acting cylinders
and cylinders with long stroke lengths, circuit switching
and the pilot control of large directional control valves
involving lengthy pilot lines.
Their compact size and neat styling enables them to
provide clean, tidy installations
especially when
mounted on a fiat surface. They are well suited to use in
control cabinets and the M/201 32/29 has provision
for panel mounting.
The solenoid used on the M/20132/122
model is a
new 22mm unit featuring a snap-Iock retainer for
quickand easycoil removal. Thecoil assemblymaybe rotated through 360° at 90° intervals. The valve is suitable
for use as either "normally closed" or "normally open".
It is supplied as a "normally closed" valveand

Description
Pressure set - reset
Button set, button or pressure reset
Pressure actuated, spring return
Solenoid pilot actuated, spring return
"normally open" operation is required the top cover and
solenoid base assembly should be rotated through 180°.
When mounting, the axis of the main spool must be
kept in a horizontal piane in the case of the -/3 and
-/29 models,
These valves are also suitable for use with vacuum
supplies down to 760 mm Hg except for those
models having an internat pilot supply, i.e. -/122.
