DESCRIPTION
The TW series valves are manually operated, non-graduating,
on-off valves. They are extensively used in air systems to
control nonmodulating air controlled devices. They may be
lever or button operated, direct or remote control.
The TW-1
™
valve (Figure 1) is normally panel mounted and
can be provided with a steel, zinc or nylon manually operated
lever. Some are equipped with a steel lever with connectors
for Bowden cable control. All TW-1
™
valves have 1/8" NPT
ports.
The TW-3
™
valve (Figure 2) is lever operated, either direct or
remote and differs from the TW-1
™
valve in having 1/4" NPT
ports and a larger body and capacity. Some versions have a
heavy inlet valve spring making them suitable for vacuum
control.
TW-4
™
(Figure 3) and TW-5
™
valves are similar to the TW-1
™
valve except the plunger is designed for a push button
(TW-4
™
valve), giving momentary application whenever the
button is depressed. The TW-5
™
valve is similar, but has an
extended plunger.
