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.
