order tip
To purchase a
valve with
an air actuator installed
,
go directly to valve
ordering information.
Air actuators offer reliable performance under the most stringent conditions.
Low gas consumption and lightweight, compact construction make the air
actuator suitable for aerospace flight hardware applications as well as laboratory
or process applications.
The standard air actuator is rated for up to 80 psig at temperatures up to 70°C.
Generally speaking, valves which will be heated require a standoff assembly,
which locates the air actuator out of the heated zone and supports both the
valve and actuator. A high temperature model permits both valve and actuator
to be mounted within an oven (175°C maximum), but it is not recommended for
use below 50°C.
tech tip
The actuator’s rotation
must be properly
matched to the valve’s.
If you are converting
a manual valve to air
actuation and have any
doubts about which
actuator and hardware
you need, call our sales
or technical staff for
assistance.

The recommended method for
implementing a selector (multi
position) air actuator requires only a
single 4-way solenoid. Up to 80 psig
may be used without damaging the
valve or actuator. Bottled instrument
air or nitrogen is recommended.
If plant air from compressors must be
used, an oil separator and water dryer
are required.
Multiposition air actuators include a
rotary switch which may be connected
to a digital readout or your own
design.
