Pneumatic valve actuator
3 100 - 8 900 Nm, 5.5 bar, ATEX J+J AUTOMATION UK

The CH-air B Type actuator is assembled
using machined internal components
which produces a finished product
with a low friction coefficient. This
produces an actuator that offers durability
and reliability in service.
It is compliant with all the usual actuator
norms making it compatible with
similarly compliant valves, and position
monitoring, control and feedback devices.
Safety is a key feature, particularly in
spring return models, where the use of
pre-loaded spring capsules which fully
relax before the actuator’s end cap is
removed, protect engineers when servicing
the actuator.
An impressive 18 models make up the
range of the aluminium version, offering
a maximum double acting torque output
of 8900Nm at 5.5 bar air supply,
and 3100Nm end of spring torque for
the largest spring return model, based
on 5.5 bar air supply.
