Description
The PN9400 series are a compact range of linear pneumatic
actuators. They have been designed for matching the requirements
of valves at various differential pressures. Each actuator is fitted
with a mechanical travel indicator and incorporates a fully-rolling
diaphragm, which provides good linearity over the operating stroke.
