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.

Available types and options
