Pneumatic diaphragm actuators
First Quarter 2007
Pneumatic systems & components
The Spirax-Mitech PN9000 series pneumatic diaphragm actuators are a compact range of linear actuators that are available in three diaphragm sizes 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.
Various types are available including standard, electroless nickel-plated, stainless steel, spring-extended and spring-retracted. Operating in a -20°C to +110°C temperature range, the actuators have a maximum operating inlet pressure of 6 bar g (600 kPa) and a maximum 30 mm actuator travel. Air supply connection is ¼" NPT (6,35 mm).
