Description

SPIRAX SARCO Pneumatic Actuators PN9000

SPIRAX SARCO Pneumatic Actuators

General information-

The PN9000 series actuators are a compact range of linear actuators that are available in four sizes. This range of actuators cocomprisesf four diaphragm sizes for matching the requirements of valves at various differential pressures. Each actuator has a mechanical travel indicator fitted and incorporates a fully-rolling diaphragm, except size 4, which provides good linearity over the operating stroke. 

Temperature range – 20 °C to + 110 °C
