Linear Actuators

MP909D/E/H Pneumatic Damper Actuator

MP909D/E/H pneumatic damper actuators are rolling diaphragm, piston-type pneumatic damper actuators. These actuators are used for proportional control of variable volume terminal units, mixing boxes, and small- to medium-sized dampers.

MP909D/E/H Pneumatic Damper Actuator

MP909D/E/H pneumatic damper actuators are rolling diaphragm, piston-type pneumatic damper actuators. These actuators are used for proportional control of variable volume terminal units, mixing boxes, and small- to medium-sized dampers.

MP909D and E are manufactured with aluminum alloy housings and in only two stroke lengths with four spring ranges. The MP909H is an MP909E with a positive positioner providing an adjustable start point and 3, 5, or 10 psi (20, 35, or 70 kPa) span (operating range). An MP909E with a 5 to 10 psi (34 to 69 kPa) spring range can be converted to an equivalent MP909H by adding the MP909E positive positioner retrofit kit.
