Masoneilan Type 37/38 Actuator

Masoneilan’s Type 37/38 pneumatic spring diaphragm actuator is a high performance design for use with linear stem motion valves. It features pressed steel cases, molded elastomeric diaphragms, and single piece yokes.

Masoneilan Type 37 direct acting and Type 38 reverse acting pneumatic spring diaphragm actuators are desined to provide high performance. Their features include:

* Heavy One-piece yoke: Provides maximum strength and rigidity.
* Diaphragm Cases: Pressed steel upper and lower cases combine lightness, high mechanical strength and adequate protection in the event of severe over-pressurization.
* Thrust Capability: Two actuator types and seven sizes provide a wide range of applications.
* Diaphragm: Molded elastomer with fabric insert for strength, long life and high sensitivity.
* Linearity: The molded diaphragm and deep cases minimize area change and produce a linear relationship between travel and air pressure.
