Multi Spring Actuator MSA
Pneumatic Diaphragm Actuatur

The Forbes Marshall multi spring actuator model MSA is designed to be used with Series 100, 140 & 160 control valve bodies. The MSA series comes with a wide range of thrust values and the actuator is field reversible to suit your control action.

Its rolling diaphragm design offer high reliability, power and actuator speed with negligible friction. MSA actuators are compact, easy to install even in places with limited space and has a low volume air chamber that shortens reponse time.
