Rotary Diaphragm Valve Actuators

Rotary Diaphragm Actuator: RD SPRING-DIAPHRAGM ACTUATOR

Rotary diaphragm actuators are often used for lower air pressure applications or when actuation by other inert gases or non-compressible fluids such as water and oil is preferred.  Constructed with a ductile iron or carbon steel cast housing, a UV resistant polyester powder coat is applied to protect the actuator in most environments.  Rotary diaphragm actuators can be operated at extreme temperatures, as low as -40ºF and as high as 392ºF.

 

The rolling Buna-N diaphragm style used has a special layered design including polyamine fabric to maximize longevity.  The low friction UMW polyethylene bearing provides very smooth actuation.  Double travel stops enable fully opened or closed adjustment.
