Product Overview
Pneumatic Diaphragm Actuator is a linear motion actuator commonly used for control valve applications. The actuator converts pneumatic air pressure into linear stem movement to open, close, or modulate the valve according to process control requirements.
This actuator type is typically installed on globe control valves and other linear control valve assemblies. It is suitable for process systems requiring stable valve modulation, accurate control response, and compatibility with pneumatic control accessories such as positioner and air filter regulator.
Key Features
Linear Motion Operation
Designed to provide straight-line stem movement for globe control valves and other linear control valve types.
Pneumatic Diaphragm Design
Uses pneumatic air pressure acting on a diaphragm to generate actuator movement for valve control.
Control Valve Compatible
Suitable for control valve assemblies used in process control, flow control, pressure control, and temperature control applications.
Positioner Ready
Can be combined with valve positioner for modulating control and improved valve positioning accuracy.
Yoke Mounted Construction
Designed for installation on linear valve yoke assemblies with stem connection to the valve plug.
Industrial Application
Suitable for industrial process piping systems requiring pneumatic valve automation and stable control performance.
