Watson McDaniel Control Valves

A Control Valve is a device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from an external control device. In a process control loop, an Electronic Controller and Sensor is used in conjunction with a Control Valve to maintain a process variable at a desired set point. The controller compares the sensor signal to the set point and outputs the appropriate response signal to the control valve. The control valve will then modulate to provide the flow response required to maintain the process variable at the set point. In the case of a pneumatic control valve such as the W910 Series, a current-to-pressure (I/P) transducer is required to convert the electrical signal from the controller to the air pressure signal needed to operate the pneumatic valve. Watson McDaniel is unique in its ability to provide all the necessary components to create a complete control loop.

W910 & HB Series Pneumatic Control Valves

The Watson McDaniel W910 Series Pneumatic Control Valve offers high quality at an economical price and incorporates many features found only on more expensive units. A variety of models are available to provide the flow response required by the application.
