Pneumatic Diaphragm Control Valve

Product Description

A pneumatic diaphragm control valve is a type of control valve that uses compressed air to actuate a diaphragm within the valve body. The diaphragm separates the valve body into two chambers, with one chamber connected to the compressed air source and the other chamber connected to the process fluid. The diaphragm moves in response to changes in the pressure of the compressed air, which in turn controls the flow of the process fluid through the valve.

This type of valve is commonly used in industrial applications where precise and reliable control of flow, pressure, or temperature is required. The pneumatic actuation system provides quick and precise response to changes in the process conditions, allowing the valve to maintain tight control over the flow of the process fluid.

The diaphragm control valve is available in different configurations, such as globe, angle, or straight-through, and with a variety of materials of construction to suit different process conditions. The valve may also be equipped with additional features, such as positioners, controllers, and limit switches, to provide enhanced control capabilities and monitoring.
