The control valve, often referred to as the final control element, is a critical part of any control loop, as it performs the physical work and is the element that directly affects the process. Principles of Operation control valve is comprised of an actuator mounted to a valve. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator. The actuator, which can be pneumatically or electrically operated, directs the movement of the stem as dictated by the external control device. Pneumatic/Diaphragm ctuated Watson McDaniel Pneumatic s are direct acting and utilize an air signal from an external control device to create a modulating control action. The force of the air signal is received into the actuator through a top port and distributed across the full area of the actuator s diaphragm. The diaphragm presses down on the diaphragm plate and spring return assembly, which then moves the valve stem and plug assembly downward to stroke the valve. This actuator will move to a stem-out position in the event of air signal failure. The choice of valve action (stem-in-to-lose or stem-in-to-open) will determine its signal failure position. The Pneumatic ontrol Valve offers high quality at an economical price, incorporating many features found only on more expensive units. The following Models are available to provide the proper flow response required by the application: The W910, W910 & W910 are used for On/Off control applications, providing a quick-opening flow response when used with single or double seated valves. The W910T is used for proportional or PID control applications, providing a throttling flow response when used with double seated or 3-way valves. The W910EP & W910EP are used for proportional or PID control applications, providing equal percentage flow response when used with single seated valves Jones oulevard Limerick irport usiness enter Pottstown P Tel: Fax:
