1.1 DESCRIPTION The Lin-E-Aire
tion of the control valve. The opening, closing or throttling of the valve plug in the valve body is accomplished by varying the air pressure to the diaphragm in the actuator. This pressure is trans­mitted from a control device, which may be controlling pressure, liquid level, temperature or flow.
®
Valve Actuators are used for automatic opera-
Thus, by selection of actuator and control valve plug action, either push-to-close or push-to-open, the control valve will either open or close on failure of air pressure to diaphragm.
The spring and diaphragm are completely enclosed to protect them from dust, dirt and other foreign matter. Spring adjustments are made with a ball bearing spring adjustment sleeve. Diaphragm and spring assembly may easily be removed for replacement or substitution.
Two types of actuators are used for process control, the choice of either depends upon the valve action desired in case of air supply failure. There are two types
Air-to-Lower - Termination Nos. 220 thru 223, 240 thru 244, Figure 1. In this type of actuator, air pressure moves the push rod downward compressing the spring. In the event of air failure, the push rod moves to its extreme upward position.
Air-to-Raise - Termination Nos. 230, 231, 233, 250 thru 254, Figure 2. In this type of actuator, air pressure moves the push rod upward compressing the spring. In the event of air failure, the push rod moves to its extreme downward position.
The construction and operating range are listed on the data plate mounted on actuator. Actuator size and spring are selected to meet the requirements of the application. In service the actuator should create full travel of the valve plug when the pressure range indicated on data plate is applied. This pressure range is most generally 3 to 15 psi (20 to 100 kPa), but other ranges are avail­able.
For precise control of valve plug position or where two valves are to be operated in sequence by one control device, a W.E. Anderson valve positioner, Catalog Number 100N or 165, is rec­ommended.
