The following are the three principal diaphragm valves, each distinguished by the kind of power used to actuate them: • Hydraulic-actuated valves • Solenoid-actuated valves • Heat-motor-actuated valves A hydraulic-actuated valve utilizes a hydraulic element to provide both the thermostatic sensing means and the power for valve operation. The closed hydraulic sensing and actuating device …
