The Model 710 is a solenoid controlled valve equipped with a 3-way solenoid pilot. The normally open solenoid applies pressure to the upper control chamber, harnessing valve differential pressure to power the diaphragm actuator, closing the main valve.

Energizing the solenoid vents control chamber pressure, causing the main valve to open fully. The lower control chamber is open to the atmosphere. In cases where the pipeline water is contaminated (corrosive, debris laden) external fluid is often used. For 10″ and larger valves, an accelerator quickens valve response.
