Controls or defrosts; closes when de-energized.
Regulates for defrost/temp; opens wide for cooling.
Regulates at different settings when energized/de-energized.
Maintains set-for difference between inlet and outlet.
Opens when pressure exceeds setting, then reseats.
Controls outlet pressure by opening as downstream pressure falls.
Pneumatic signal increases inlet pressure 1:1 with temperature.
Vapor pressure capillary modulates regulator open with temperature rise.
Electronic pilot/controller provides precise temperature control.
Motor changes pressure setting per temperature controller.

Maintains set differential between inlet and outlet.
Air pressure on diaphragm adjusts inlet pressure.
Electronic actuator changes pressure set point.
Bulb senses temperature to modulate regulator.
Inlet pressure modulated via inlet control module.
Opens when inlet pressure exceeds relief setting.
Maintains set differential pressure using external sensing.
Controls outlet pressure by modulating inlet to piston.
Closes tight when solenoid control module is de-energized.
Opens wide when solenoid control module is energized.
Operates at different settings based on solenoid state.
Pneumatic controller adjusts air pressure to diaphragm.
Bulb senses temperature to modulate regulator.
Electronic actuator and controller for precise temperature control.
Motor response to controller alters pressure setting.
