8 Principle of Operation1) 3-Way ControlThis control device admits pressure into the control chamber, closing the valve, or relieves pressure to the atmosphere, fully opens the ) 2-WAY ELECTRIC CONTROLA solenoid operator plugs the control chamber outlet. A permanent connection from the upstream to the control chamber ensures line pressure in the chamber and thus valve closure. Energizing the solenoid operator causes the control chamber to drain to downstream, opening the CLOSEDVALVE OPENEDENERGIZEDVALVE OPENEDDE - ENERGIZEDVALVE CLOSEDM odel Selection TableModel759596 MaterialGRPuPVCuPVCC onnectionTHTHSWS izeinch3/4111/2221/233346mm2025405065808 090110160 Structural VersioncodeBasic- ThrottlingT Integral 2-Way Electric Control ( Dorot Solenoid)E/D2 Integral 3-Way Electric Control (Gemsol Solenoid)
