FunctionThe solenoid valve consists of an electropneumatic binary con-verter with manual override and integrated poppet valve actu-ated on one side with return spring.The pilot supply for the electropneumatic binary converter is fed internally through port 1 or externally through port 9. By turning the turnable gasket, the pilot supply can be changed (see Mounting and Operating Instructions u EB 3967).The pressure reducer reduces the pilot pressure to 1.4 bar.In the idle position, the flapper is lifted off the outlet nozzle by the spring. As a result, a pressure lower than the deactivation pressure of the integrated poppet valve builds up in the pres-sure divider, which consists of the restrictor and outlet nozzle. When the solenoid coil is energized by an electric binary sig-nal, the outlet nozzle is closed by the flapper against the force of the spring. This causes the pressure in the pressure divider to rise above the activation pressure of the integrated poppet valve and switches it to the operating position. After the sole-noid coil is de-energized, the integrated poppet valve is switched to the idle position again by a return spring.Optionally, the solenoid valve can be upgraded to become a pneumatic poppet valve actuated on one side. This results in higher KVS coefficients (see Data Sheet u T 3756).
