Name: Festo 1709707 Switch-off valve PAHL-SM-RE
Brand: Festo

Switch-off valve PAHL-SM-RE

The Festo 1709707 is an electrical, pilot-actuated piston poppet valve featuring a soft sealing principle and a 2x2/2-way, single solenoid, open valve function with external pilot air supply. This component operates within a working pressure range of 0 to 50 bar and a pilot pressure range of 6 to 10 bar, incorporating a mechanical spring reset, normally open contact switching element function, and a 100% duty cycle. It delivers safety functions for exhausting the control chamber to category 3, Performance Level d, supported by CCF measures, detenting and pushing manual override, LED signal status and sensor displays, and switching position sensing with a sensor.
