172951

Name: Festo 172951 start valve HEE-3/4-D-MAXI-110
Brand: Festo

start valve HEE-3/4-D-MAXI-110

The Festo part number 172951 is an electrically actuated industrial component featuring a piston slide design structure and a soft sealing principle. This piloted 3/2 closed, monostable valve operates at a working pressure of 2.5 to 16 bar, delivering a standard nominal flow rate of 6,000 l/min with a 100% duty cycle and mechanical spring reset. It operates on 110 V AC (50/60 Hz) power with a detenting manual override, handles compressed air under ISO8573-1:2010 [7:4:4] or inert gases at temperatures from -10 to 60 °C, and carries a CRC 2 moderate corrosion resistance classification with RoHS-conforming materials.
