Name: Festo 172954 start valve HEE-1-D-MAXI-110
Brand: Festo

start valve HEE-1-D-MAXI-110

The Festo 172954 is a 3/2 closed, monostable industrial component featuring an electrically actuated piston slide design with soft sealing and a detenting manual override. It operates within a working pressure range of 2.5 to 16 bar, delivers a standard nominal flow rate of 6,500 l/min, and supports a 100% duty cycle on 110 V AC (50/60 Hz) power with a permissible voltage fluctuation of +/- 10%. Constructed with a CRC 2 moderate corrosion resistance classification and RoHS-conforming materials, this piloted valve accommodates compressed air per ISO 8573-1:2010 [7:4:4] or inert gases across a medium temperature range of -10 to 60 °C.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
