Name: Festo 172943 On/off valve HEE-3/8-D-MIDI-230
Brand: Festo

On/off valve HEE-3/8-D-MIDI-230

The Festo 172943 is an electrically actuated piston gate valve featuring a 3/2-way, closed, monostable valve function with piloted control and a mechanical spring reset. This soft-sealed component operates within a pressure range of 0.25 MPa to 1.6 MPa, delivering a normal nominal flow rate of 3200 l/min and a C value of 15.7 l/sbar with a positive overlap lap and non-throttleable exhaust air function. Powered by a 230 V AC (50/60 Hz) coil requiring 5.0 VA initial power and 3.7 VA holding power, the unit supports a 100% duty cycle and accepts compressed air or inert gases conforming to ISO 8573-1:2010 [7:4:4].

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.
