Festo
173897
On/off valve HE-3/4-D-MIDI-NPT
The Festo 173897 is a 3/2-way bistable piston gate valve featuring a 55 mm width, soft sealing principle, and manual actuation with no manual override. It operates within a pressure range of 0 MPa to 1.6 MPa and achieves a normal nominal flow rate of 3800 l/min using compressed air as per ISO 8573-1:2010 [7:4:4] or inert gases. Built for in-line installation or mounting with accessories, this RoHS-compliant component maintains a 100% duty cycle across a medium and ambient temperature range of -10 °C to 60 °C.

Request a QuoteWhy 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.
