Festo
165079
On/off valve HEL-3/8-D-MIDI
The Festo 165079 is a directly controlled 2/2-way closed monostable piston gate valve featuring a soft sealing principle and an adjustable exhaust air function with a mechanical spring reset. This pneumatic component operates within a pressure range of 0.3 MPa to 1.6 MPa (3 bar to 16 bar) and delivers a normal nominal flow rate of 3200 l/min, a C value of 16.5 l/sbar, and a b-value of 0.39 for compressed air or inert gases per ISO 8573-1:2010 [7:4:4] across a medium temperature of -10 °C to 60 °C. Designed with any mounting position, non-reversible flow direction, and moderate corrosion resistance class (CRC 2), it permits operation with oil lubrication and complies with VDMA24364-B1/B2-L LABS conformity.

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.
