Festo
173916
start valve HEL-1/8-D-MINI-NPT
The Festo 173916 is a pneumatic 2/2 closed, monostable piston slide industrial component featuring a 40 mm grid dimension, direct piloting, and a mechanical spring reset. This valve operates at a working pressure of 3 to 16 bar, delivering a standard nominal flow rate of 1,000 l/min with a throttleable exhaust-air function, soft sealing principle, and non-reversible flow direction. It accommodates compressed air conforming to ISO 8573-1:2010 [7:4:4] or inert gases, permits lubricated operation, and maintains a CRC 2 moderate corrosion resistance classification with VDMA24364-B1/B2-L PWIS 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.
