Festo
34880
Piloted non return valve HGL-1/2-NPT
The Festo part number 34880 is an industrial component featuring an unlockable check valve function, 1/2 NPT pneumatic connection 1, and 1/2 NPT pneumatic connection 2 for screw-in mounting. This valve operates across a pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar) and a pilot pressure range of 0.1 MPa to 1 MPa (1 bar to 10 bar, or 14.5 psi to 145 psi), delivering a normal nominal flow rate from 0 l/min to 1600 l/min according to DIN 1343. It functions within an ambient and medium temperature range of -20 °C to 80 °C using compressed air as per ISO 8573-1:2010 [7:4:4], permits oil lubrication operation, conforms to VDMA24364-B1/B2-L LABS (PWIS), and features RoHS compliant materials.

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.
