Festo
550172
Proportional directional control valve VPWP-8-
The Festo 550172 is a 5/3 proportional directional control valve featuring a closed piston gate valve structural design with integrated pressure sensors and an 8 mm nominal width. This electrical, directly controlled component operates within a pressure range of 0 bar to 10 bar, a nominal operating pressure of 6 bar (87 psi), and delivers a normal nominal flow rate of 1400 l/min utilizing a hard sealing principle. Powered by a 24 V DC nominal operating voltage with an 18 V to 30 V DC range, it incorporates LED status indications, a magnetic spring reset method, and a VPWP safety position that approaches a blocked mid-position during control interface malfunctions.

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.
