Festo
550159
Basic valve CPE18-P1-5/3E-1/4
The Festo 550159 is an 18 mm wide industrial component featuring a 5/3 exhausted valve function and a piston gate valve structural design with a soft sealing principle. It operates at pressures ranging from 0.25 MPa to 1 MPa (2.5 bar to 10 bar) and delivers a normal nominal flow rate of 1200 l/min through a G1/4 pneumatic working port. Actuation occurs via an ISO 15218 pilot control interface with internal pilot air supply, supported by a mechanical spring reset, an adjustable exhaust air function, and a non-detenting manual override. This unit carries c UL us recognition, CE marking per the EU low voltage directive, UKCA marking, and DNV maritime classification, with any mounting position permissible.

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.
