Name: Festo 550154 Basic valve CPE18-P1-5LS-1/4
Brand: Festo

Basic valve CPE18-P1-5LS-1/4

The Festo 550154 is an 18 mm wide industrial component featuring a 5/2-way monostable valve function with a piston gate valve structural design and soft sealing principle. This piloted valve operates across a pressure range of -0.09 MPa to 1 MPa (-0.9 bar to 10 bar) via an ISO 15218 pilot control interface with external pilot air supply and an adjustable exhaust air function. It delivers a normal nominal flow rate of 1500 l/min through G1/4 pneumatic working ports, utilizing a pneumatic spring reset method and a non-detenting manual override in any mounting position. The unit carries c UL us recognition, CE marking per the EU low voltage directive, UKCA marking, and DNV maritime classification.

Why 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.

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
