Festo
550161
Basic valve CPE18-P1-5/3B-1/4
The Festo part number 550161 is a 5/3-way pressurized industrial component utilizing a piston gate valve structural design with an 18 mm width and an 8 mm nominal width. Actuated via an ISO 15218 pilot control interface with internal pilot air supply, this piloted valve delivers a normal nominal flow rate of 1300 l/min through G1/4 pneumatic working ports across an operating pressure range of 0.25 MPa to 1 MPa (2.5 bar to 10 bar). It features an adjustable exhaust air function, a soft sealing principle, a mechanical spring reset method, and a non-detenting manual override for mounting in any position. This component carries c UL us recognition, CE marking per the EU low voltage directive, UKCA marking, and maritime classification certified by DNV and UL.
