Festo CPE18-M3H-3GL-1/4 (Festo 163785) - unchanged, confirmed twice
Festo CPE Compact Performance — CPE18 (G1/4)
Festo CPE18-M3H-3GL-1/4 (Festo part no. 163785) - the 3/2-way normally-closed, G1/4 Compact Performance valve this Janatics DS245SR61-A stands in for. Both are internally piloted spool valves with a pneumatic spring return, both carry G1/4 on all three ports, and both are IP65 with the connector fitted. Coil voltage differs and should be checked against the supply before swapping: Festo rates this valve 230 V AC with a -15% / +10% tolerance, giving 195.5 to 253 V, where this coil is 220 V AC +/-10%, giving 198 to 242 V. M3 is the only 220-230 V option Festo builds in this size. Working pressure is 2 to 10 bar, against 2.5 to 10 bar for the Festo valve. Rated flow is 1200 l/min, measured at 6 bar inlet with a 1 bar pressure drop; Festo publishes 1300 l/min for its valve as a standard nominal flow rate referred to DIN 1343 standard conditions and does not state the test pressures behind that figure, so the two are close but not measured on a stated common basis. Rated -10 to +60 degC ambient against -5 to +50 degC for the Festo valve, on compressed air from +5 to +50 degC against Festo's -5 to +50 degC. The manual override is push-and-turn locking as standard, where the Festo valve's is non-detenting unless its locking accessory is fitted. The coil is supplied with its own PG9 connector on a 22 mm coil, where the Festo valve takes a DIN EN 175301-803 form C plug socket, so a Festo socket or cable will not transfer.
