Janatics DS2 Series Pneumatic Solenoid Valve, 5/2 Way, G 1/4" Port, Double Solenoid, 24V DC Coils with Connectors, DS255SS61-W

Festo CPE18-M1H-5J-1/4 (Festo 163143) - unchanged, confirmed twice

Festo CPE Compact Performance — CPE18 (G1/4)

Festo CPE18-M1H-5J-1/4 (Festo part no. 163143) - the 5/2-way double-solenoid, G1/4, 24 V DC Compact Performance valve this Janatics DS255SS61-W stands in for. Both are internally piloted bistable spool valves, both run 2 to 10 bar, and both are IP65 with the connectors fitted. Ports 1, 2 and 4 are G1/4 as on the Festo valve, but exhaust ports 3 and 5 are G1/8 where Festo uses G1/4, so exhaust fittings and silencers will not carry over. Rated flow is 1200 l/min inlet to outlet and 700 l/min outlet to exhaust, measured at 6 bar inlet with a 1 bar pressure drop; Festo publishes 1500 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 read the two as indicative rather than measured alike. 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 coils are supplied with their own PG9 connectors on 22 mm coils, where the Festo valve takes a DIN EN 175301-803 form C plug socket, so a Festo socket or cable will not transfer.

Parker P2LBX512EENXB549

Parker Viking Xtreme — P2LBX (G1/4)

Parker P2LBX512EENXB549 — Viking Xtreme 5/2-way directional control valve: G1/4 ports, double solenoid, 24 V DC, 15 mm solenoid, internal pilot supply, 10 bar maximum. The Janatics DS255SS61-W shown here matches it on valve function, coil voltage and maximum working pressure, and the two are closely matched on flow: 1200 l/min here against 1290 l/min for the Parker, both measured at 6 bar inlet with a 1 bar pressure drop. Three points to check before you order. Port threads: the inlet and both outlet ports are G1/4 on either valve, but on this valve the two exhaust ports are G1/8, where the Parker part is G1/4 on all five body ports. Silencers, exhaust restrictors or exhaust piping sized for the Parker will need G1/8 fittings here. Temperature: this valve is rated +5 °C to +60 °C, where the Parker part is rated -10 °C to +50 °C, so it is not a like-for-like choice below +5 °C, and its minimum working pressure is 2 bar against 1.5 bar for the Parker. Supply: the Parker part number covers the valve and solenoid only, with the plug ordered separately and built to the 15 mm Form C / ISO 15217 pattern, whereas this valve is supplied complete with 22 mm coils and PG9 connectors. If you are reusing existing wired plugs, check the connector form before ordering.
