Janatics DS2 Series Pneumatic Solenoid Valve, 5/2 Way, G 1/4" Port, 24V DC Coil & Connector with Red LED Indicator & Protection Circuit, DS255SR61-WT1R0

Parker P2LBX512ESNXB549

Parker Viking Xtreme — P2LBX (G1/4)

Parker P2LBX512ESNXB549 — Viking Xtreme 5/2-way directional control valve: G1/4 ports, single solenoid with spring return, 24 V DC, 15 mm solenoid, internal pilot supply, 10 bar maximum. The Janatics DS255SR61-WT1R0 shown here matches it on valve function, port size, coil voltage and maximum working pressure, and it shifts from 2 bar where the Parker needs 3.5 bar. 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. 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. This valve is supplied complete with a 22 mm coil and a PG9 connector carrying a red LED and a varistor for over-voltage protection; on the Parker side both of those are options within the separately ordered plug, so compare the full assembly rather than the valve alone. On flow the two are close: 1200 l/min here against 1290 l/min for the Parker, both measured at 6 bar inlet with a 1 bar pressure drop.

Festo CPE18-M1H-5L-1/4 (Festo 163142) - unchanged, confirmed twice

Festo CPE Compact Performance — CPE18 (G1/4)

Festo CPE18-M1H-5L-1/4 (Festo part no. 163142) - the 5/2-way single-solenoid, G1/4, 24 V DC Compact Performance valve this Janatics DS255SR61-WT1R0 stands in for. Both are internally piloted spool valves that reset on a pneumatic spring, and both are IP65 with the connector 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. Working pressure is 2 to 10 bar, against 2.5 to 10 bar for the Festo valve. 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 red LED and the varistor in this valve's connector have no counterpart in the Festo part number, because Festo puts both the indicator and the surge suppression in separately ordered plug-socket accessories; the coil here 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.
