DescriptionSolenoid valve for filtered, lubricated 1) or oil-freecompressed air, instrument air, nitrogen and other neutralfluids.

Temperature min.: 25 CTemperature max.: See specifications for

solenoids (Page 3)Operating pressure: 2.5 to 8 bar with internal controlpressure supply0 to 8 bar with external controlpressure supply

Auxiliary power valve: Only with external controlpressure supplyPort 12: 2.5 to 8 bar

Solenoid: DC, AC or intrinsically safecircuits

Mounting position: OptionalMaterial:Valve body: Hard anodized aluminium/

stainless steelSeals: AU/NBR

Featuresl Exhaust air feedbackl High flow ratel Maintenance-freel Crossover-free switching, switch-over function guaran-

teed even with small cross section air supply.l Safety function in the event of power failure provided

by mechanical return spring (version 1 with solenoid).l Can be fitted with manual override with or without lock.l Suitable for use in exposed locations with severe

environmental conditions.l Minimal electrical power consumption therefore

many safety ratings possible, e.g. EEx ia IIC T6.l Valve interior protected from contamination.l Pilot valve protected from contamination by control

fluid.

1) Oil recommendation: Shell Hydrol DO 32, ESSO Febis K 32 (as of July 1992) or comparable oils with DVI values < 8 (DIN 53521) andISO viscosity class 32-46 (DIN 51519).
