3/2-way solenoid valve, spring return (NO), G 1/8", 590 l/min, 24 V AC, aluminium body

Wherever compressed air has to be switched electrically, this pilot-operated 3/2-way solenoid valve links the control level to the pneumatic circuit. It runs on 24 V AC and draws only 3.5 VA, which keeps it compatible with common cabinet outputs. A flow rate of 590 l/min through the two G 1/8" working ports suits single-acting cylinders of medium bore as well as blow-off and cleaning duties. The valve is open in its home position, and only energising the coil closes the inlet and vents the outlet through the separate G 1/8" exhaust port. Response time stays below 25 ms at 5 bar.

Benefits

• 590 l/min of flow from a compact G 1/8" port thread
• Aluminium body and spool, NBR seals and a glass-fibre reinforced polyamide pilot
• Operating pressure of 1.5 to 10 bar covers standard network pressures
• IP 65 protection when combined with the size 0 standard connector
• Voltage tolerance of ± 10 % absorbs fluctuations in the 24 V AC supply
• Switching time below 25 ms at 5 bar for fast cycle rates

Applications

• Control of single-acting pneumatic cylinders in assembly fixtures
• Timed blow-off nozzles for clearing and separating small parts
• Pressurising and venting of vacuum cups and clamping devices
• Release of compressed air circuits in cabinets with 24 V AC control voltage

Standards and conformity

The IP 65 rating applies to the combination of coil and size 0 standard connector. With a rectangular connector the rating drops to IP 40. The permissible control voltage tolerance is ± 10 %.
