About Valves electropneumatically operated

Electropneumatically actuated directional valves switch on an electrical signal, with the actual shift handled by a pneumatic pilot stage. The range works at operating pressures up to 10 bar, covers nominal sizes DN 5 to DN 15 and delivers flow rates from 50 to 2000 Nl/min. That makes cylinders and other actuators directly drivable from the control system.

What matters when choosing

• Function: from 3/2 NC and 3/2 NO through 5/2 monostable and bistable to 5/3 with closed, exhausted or pressurised centre position. Monostable valves drop back to their rest position when the signal is lost, bistable valves hold the last position.
• Voltage: 12 V DC, 24 V DC, 24 V AC, 110 V AC and 230 V AC, plus versions supplied without a voltage. It has to match the existing control system.
• Flow rate from 50 to 2000 Nl/min at DN 5 to 15: size it against cylinder volume and the cycle time you need.
• Connection: threaded ports M5 IG, G 1/8 IG, G 1/4 IG, G 3/8 IG and G 1/2 IG are listed, as well as flange versions. The connection type has to suit the planned mounting arrangement.
• Series: Reihe 70, Reihe 70 low temperature, Reihe BASIC, 3V, 4V and the Robustausführung. The low temperature variant works down to -40 °C media temperature.

Typical applications

• Driving double-acting cylinders in assembly and production machines
• Diverters and reject stations in conveying systems
• Clamping fixtures that need a defined rest position when the signal drops
• Grippers and handling units on pick-and-place lines
• Cold store and outdoor installations with media temperatures down to -40 °C

The intended medium is filtered compressed air, dry and unlubricated or lubricated depending on version. Once lubrication is introduced it has to be maintained continuously. 114 items are rated to protection class IP 65.
