3/2-way pneumatic valve, spring return (NC), G 1/2", nominal width 8 mm, 2250 l/min

Large cylinders, blow-off nozzles and air receivers need a valve that passes the required volume without a noticeable pressure drop. This 3/2-way version delivers 2250 l/min at a nominal width of 8 mm through G 1/2" ports. In the home position the passage is blocked and the working line is vented, and the spring restores that state as soon as the pilot pressure at the G 1/8" port disappears. Operating pressure covers 1.5 to 8 bar, the pilot pressure 2 to 8 bar. Body and spool of aluminium with NBR seals and a polyamide pilot section last for at least 40 million switching cycles.

Advantages

• 2250 l/min flow rate at a nominal width of 8 mm, sized for high volume consumers
• Spring return blocks the passage and vents the working line whenever pilot pressure is missing
• Service life of at least 40 million switching cycles
• Body and spool of aluminium, NBR seals, pilot section of polyamide
• Operating pressure 1.5 to 8 bar with a separate G 1/8" pilot port rated 2 to 8 bar
• Installation size of 103 mm x 50 mm x 34 mm, temperature range -5 to +60 °C

Applications

• Control of high volume cylinders that need a lot of air within a short time
• Blow-off and cleaning stations with nozzles of high air consumption
• Filling and venting compressed air receivers through a G 1/2" port
• Pneumatic main circuits switched by a pilot pressure of 2 to 8 bar
• Continuous duty in multi-shift operation thanks to 40 million switching cycles
