3/2-way pneumatic valve, spring return (NC), G 1/4", 800 l/min, nominal size 4.5 mm, 1.5 to 8 bar

In purely pneumatic control systems a pilot-operated valve does the job of a relay. This 3/2-way pneumatic valve switches with a pilot pressure of 2 to 8 bar and passes 800 l/min at connection G 1/4". The switching function is spring return (NC). The materials are body and spool aluminium, seals NBR, pilot polyamide.

Advantages

• Switching function spring return (NC), so the rest position is clearly defined.
• Nominal size of 4.5 mm, which defines the usable cross section of the switching position.
• Operating pressure of 1.5 to 8 bar, which fixes the permissible working range.
• Materials body and spool aluminium, seals NBR, pilot polyamide, matched to the intended service.
• Temperature range of -5 to +60 °C, which covers use in the machine room as well as outdoors.

Applications

• Plants operated within the temperature range -5 to +60 °C.
• Replacement of a defective valve of the same type in existing machines.
• Control of double-acting cylinders with an air demand up to 800 l/min.
• Sequencing of pneumatic axes with connection G 1/4" in handling equipment.
