Where no electrical power is available the control chain is built purely pneumatically. This 5/2-way pneumatic valve with connection G 1/4" carries 800 l/min and is switched over by an air pulse. The switching function is Impulse valve. The operating pressure is stated as 1.5 to 8 bar. The materials are body and spool aluminium, seals NBR, pilot polyamide.
Advantages
- Pilot pressure of 2 to 8 bar, so the signal can come from the same network.
- Flow rate of 800 l/min, so the connected actuator moves without the valve throttling it.
- Switching function Impulse valve, 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.
