In purely pneumatic control systems a pilot-operated valve does the job of a relay. This 5/2-way pneumatic valve switches with a pilot pressure of 2 to 8 bar and passes 1150 l/min at connection G 1/4". The switching function is Impulse valve. The materials are body and spool aluminium, seals NBR, pilot polyamide.
Advantages
- Service life min. 40 million switching cycles, enough for continuous multi-shift operation.
- Connection G 1/4" and exhaust G 1/4", so the piping follows the existing line network.
- Media oiled and non-oiled, filtered compressed air, so no separate treatment is needed.
- Pilot pressure of 2 to 8 bar, so the signal can come from the same network.
- Flow rate of 1150 l/min, so the connected actuator moves without the valve throttling it.
