The BLEED-360 bleed valve prevents the pressure from increasing in the pilot circuit by creating microleaks.

  • When the pilot circuit is not pressurized, the bleed valve is open (piston retracted).
  • When the extinguishing system is activated, the bleed valve closes (piston extended).

The bleed valve is mounted on a pneumatic actuator: ACTF230-PNEUMX or ACTF230-PNEUMD.

Limitations

The number of bleed valves which can be installed on an extinguishing system controlled by a pilot cylinder depends on the piloting gas supply tank. With Sinorix™ gas extinguishing systems, piloting elements (pilot cylinder, pressure reducing valve, selector valve) can be used to supply a maximum of:

  • 5 alarm devices (SPAH10-A pneumatic alarm horn),
  • 7 bleed valves.
