Firefighting Valve

General



Usage

  • Opens in 40 sec after receiving signal and closes in 35 sec to prevent to protect the pipeline from surge waves.
  • Operation proportion 1:4 (e.g.inlet pressure 20bar, outlet pressure 5bar.
  • No rubber parts used (which are inappropriate for high temperatures).
  • The valve is accompanies by an electronic system. The central control panel, the electronic commander SMS and the temperature sensor, can be placed in a distance up to 200m.
  • The electric power is 24V AC, and there is also a battery 12V DC which enables 4 -hour-operation.
  • The panel for manual operation and electical supply of 48V AC is located 5km away.
  • The electronic system can be programmed to receive and execute commands via SMS, to send information via SMS to the users and waits for a command to open the valve or not. If the temperature reaches a second preset point the valve is activated automatically and informs the central panel and the users via SMS.
  • The system executes a command only through a safety code, which prevents access to unauthorised users.
  • The valve can be activated from the manual operation panel which can be installed at a distance of 20km.
  • Depending on the valve diameter we can install 1 or 2 rotating water cannons of different length.

  • The fire fighting valve is a pioneering solution because it can face the fire at forehead, it is not affected by the weather conditions and can be installed in the most isolated and not easily accessible areas.
  • It detects the fire immediately, notifies the users and is activated to exhtinguise the fire.
