F243 solenoid cylinder valve DN12 for fire suppression systems
Operating mode: The valves F243 operate according to the pressure difference principle.
By actuating the release device, the integrated pilot valve into the quick-release valve opens and the upper pressure
chamber vents immediately. This pressure drop causes that the cylinder pressure pushes the closing piston in the open position. The quick-release valve is now open.
Design: Total discharge (TD -> total discharge of the cylinder after activation)
The quick-release valves F243 can be triggered electrically, manually and pneumatically.
The cylinder is filled by using the valve outlet (see chapter 11).
For the protection against inacceptable high pressure every valve is equipped with a burst disc safety device.
Quick-release valves for CO2 purposes are not equipped with a pressure gauge connection.
