Summary：

The quick-closing valve control system is a pneumatic remote control operation of each fuel tank, oil tank or daily fuel tank of the ship to close the valve to cut off the oil circuit, which can effectively prevent the fire from spreading in a fire emergency. Avoid major losses.

Work Principle：

The air source on board is input into the gas cylinder of the pneumatic speed closed valve control box, and the air pressure in the gas cylinder is kept constant through the pressure controller. The air in the cylinder is divided into the necessary paths through the distributor. In an emergency, quickly open the piston of the pneumatic quick-closing valve on the compressed air to push the pipeline to close quickly.
