What Is A Pneumatic Valve?

Pneumatic valves are valves driven by compressed air. This valve is composed of pneumatic actuator and valve, the use of compressed air to drive the movement of multiple groups of combined pneumatic piston in the actuator, the transmission of force to the beam and the characteristics of the inner curve track, drive the air core spindle for rotating movement, compressed air disc to each cylinder, change the inlet and outlet gas position to change the direction of spindle rotation, according to the requirements of the load required rotational torque, the number of cylinder combinations can be adjusted. Drive the load work.

Pneumatic valves are widely used in ships, mainly involving the ship's ventilation system, liquid cargo hold, fuel system, oil system, seawater system and so on. The pneumatic valves in these systems are mainly used to control the flow, pressure and direction of the gas to ensure the safety and normal operation of the ship.

Specifically, the pneumatic valve in the ventilation system is mainly used to regulate the air flow in the cabin to ensure the air circulation in the cabin; The pneumatic valves in the liquid cargo hold are mainly used to control the loading and unloading and conveying of liquids. Pneumatic valves in the fuel system and lubricating oil system are mainly used to control the supply and delivery of fuel and lubricating oil; The pneumatic valves in the seawater system are mainly used to discharge and regulate the seawater to ensure the cooling and cleaning of the ship.
