The driving device of bevel gear plate valve can be electric, pneumatic, manual, bevel gear rotation and other devices. The air filter, solenoid valve and sensor can be installed on the pneumatic device. If the above driving device is installed, the pneumatic device shall be specified in the contract.

Circular desulfurization and denitration special valves are commonly used in smoke pipes and air ducts in power plants, desulfurization and out-of-stock flue gas system industries as intercepting media. The opening and closing angle of the air door is 90 ℃. It has the two functions of full switch, so that all media in a pipeline of the system can circulate or close.

The advantage of the electric eccentric half ball valve is that the fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length. Simple structure, small size and light weight.

The gas release valve is mainly used for blast furnace and gas evacuation and emission, and can also be used for flue gas emission. The release valve is a safety warning device for pipeline transportation of flammable and explosive gases
