C30 combined air valve is a multi-functional combined air valve integrating high-speed intake/exhaust valve and trace exhaust valve. It is specially designed for intelligent management of air in the system at different stages such as water filling, operation and emptying of pipes. The valve can quickly discharge a large amount of free air, continuously discharge dissolved gas, and instantaneously suck air when the system generates negative pressure, effectively prevent air resistance, eliminate water hammer, and avoid vacuum deformation of the pipeline. It is the key equipment to ensure safe, efficient and stable operation of the water conveyance system. It is widely used in long-distance water pipeline, high point and fluctuation section of municipal water supply network, main water inlet and outlet pipe of pump station, technical water supply system of hydropower station, main pipeline of industrial circulating water and fire water supply system of large buildings. Through intelligent air management, it effectively solves the three core problems of air resistance, water hammer and vacuum, and is an important guarantee to improve system safety and operation efficiency.

Features:
1.Three-stage intelligent air management
Large exhaust stage: when the pipe is filled with water, the large opening of the high-speed inlet/exhaust valve will quickly exhaust a large amount of free air.
2.Trace exhaust stage: when the system is operating, the trace exhaust valve will continuously and automatically discharge the slowly separated dissolved gas.
3.High-speed suction stage: when the system is emptied or the pump is stopped to generate negative pressure, the high-speed valve opens instantly to suck air to prevent the pipeline from destabilizing.
4.Special for high pressure and large flow conditions
The valve body is made of high-strength cast iron or nodular cast iron, with solid structure. It is applicable to high working pressure (such as PN16 and PN25) and large pipe diameter (DN50-DN300), meeting the requirements of severe working conditions of main pipe network.
5.Composite valve body structureThe large-displacement high-speed valve and the precision micro-valve are integrated into one valve body, with compact structure, comprehensive functions and convenient installation and maintenance.
