When the system is shut down or undergoing maintenance, be sure to drain all water or residual media from the valves and pipelines, especially for valves that have not been used for a long time.

Corrosive chemicals (acids, alkalis, solvents) require the use of corrosion-resistant materials such as stainless steel (304, 316) and Hastelloy for valve bodies, discs, and seats.

Compensate for installation errors: Allow for a certain degree of axial adjustment during the installation of valves or equipment connections to facilitate alignment.

Special medium valves are designed specifically for handling highly corrosive, highly toxic, ultra-low temperature, high viscosity, solid particles, or ultra-high purity media.

Cooling water regulating valve: used in the engine cooling system to regulate the flow of cooling water according to operating conditions, ensuring stable operation of the engine.
