Valve assembly mainly has a complete interchangeable method, selection and fitting method. Interchangeable method requires high-precision processing, applicable to simple valves; selection and repair method through the economic precision machining after adjusting the compensation parts to improve the assembly efficiency and adaptability, commonly used in complex valves.

The 1,800 MW photovoltaic power project in Mangkang Angdo, Tibet, is currently the world's largest photovoltaic project under construction and at the highest altitude. It is expected to be connected to the grid by the end of 2025, with an annual power output of about 5.4 billion kWh, which is of great significance to the realisation of the ‘double-carbon’ target and the construction of the national demonstration base for the integration of water and wind power.

Safety valve design, discharge holes to ensure that the media does not accumulate, affecting the performance; drain holes to ensure that the bellows cavity ventilation, to avoid leakage of media; adjusting screw to regulate the opening pressure, to ensure safety. The three together to ensure the stable operation of the safety valve.

American Standard globe valve relies on its unique forced sealing structure, which achieves a tight fit through stem pressure and wedge sealing mechanism, and at the same time has a self-cleaning function to keep the sealing surface clean. Wear-resistant and corrosion-resistant materials are used and rigorously tested to ensure stable and reliable sealing performance.
