On the road to achieving the "dual carbon" goal and building a green, low-carbon energy system, every process link and every technological breakthrough has become a key force driving the transformation of China's energy industry. As a key component of industrial safety protection, valves, though small, play a vital role.
ReadOn July 21, 2025, Gao Yonghong, Secretary of the Party Working Committee and Director of the Management Committee of Yangquan High-tech Zone, and Yang Yarong, Secretary of the Party Committee and Chairman of Yangquan Valve Co., Ltd., along with their delegation, thoroughly studied and understood the important speech delivered by General Secretary Xi Jinping during his inspection tour of Shanxi Province. The first stop of their study tour on high-quality development of the valve industry was at Lianggu Valve Group in Longwan District, Wenzhou, Zhejiang Province. Group Chairman Pan Chengtao, General Manager Pan Junxiang, and Chief Technical Engineer Qu Dehu, along with other group leaders, warmly welcomed the delegation and discussed the deep integration of the revitalization of traditional manufacturing with new-quality productivity, jointly writing a new chapter in the construction of a manufacturing powerhouse.
With the deepening implementation of the Belt and Road Initiative, Chinese manufacturing is serving an increasing number of key international projects with reliable quality and superior strength. Recently, Lianggu Valve Group successfully shipped high-voltage power station valves for the coal-fired power integration project in Block 1 of the Thar Coalfield in Pakistan, providing a solid valve protection solution for the project.
The 600MW (megawatt) unit steam extraction molten salt energy storage project in Hebei Province is the country's first thermal power side molten salt energy storage demonstration project. It has pioneered the technology of molten salt energy storage for thermal power extraction steam in China and opened up a new technical path for thermal power units to significantly improve their peak-shaving capacity.

Ball valve (ball valve), a valve that is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. The hard-sealed V-ball valve has a strong shear force between the V-shaped core and the metal valve seat of the hardfacing. It is especially suitable for fibers and small solid particles And other media. The multi-port ball valve can not only flexibly control the confluence, divergence, and flow direction of the medium on the pipeline, but also can close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valve is divided into pneumatic ball valve, electric ball valve and manual ball valve according to the driving mode.
The gate valve is a gate of the opening and closing piece. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel and so on. The gate has rigid gate and elastic gate. According to the different gates, the gate valve is divided into rigid gate valve and elastic gate valve.
