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.

On 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.

Recently, Lianggu Valve successfully delivered a batch of DN5000 electric vacuum butterfly valves for the Xinjiang 2*330MW coal-fired subcritical direct air-cooled heating steam turbine generator project, demonstrating the company's strong strength in the field of ultra-large diameter valve manufacturing.

Lianggu Valve Group recently successfully shipped several batches of its ultra-large DN3200 electric butterfly valves, which are being used in the circulating water system of the Guizhou Energy Water City 2×660,000-kilowatt coal-fired power generation project. This demonstrates Lianggu Valve's deep involvement in the ultra-large-scale power generation sector and demonstrates the company's technical strength and engineering service capabilities in high-end equipment manufacturing.

In the fiery July of 2025, we usher in the 104th anniversary of the founding of the great Communist Party of China. Lianggu Valve Group pays the highest respects to the great Communist Party of China!

With the development of China's coal chemical industry and natural gas liquefaction industry, the localization of key equipment required is gradually deepening. Although the 100,000 cubic meter air separation unit was successfully used in Shenhua Ning Coal, a large number of large-scale air separation units and LNG-equipped cryogenic pump valves have been imported for a long time. To this end, the China General Machinery Industry Association held a seminar in Beijing on November 17, inviting relevant leaders and experts from Hangzhou Oxygen Group and Sichuan Air Separation Group to introduce the market of air separation units and natural gas liquefaction units for pump valves. Requirements and technical requirements, and discuss with the technical leaders of the pump and valve companies present at the meeting.

Seeking higher quality development
Wenzhou City, Zhejiang Province encourages industry associations to participate in quality co-governance to promote industrial quality improvement
Just in November, Zhejiang Quality Supervision Bureau successively held two quality comparison conferences. In these two quality comparisons, the relevant industry associations in Wenzhou were active organizers. The Longwan District Electrical Appliances Association assisted in organizing and implementing the quality comparison activities of indoor lighting switches, and the Yueqing Circuit Breaker Association assisted in organizing and implementing the quality comparison activities of small circuit breakers. The relevant person in charge of the Supervision Department of the Zhejiang Provincial Quality Supervision Bureau said that because of the active participation of industry associations, the number of companies participating in the comparison was greater than before, and the results of the comparison in the industry were more efficient than before.
