Founded in 2014 and based in the Beichen District valve manufacturing cluster of Tianjin, China, Tianjin Liangfa Technology Co., Ltd. has focused on butterfly valve development and manufacturing for more than a decade. The company has expanded its product range to include ball valves, gate valves, and check valves while continuously improving its manufacturing, quality inspection, and technical support capabilities. Recognized as a National High-Tech Enterprise and a Specialized and Sophisticated SME, Liangfa is committed to supplying reliable industrial valves and practical fluid control solutions for customers across various industries.

From Butterfly Valve Manufacturing to a Broader Product Range

Tianjin Liangfa Technology was established in 2014 with a registered capital of RMB 25.8 million. Leveraging the established valve manufacturing supply chain in Tianjin's Beichen District, the company initially focused on standardized industrial butterfly valve production.

In its early stages, Liangfa concentrated on products such as worm gear wafer butterfly valves and soft-seated wafer butterfly valves. By emphasizing casting quality, machining accuracy, sealing component compatibility, and standardized production procedures, the company gradually expanded into municipal water supply and drainage projects as well as small and medium-sized chemical applications.

As industrial fluid control requirements became more diverse, Liangfa continued to expand beyond standard butterfly valves. Its product development gradually extended to automated valve solutions, customized products, and valves designed for specialized operating conditions, strengthening its ability to meet different project requirements.

Advancing Electric and Pneumatic Butterfly Valve Manufacturing

In 2018, Liangfa upgraded its manufacturing facilities by expanding its standardized production workshops and developing dedicated production lines for electric and pneumatic actuators. This initiative strengthened the company's ability to integrate butterfly valve bodies with their driving mechanisms.

By improving the coordination of valve bodies, actuators, and sealing components, Liangfa enhanced its assembly and product matching capabilities. Integrated production and assembly can help reduce compatibility issues, simplify procurement coordination, and improve delivery efficiency.

Electric butterfly valves and pneumatic butterfly valves have since become important product categories. Depending on their configuration, these valves can support automated opening and closing, centralized control, and integration into industrial process systems. They are suitable for applications that require automated valve operation, including selected power generation, environmental protection, and industrial automation projects.

Strengthening Quality Control Through Professional Testing

Industrial valves operate under different pressure, temperature, and media conditions, making material quality, structural integrity, and sealing performance critical to reliable operation. In 2021, Tianjin Liangfa Technology established a professional physical and chemical testing center covering approximately 2,000 square meters.

The facility is equipped with testing equipment for material and mechanical properties, sealing performance, high- and low-temperature testing, corrosion-related testing, and nondestructive inspection. These capabilities support the company's quality management processes, covering incoming material inspection, production control, and finished-product testing for butterfly valves, ball valves, gate valves, and check valves.

Testing procedures are selected according to the relevant product specifications and application requirements. This approach helps improve product consistency and provides a stronger basis for quality verification before delivery.

The testing infrastructure also supports customized valve development. For applications such as flue gas desulfurization, marine piping, high-temperature chemical processes, and fire protection systems, Liangfa can provide product selection and customization options based on the operating medium, temperature, pressure, and installation conditions.
