Valve Solutions for the Coal Chemical Industry

The coal chemical industry faces multiple challenges in the process of converting coal into clean energy and synthetic oil. Coal-to-natural gas production is a crucial step, and leakage has consistently been a major challenge in the industry. Traditional valves often struggle to provide robust sealing performance when handling intense processes, extreme temperatures, or corrosive media. To address these issues, Tianyu Valve is dedicated to providing innovative valve solutions for the coal chemical industry.


In the coal chemical industry, coal gasification is a key production process that demands valves with wear resistance and suitability for the specific requirements of gasification. Tianyu Valve’s valve series is designed to meet these challenges. These valves not only handle the low working temperatures required for processes like air separation but also exhibit excellent sealing performance, effectively preventing leaks. This low leakage performance is particularly crucial when dealing with media that may contain toxic substances, ensuring the reliable containment of hazardous materials within the pipeline and maintaining process safety.

Tianyu Valve’s valve solutions find wide application in the coal chemical industry, encompassing coal-to-gas producers and manufacturers directly converting coal into liquefied gas. These valves not only possess high wear resistance and low-temperature capabilities but also resist corrosion in the media, ensuring the stability of the system.

The industrial valve series from Tianyu provides diverse solutions for the coal chemical industry, including gate valves, control valves, safety valves, and more, catering to different processes and applications. Our industrial valves adhere to international standards, including API 6D, API 609, CE, ISO900 etc., ensuring their design meets the highest industry standards. Tianyu Valve is committed to providing high-quality, high-performance valve solutions for the coal chemical industry. By meeting industry-specific needs, handling extreme conditions, and managing hazardous media, Tianyu Valve contributes to the industry’s sustainable and safe development.

Tianyu Valve’s valve solutions are designed to meet the specific requirements of the coal chemical industry, offering customers high-quality and reliable valve products and services. We will continue to innovate to adapt to the ever-evolving and changing landscape of the coal chemical industry.
