Gansu Hongfeng Machinery Co., Ltd., located in Pingliang City, Gansu Province, is a high-tech enterprise restructured and reorganized from the large-scale second-class military enterprise, the state-owned 920 Factory. It specializes in the research, development, and manufacturing of energy-saving products such as drain valves and condensate water recovery devices.
In the course of specializing in the production of energy-saving products and energy-saving devices such as traps and condensate recovery devices, "Hongfeng" takes the revitalization of the national equipment manufacturing industry and the creation of a national brand of traps as its own responsibility, closely tracks the development trends of science and technology and production trends, adheres to the technological innovation strategy of "no one has me, no one has me, no one has me, and I am new", and has realized the transformation from technology introduction, reference and absorption to independent innovation and independent development.
Based on the strict requirements of the steam system for the reliability, stability, durability and safety of pump and valve equipment, the company has established a complete set of quality assurance and control systems including procurement management, production control, performance verification, quality inspection, after-sales service, etc., and wholeheartedly escorts high-quality products.
We always respect and love our customers, and regard them as friends and siblings, and dedicate perfect services with a grateful heart, because customers are the pillar and source of our career success.
Air Trap
During compressed air production, moist air is heated as it passes through the compressor. As the unsaturated vapor cools to a certain temperature, moisture condenses into droplets and is carried along with the compressed air. Additionally, lubricating oil used for compressor operation may also enter the air stream. These oil and water contaminants can lead to equipment issues and should be removed promptly. In such applications, air traps are used to help separate oil and water, supporting reliable equipment performance and helping maintain operating efficiency.
Natural Gas Trap
The natural gas trap is a fully automated, self?operating valve that uses float and lever balance principles to separate gas and liquid in natural gas production, and to automatically discharge accumulated water from storage tanks, with minimal leakage during operation. It adapts to a variety of operating conditions, helps purify wellhead gas, and effectively separates impurities, supporting energy efficiency and environmental protection.
Trap valves
The liquid drain valve operates based on the specific gravity or density difference between media, using resulting liquid level changes to actuate the valve disc for automatic discharge of heavier liquids while helping to prevent gas or lighter liquid from escaping. In various industrial applications, these valves are known by different names—such as drain valves, liquid drains, condensate drains, compressed air drain valves, automatic drain traps, water drain valves, and float-type drain valves—yet they share many commonalities in structure and function.
Drain Valve
A drain valve automatically discharges liquids of higher specific gravity while helping to prevent gas or lighter liquid from escaping. It operates continuously, opening when heavier liquid accumulates and closing when none is present. The valve is used in petroleum, chemical, food, papermaking, metallurgical, and related industries for separating heavier liquids or water from lighter liquids.
Sanitary traps
A sanitary steam trap is a thermostatic trap designed to discharge condensate from clean steam systems. This series is constructed of stainless steel, with the internal surface precision-polished to facilitate smooth media flow and corrosion resistance. The seamless body design helps inhibit bacterial accumulation, supporting hygienic quality and production safety of the end product.
