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.

1.Discharge temperature is adjustable during pipeline operation, effectively utilizing sensible heat from high?temperature condensate for significant energy savings.
2.Resistant to water hammer and features excellent air venting performance.
3.Low noise level during operation, contributing to a better working environment.
4.At initial start?up, the valve opens fully to rapidly discharge low?temperature condensate and air, shortening equipment warm?up time.
5.Internal components are constructed of stainless steel for corrosion and cavitation resistance.
6.Compact design for convenient installation and maintenance.
7.Application: Suitable for steam mains, steam tracing lines, radiators, low?temperature heating tanks, jacketed kettles, heating systems, and related applications.
Operating Condition Adjustment
1.The product is factory?set for 5 bar steam pressure.
2.Online adjustment is available according to actual operating conditions and process requirements: Turn the adjusting plug clockwise to lower the discharge temperature and reduce valve opening until fully closed; turn counterclockwise to raise the discharge temperature and increase valve opening until steam is directly discharged.
3.Adjustment procedure: With steam supply maintained upstream of the trap, remove the valve cap, loosen the lock nut, and turn the adjusting screw with a screwdriver. After adjustment, tighten the lock nut first, then replace the valve cap.
