A Complete Guide to Automatic Thermostatic Mixing Valves for Hot and Cold Water—Model Overview and Price List (Part 1)
Complete Catalog and Price List of Automatic Thermostatic Mixing Valves for Hot and Cold Water (1)
One, Mixer Product Introduction:
Chengde Longzhida Automatic constant temperature for hot and cold water Mixer This is a complementary device developed specifically for solar water heating systems and centralized hot water supply systems. Users can independently adjust the mixed-water temperature according to their actual needs. The desired temperature can be quickly reached and stabilized, ensuring a consistently constant water temperature and thereby eliminating the hassle of manual adjustments during bathing—such as wasting water and experiencing sudden temperature fluctuations. This truly achieves energy and water savings while providing a safe, comfortable, and convenient experience.
II. Mixer Product usage:
Mixer It can be widely used for constant-temperature water supply in hotels, restaurants, hospitals, schools, bathhouses, industrial plants and mines, and the textile dyeing industry.
Three, Mixer Working principle:
At Mixer At the mixing outlet of the valve body, a thermally sensitive element is installed. Utilizing the temperature-sensitive properties of this element, it drives the valve core within the valve body to move, thereby sealing or opening the inlets for cold and hot water. When cold water is sealed off, hot water is simultaneously opened. Once the temperature adjustment knob is set to a specific temperature, the ratio of cold to hot water entering the outlet automatically adjusts accordingly, ensuring that the outlet water temperature remains consistently stable. The temperature adjustment knob can be set arbitrarily between 32°C and 48°C, and the thermostatic mixing valve will automatically maintain the set outlet water temperature.

Longzhida Company Successfully Hosted the Victory Parade Commemorating the War of Resistance.
Today is a day that every Chinese person should solemnly remember—the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War.
On July 2, Chengde Longzhida Company held a meeting with the Sino-German Institute. After thorough discussions between the two sides, Mr. Bai, General Manager of Longzhida Company, and the faculty team from the Sino-German Institute reached a consensus: Longzhida Company officially entrusted the Sino-German Institute to carry out the design and R&D work for a new type of ultrasonic water meter.
On May 30, Longzhida Company successfully held an exceptionally meaningful event titled “Welcoming the Eighth ‘National Science and Technology Workers’ Day’: Promoting the Spirit of Scientists.”
