● Dual Sealing Structure: Equipped with a double-gate design, each gate features an independent sealing system to completely isolate the medium during sampling, eliminating the risk of leakage.
● Bidirectional Sealing Function: The valve provides sealing in both forward and reverse directions, effectively preventing backflow of the medium and ensuring the accuracy and safety of sampling.
● High Corrosion Resistance: The valve body and key components are made of high-quality corrosion-resistant materials, suitable for various acidic and alkaline media environments, extending service life.
● Easy Operation: Available with manual or electric actuation, the valve offers flexible operation and can quickly complete sampling tasks, improving work efficiency.
● Precise Sampling: The valve design ensures stable sampling flow, avoiding media fluctuations and meeting high-precision sampling requirements.
● Convenient Maintenance: With a compact structure that is easy to disassemble and maintain, it reduces maintenance costs and downtime.
● The Double Gate Sampling Valve is widely used in industries such as chemical, pharmaceutical, and food, making it an ideal choice for safe and efficient sampling.

An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
Self-operated Temperature Regulator is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
