Featuring advanced soft sealing technology with rubber and PTFE materials, this valve ensures leak-proof performance and contamination-free operation, making it ideal for industries requiring high hygiene standards. Compliant with GB Standard (GB/12238, GB/12221), it offers a wide range of nominal diameters (DN50 ~ DN800) and compatible pneumatic actuators (GT Series, AT Series, AW Series) for flexible control. Crafted with materials like balloon iron (hard chrome-plated), carbon steel, and stainless steel, the valve balances durability, corrosion resistance, and easy maintenance. Whether for food processing, pharmaceutical production, or municipal water supply, this soft sealing butterfly valve delivers efficient, reliable flow management with minimal operational downtime.

Utilizing PTFE and rubber seals, the valve achieves zero leakage even at low pressures, preventing media contamination and ensuring environmental safety—critical for hygienic applications.
Optimized for PN6 and PN10 (0.6MPa ~ 1.0MPa) operating pressures, the valve delivers smooth flow control with minimal pressure drop, reducing energy consumption in low-pressure systems.
Materials like stainless steel and hard chrome-plated ductile iron resist corrosion from chemicals, water, and mild acids, extending service life in harsh or hygienic environments.
Smooth internal surfaces and non-toxic sealing materials (PTFE, food-grade rubber) meet hygiene standards, making the valve suitable for food, beverage, and pharmaceutical applications.
Lightweight construction, standard flange connections, and accessible components simplify installation, disassembly, and maintenance, reducing operational costs.
Compatible with GT Series, AT Series, and AW Series pneumatic actuators, the valve offers flexible control options for different automation needs, ensuring precise and responsive operation.
Ideal for controlling the flow of juices, dairy products, sauces, and processed foods, with hygienic seals and materials that meet FDA standards.
Used in drug production and packaging lines, where contamination-free operation and reliable sealing are critical for product quality.
Suitable for municipal water treatment plants, residential water supply, and wastewater systems, offering leak-proof performance and corrosion resistance.
Applied in heating, ventilation, and air conditioning systems for water and refrigerant flow control, ensuring energy-efficient operation.
Perfect for low-pressure chemical applications involving mild acids, alkalis, and solvents, with corrosion-resistant materials and secure sealing.
The valve uses high-performance sealing materials, including PTFE (polytetrafluoroethylene), rubber, and Viton (fluororubber), ensuring leak-proof and contamination-free operation.
The valve is rated for low pressures: PN6 (0.6MPa) and PN10 (1.0MPa), making it suitable for low-pressure systems like HVAC, water supply, and food processing.
Yes. The valve’s hygienic design, non-toxic seals (PTFE, food-grade rubber), and smooth internal surfaces comply with hygiene standards, making it safe for food and pharmaceutical use.
The valve works seamlessly with GT Series, AT Series, and AW Series pneumatic actuators, supporting both manual and automated control setups.
Thanks to its durable materials and simple structure, the valve requires minimal maintenance. Routine checks of seals and actuators every 6–12 months are recommended for optimal performance.
Note: The structural length and connecting flange size of butterfly valve series can be designed and manufactured as per users' requirements.
Note: The main spare parts and sealing-ring materials of butterfly valve series can be designed
