China Butterfly Valves Manufacturer for Bulk Orders

Butterfly valves control liquid and gas flow with precise throttling and reliable shutoff across a range of industrial applications. Zhuhai Kunjian is a China butterfly valves manufacturer who can supply such valves. Buyers from all over the world and all industries can share their requirements. All they need to do is share specifications and objectives; our team will guide accordingly. We have compatible butterfly valves that contribute to higher efficiency and productivity.  

Certified China Butterfly Valves Manufacturer

Zhuhai Kunjian Technology Co., Ltd. is a direct manufacturer from China. We perform quality testing in numerous ways in our China butterfly valves factory. Our inspection team conducts physical and chemical tests on all valves. These inspections help us detect flaws such as internal fractures, etc. You can trust our quality regarding global standards compliance. We have ISO 5752, ISO 45001:2018, ASME B16.34, GB/T 19022-2003/ISO 10012:2003, and API 609 certifications to ensure compatibility with international industrial requirements. 

Less Risk of Turbulence, Noise, Vibration, and Cavitation

These units excel in high-turbulence environments where pressure stability is critical. We work on all the possible challenges these bulk butterfly valves could face. Therefore, you can expect them to resist turbulence, noise, and vibration. Our valves achieve noise levels below 80 dB in standard operating conditions, minimizing downstream equipment wear. Even if you are expecting them to resist cavitation, they will meet your requirements. These valves will resist maximum cavitation. For medium-temperature applications requiring durability and reliability, these deliver proven performance. When these valves resist these challenges, there will be better durability. This durability makes our quality more compatible with every industrial valve system

Butterfly Valve Sizes, Pressure Ratings, and Actuation Options  

Our butterfly valves are well suited for large-diameter pipes, especially in installations where space is limited. Their compact, narrow design takes up less room while helping reduce installation costs. This makes them a practical choice for industries looking for efficient installation, reliable flow control, and better use of available space.

We have a size range from DN 50 to DN 1200 (2" to 48"). This means we can meet the requirements of almost every industry for precise results. Even if you want a precise pressure rating, we can help you with that. We have options like PN 10, PN 16, class 150, etc. 

We offer a range of body and shell materials to suit different application requirements. Our China butterfly valves factory produces valves in ductile iron (GGG40/50), cast steel (WCB), and stainless steel (CF8/CF8M). This allows industrial buyers to choose the material that best matches their operating conditions and compatibility needs. We also offer different actuation options, including manual lever, worm gear, pneumatic, and electric. For other shutoff requirements, buyers can also explore our ball valve options.

Reliable Sealing for Harsh Fluids and Slurries

All the butterfly valves we supply have one thing in common, that is excellent sealing. All of them have heavy-duty seats that ensure there are excellent sealing properties. This is why we provide options in seat materials like EPDM, NBR, VITON, and PTFE. As a result, there will always be consistently tight sealing in every valve. Industries like chemical, food, beverage, petrochemical, and wastewater treatment plants can choose us. Our butterfly valves can withstand low-corrosive slurries, harsh liquids, and similar challenges. Due to this property, there will be low pressure drop and high flow consistency in each butterfly valve.
