What is inflatable seat butterfly valve?
An inflatable butterfly valve, also known as an air-operated butterfly valve, is a type of valve that uses air pressure to operate. The valve consists of a butterfly disc mounted on a shaft inside a valve body. The disc is connected to an inflatable seal or bladder that is inflated or deflated with air pressure to open or close the valve. When the seal is inflated, it presses against the valve body and closes off the flow of fluid. The disc rotates when the seal is deflated to allow fluid to flow through the valve.
Inflatable butterfly valves are commonly used in applications requiring a tight, leak-proof seal, such as in water treatment, wastewater treatment, and chemical processing. They are often used when other valves may not provide a tight enough seal or may be prone to leakage. Inflatable butterfly valves are also useful in situations where manual or mechanical operation of valves is not feasible, such as in remote locations or hazardous environments. The air-operated system allows for easy and remote operation of the valve, making it a popular choice in many industries.
The inflatable seat butterfly valve is an innovative and reliable solution for controlling and regulating fluid flow in various industrial applications.

Advantages of inflatable butterfly valve!
1. Inflatable Seat Design
The inflatable seat design provides excellent sealing performance and reduces wear and tear on the valve components, ensuring long service life and low maintenance costs.
2. Wide Range of Sizes
Available in sizes ranging from DN50 to DN1000, the inflatable seat butterfly valve can accommodate a variety of pipeline diameters and flow rates.
3. Various Material Options
The valve is made from a selection of high-quality materials, including ASTM A536 65-45-12, WCB, CF8M for the body, and material options like Nylon-coated ASTM A536 65-45-12, CF8, CF8M, 2507, and 1.4462 for the disc. This ensures compatibility with different media and operating
conditions.
4. Multiple Seat Materials
The seat materials can be chosen from EPDM, NBR, FRM, or PTFE, providing flexibility and compatibility with various fluids and operating temperatures.
5. Stainless Steel Components
The valve’s stem, lower stem, retainer, nuts, and screws are made from corrosion-resistant stainless steel for durability and long-lasting performance.
6. Reliable, built to last
Before delivery, we make 100% test for each product to ensure its quality.
Features of inflatable seat butterfly valve：
The unique design of the expansion butterfly valve uses gas pressure to extend the valve seat toward the valve disc to provide a smooth distribution of pressure to the seal at all times. Since only momentary contact occurs between the valve disc and the valve seat during the opening and closing of the valve, the valve disc is only slightly bumped. On the contrary, for the general butterfly valve, the collision caused by the valve disc rubbing the valve seat will reduce the performance and life of the valve.
Case:
Pakistan Sewage Treatment Plant Project
Main products: Flanged Butterfly Valves and Gate Valves
This case is an old customer from Pakistan. Because he has purchased valve products from WESDOM many times, he has very high trust and evaluation on WESDOM. He needs a lot of butterfly valves and gate valve products in the sewage treatment plant project which he is responsible for. They sent the requirements to the businessman of WESDOM's international trade department without hesitation. Of course, WESDOM still returns this old customer in Pakistan with high-quality products and preferential prices;
After that, the customer also sent us the installation pictures of the WESDOM product in the working condition project, and feedback that the quality is still very good, and will maintain a long-term cooperative relationship with WESDOM;
