High Performance Butterfly Valve

Product Introduction

High-performance butterfly valves adopt advanced sealing technology, such as flexible lip seat structure, etc. This sealing structure is designed with good elasticity and reliable sealing, and can compensate for changes in temperature and pressure to ensure that the valve can maintain excellent sealing effect under different working conditions‌.

Product Advantages

1. High-performance butterfly valves are usually sealed with sealing rings and elastic materials. The butterfly valve of this structure has a small contact area with the sealing material during opening and closing, so the wear rate is also low and the sealing performance is longer lasting.

2. High-performance butterfly valves are usually made of high-strength, high-corrosion-resistant materials. These materials can effectively resist corrosion and oxidation and extend its service life.

3. The high-performance butterfly valve adopts an eccentric structure design to reduce the friction of the sealing ring and extend the service life of the valve. In addition, the seat design of the high-performance butterfly valve features a polymer composite for unlimited life expectancy and very high chemical resistance‌.

4. The operating force of high-performance butterfly valves is usually low, and only a slight rotation is needed to open and close. This feature makes it easier to operate and is especially suitable for frequent opening and closing applications, while also reducing personnel fatigue and maintenance costs associated with operating valves‌.

5. High-performance butterfly valves mainly include double eccentric high-performance butterfly valves, stainless steel high-performance butterfly valves, pneumatic high-performance butterfly valves, and electric high-performance butterfly valves.

• The high-performance butterfly valve is made of polytetrafluoroethylene (PTFE) or metal sealing material, double eccentric butterfly plates with spherical sealing surfaces, and a flexible lip structure of valve seat, which can achieve two-way zero-leakage sealing and ensure that it can maintain excellent sealing performance under various working conditions‌.

• The design life of the high-performance butterfly valve can reach more than 1 million times, with smaller torque and longer service life. It is suitable for frequent opening and closing conditions‌.

• High-performance butterfly valves are suitable for a variety of media and working conditions, and can work stably in high temperature, high pressure, vacuum and other environments‌.

• The valve seat is designed as a movable insert (seat insert), which is easy to replace. Just remove the insert to take out the valve seat. There is no need to disassemble the valve plate and valve shaft, reducing maintenance difficulty‌‌.
