The operation of the wafer lug type butterfly valve is very flexible, and can achieve precise regulation of fluid flow through manual, pneumatic or electric drive. The valve disc controls the fluid switch by rotating, and can be fully opened or fully closed within a 90° rotation range. It responds quickly and is suitable for the flow management of a variety of fluid media. Its sealing design usually adopts elastic seals or metal seals to effectively prevent leakage and ensure the safety of the system.

Wafer design: The lug-type butterfly valve is clamped and installed through the lug structure on both sides. It can be directly clamped between flanges, avoiding the complex support structure of traditional valves, reducing installation time and cost, and is particularly suitable for pipeline systems in narrow spaces.
Excellent sealing performance: The valve adopts elastic sealing or metal sealing design to ensure no leakage during operation and improve the safety and reliability of the system. The selection of seals can be customized according to the characteristics of the medium to adapt to different working environments.
Easy operation: The butterfly plate of the valve adjusts the flow of the fluid by rotation. A 90° rotation can achieve full opening or full closing. The operation is simple and fast, suitable for the needs of fast switching and flow adjustment.

FAQ
1. How to install the wafer lug type butterfly valve?
This valve adopts a wafer design and can be directly clamped between the pipe flanges without additional support structure. This design makes the installation process fast and easy, suitable for pipeline systems with limited space.
2. What are the operating methods of the wafer lug butterfly valve?
Wafer lug butterfly valves usually support three driving modes: manual, pneumatic and electric. Manual operation is suitable for simple occasions, while pneumatic and electric drives are suitable for scenes that require fast response and remote control.
3. How to maintain the wafer lug type butterfly valve?
Regularly check the valve seals and valve stems, and clean impurities to avoid affecting the operating performance of the valve. If the seals are worn, they should be replaced in time. Cast iron valve bodies are generally not recommended for highly corrosive media environments.
