A butterfly valve with a simple structure, perfect for long-term use.

The valve rod adopts an eccentric structure that does not pass through the rubber valve seat, resulting in reduced localized friction and fatigue on the rubber valve seat. Additionally, the valve box seat area is coated with hard chrome, ensuring stable sealing performance. The structure is also designed to be simple, making it ideal for long-term use. 【Features】 - The eccentric structure that does not allow the valve rod to pass through the rubber valve seat minimizes localized friction and fatigue on the rubber valve seat, and the simple design ensures safe long-term use. - The valve box seat area is coated with hard chrome, and the structure includes an O-ring type rubber valve seat on the valve body side, allowing the rubber valve seat to be pressed against the valve box seat area by fluid pressure, which reduces wear and fatigue on the rubber valve seat and provides balanced sealing. Furthermore, this structure improves sealing performance as the pressure increases. - The O-ring type rubber valve seat results in less resistance around the entire seat area, reducing the operating torque during closure, allowing for smooth opening and closing. - It is compatible with both vertical and horizontal configurations.
