Center cap type butterfly valve

A butterfly valve with performance equivalent to JWWA B 138 standards, featuring a structure where the operating cap is located at the center of the valve.

The butterfly valve meets the JWWA B 138 standard and has equivalent performance, while being lower in height compared to standard products. Additionally, the structure has the operating cap at the center of the valve, making the installation of the valve chamber easier. 【Features】 - It adopts an eccentric structure where the valve rod does not pass through the rubber valve seat, resulting in less localized friction and fatigue on the rubber valve seat, allowing for 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, ensuring that the rubber valve seat is pressed adequately against the valve box seat area by fluid pressure, which reduces wear and fatigue on the rubber valve seat and provides balanced sealing. This structure improves sealing performance as the pressure increases. - Since the rubber valve seat is of the O-ring type, there is less resistance around the entire seat area, which reduces the operating torque during closure, allowing for smooth opening and closing.
