Product Description

H12w Copper Vertical Check Valve

The H12W copper vertical check valve is a type of check valve where the valve disc slides along the vertical centerline of the valve body. The H12 threaded vertical check valve can be installed on both vertical and horizontal pipelines. While its fluid resistance coefficient is higher than that of a swing check valve, its sealing performance is better. It features high precision, an attractive appearance, a compact design, a spring mechanism, and can be installed vertically or horizontally. It is primarily used in pipeline systems to prevent backflow of media.
