1. It can be quickly cut off in the pipeline system, and the function of turning on the medium flow is the same as that of the ball valve.
2. The valve body has a built-in filter to effectively filter impurities in the water. Increase the drain water valve at the impurity accumulation. The cap at the drain is the handwheel that opens the stem of the pool valve. When the rod rotates counterclockwise, the medium in the pipe flows out of the drain, and the impurities accumulated on the filter net flow out of the drain with the medium. This process is the backwashing process. After draining the impurities, turn the valve stem clockwise to close the drain drain valve. Caps are placed at the mouth of the pool.
