BNSV DIN F6 Ball Check Valve
Overview
The ball check valve is a short-stroke roll of the rubber ball in the valve body to realize the sealing opening and closing. When the water pump starts, the water reopens the rubber ball under pressure, so that the rubber ball rolls to the middle head, from the back to the middle head. The concave semicircle fixes its position. After the water is stopped, due to the backwater pressure in the pipeline, the rubber ball is forced to roll to the left valve body to achieve the effect of non-return closing.
1. It has features of long service life, stable operation, safe and reliable, and good sealing performance.
2. The drag coefficient is small. Due to the angle design, the water flow almost directly passes through the valve body.
3. The shock absorption effect is good, and the water quality requirements are not strict.
