Ductile Cast Iron Ball Check Valve
What is ball check valve
Ball check valve is one of the best check valves used in sewage and drainage systems. In the process of use, the ball will roll with the water flow and constantly roll over the sealing surface, that is, it has a cleaning effect on the sealing surface. If there are debris bonded to the sealing surface, the ball will be the first time to remove it out, to ensure that the seal is effective. And the ball valve in the use of the process of uniform force, solid structure, more difficult to damage.
Ductile Cast Iron Ball Check Valve Features:
1.The rubber ball is made of hollow steel ball with good elastic rubber outside to ensure the sealing and reduce the damage to the piping system in the process of closing the valve
2.Long service life, stable operation, safety and reliability, and good sealing performance;
3.The resistance coefficient is small. Because it is a ball valve, water flows almost straight through the valve body;
4.The shock absorption effect is good, and the water quality is not strict.
