Description
Note: This ball valve cannot be used for drinking water.
15mm wafer type ball valve is a type of quarter-turn valve with a full port design that indicates the bore of the ball is larger, minimizing flow restrictions and maximizing flow capacity.

Tips: Difference between wafer ball valve and wafer check valve
A wafer ball valve and a wafer check valve serve distinct purposes in fluid control systems. A wafer ball valve is primarily designed for on/off control of flow, utilizing a rotating ball to open or close the passage. It offers low resistance to fluid flow when fully open, making it suitable for quick and efficient isolation.
A wafer check valve is engineered to prevent backflow in pipelines. It features a hinged or spring-loaded disc that allows fluid to flow in one direction while blocking reverse flow. The wafer check valve is often employed to safeguard pumps and other equipment from damage caused by backflow. Unlike the ball valve, the check valve operates automatically, responding to changes in flow direction without manual intervention. In summary, the wafer ball valve is geared towards flow regulation, while the wafer check valve prioritizes preventing backflow in a pipeline.
