Available Options
DN40 wafer type ball valves are made of stainless steel (SS) and are designed for full port flow. The diameter of the ball and the flow path are the same size, minimizing friction and pressure drop. Wafer style ball valve can be operated manually, with levers or gears, or automated using electric or pneumatic actuators for remote or automated control.

Tips: What is the best material for a ball valve?
The best material for a ball valve depends on the specific application and the media it will be handling. Common materials include stainless steel, brass, bronze, and PVC. Stainless steel is preferred for corrosive environments, offering excellent corrosion resistance. Brass and bronze are suitable for general-purpose applications, providing good durability and resistance to corrosion. PVC is preferred for applications involving water and other non-corrosive fluids, as it is lightweight and resistant to chemical corrosion. Additionally, materials like alloy steels or exotic alloys may be chosen for extreme conditions. It's crucial to consider factors such as temperature, pressure, and the nature of the fluid when selecting the ball valve material to ensure optimal performance and longevity.
