Highlight: Single disc wafer check valve
Product introduction:
Wafer-type single-disc check valves are valves that automatically prevent fluid backflow. The valve disc opens under the
action of fluid pressure, allowing fluid to flow from the inlet side to the outlet side. When the pressure on the inlet side is
lower than that on the outlet side, the valve disc automatically closes under the influence of factors such as fluid pressure
differential and its own gravity to prevent fluid backflow. They are mainly suitable for water supply systems, as well as
industrial sectors such as petroleum, chemical, and metallurgy, especially in places with installation space limitations.
