fluorine-lined check valve
Other Products
I. Introduction:
The H42F46 lined check valve mainly uses a rubber disc as the valve disc. Under the action of the medium, it can roll up, down, left and right on the integral slideway inside the valve body, thereby opening or closing the valve. It features silent closing without water hammer and good sealing performance. The valve body adopts a full flow channel, resulting in large flow rate, low resistance, and head loss 50% less than that of swing check valves. It can be installed horizontally or vertically, and is suitable for cold water, hot water, industrial and domestic water pipeline systems. It is especially adaptable to submersible sewage pumps, with a medium temperature range of 0 to 150°C. A check valve is a valve that automatically prevents fluid backflow. Its 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 disc automatically closes under the combined effects of fluid pressure difference and its own gravity, preventing fluid backflow.
