Product Description
Check valve, also known as a non-return valve or one-way valve, is a mechanical device commonly used in fluid systems to allow the flow of fluids in one direction and prevent backflow. It consists of a valve body with an inlet and outlet, and a movable disk or ball that acts as a blocking element. The check valve operates based on the pressure difference across the valve.
When the pressure on the inlet side is higher than the outlet side, the disk or ball is pushed against the valve seat, allowing fluid to pass through. However, when the pressure on the outlet side becomes higher than the inlet side, the valve closes, preventing backward flow. This feature is crucial in preventing contamination and damage to pumps, equipment, and systems.
Check valves are widely used in various industries, including oil and gas, water treatment, plumbing, and power generation. Their simple design and reliable functionality make them essential components in ensuring the proper and efficient operation of fluid systems.
