BRASS NPT HORIZONTAL CHECK VALVE BRASS NPT HORIZONTAL CHECK VALVE is a safety valve used to control the flow of fluids in pipelines to prevent backflow and leakage. It is commonly used in wastewater treatment, chemical, food processing, petrochemical and other industries. And it is used with a wide variety of fluids including, but not to water, oil, gas, air, biodiesel, and fuels. PRINCIPLE OF CHECK VALVE When the fluid in the forward movement process, the valve flap by the fluid pressure will be pushed open, the fluid will be smooth through the pipeline into the next process. However, when the fluid flows in the reverse direction, the valve flap and the valve seat closely fit, preventing the reverse flow of the medium and leakage. CHECK VALVE WORKFLOW When the check valve is in normal working condition, the valve flap is in the open state, and the fluid can flow through unhindered. When the fluid flows in the reverse direction, the valve flap closes quickly, avoiding the backflow of fluid and preventing the leakage of the medium in the pipeline, which ensures the safety and stability of the pipeline to the environment.
