FLAP VALVE (also called a check valve, swing valve, or clapper valve) is a mechanical device designed to control fluid flow in one direction, preventing backflow.
Allows fluid (liquid or gas) to pass through freely in the desired direction.
Automatically closes when flow reverses, relying on fluid pressure and gravity for operation.
Eliminates backflow-related issues like system damage, pressure loss, or contamination.
Simple structure with few moving parts, ensuring reliable performance and low maintenance.
No external power required – operates passively via fluid dynamics.
Wide compatibility with different fluids (water, oil, gas) and operating conditions (temperature, pressure).
Compact design, suitable for installation in pipelines, tanks, pumps, and drainage systems.
Water and wastewater treatment plants (sewage systems, drainage lines).
Industrial pipelines (chemical processing, oil and gas, HVAC systems).
Marine equipment (ship ballast tanks, bilge systems).
Residential and commercial plumbing (preventing backflow in water supply lines).
Pumps and compressors (protecting equipment from reverse flow damage).
