Description

Flap Type Check Valve Manufacturers in India. In industrial fluid systems, preventing reverse flow is critical to safeguard pumps, pipelines, and sensitive equipment. The Flap Type Check Valve from Flow-Tek Valves & Controls Inc offers a simple yet highly effective solution. Its hinged disc (“flap”) responds instantly to fluid pressure, ensuring seamless forward flow while blocking backflow automatically. Technical Specifications & Build Quality Flow-Tek Valves & Controls Inc manufactures high-quality Flap Type Check Valves designed to meet stringent industrial standards (API, BS, DIN). • Size Range: 2' to 24' (Higher sizes available on request) • Pressure Rating: PN10, PN16, Class 150, Class 300 • Body Material: Cast Iron, Ductile Iron, WCB, Stainless Steel • Seating: EPDM/NBR (Resilient) or Metal-to-Metal • End Connections: Flanged, Wafer, Threaded How the Flap Type NRV Check Valve Works Forward Flow: When fluid flows in the intended direction, pressure lifts the flap, allowing an unobstructed passage with minimal resistance. Reverse Flow: As the flow stops or reverses, gravity or back pressure swings the flap back into the seated position, instantly sealing the valve. This quick response prevents backflow, protecting upstream equipment and pipelines from damage. Full-Port Design: The flap swings almost entirely out of the flow path, minimizing pressure drop compared to lift-type valves. Key Benefits : • Debris Management: Handles fluids containing suspended solids without clogging. • Reduced Water Hammer: Flap geometry cushions closure, minimizing shockwaves in piping systems. • Low Maintenance: Rugged hinge and few moving parts ensure years of reliable operation. • Versatile Applications: Suitable for a wide range of industrial, municipal, and agricultural systems. Industrial Applications Water & Wastewater Treatment: Prevents sewage backflow in lift stations, lagoons, and pumping stations. Chemical Processing: Provides reliable backflow prevention in lines handling corrosive or hazardous fluids. Agriculture & Irrigation: Ideal for pump outlets in ponds and tanks to maintain prime and prevent drainage. Power Generation: Used in cooling water and thermal management systems to ensure consistent flow and safety. Whether managing municipal drainage or high-pressure industrial pumping systems, the Flap Type Check Valve is an essential component for operational safety and efficiency.
