Technical Specifications • Valve Type: Swing Type Check Non-Return Valve • Body Design: Wafer / Flanged • Disc Type: Hinged Swing Disc • Seat Options: Metal Seat, Viton Seat Rings, Hard Surface Seat • Lining Options: Rubber Lined (for corrosive services) • Material: Cast Iron, Stainless Steel, Lined Construction • Temperature Range: Suitable for high-temperature applications • Media: Water, oil, gas, chemicals, sewage, and other fluids • Operation: Automatic (no external power required) How Swing Type Check Non-Return Valves Work The Swing Type Check Valve operates automatically using a hinged disc to control flow direction: • Forward Flow: Fluid pressure pushes the hinged disc open, allowing smooth flow with minimal resistance. • Reverse Flow: As pressure drops or reverses, the disc swings back onto the seat, sealing the valve instantly and preventing backflow. This automatic design requires no external power, making it ideal for pipelines handling water, gases, chemicals, and other fluids under variable flow conditions. Key Features & Construction 1. Robust Disc Mechanism: Hinged disc ensures reliable unidirectional flow with minimal wear. 2. Material Versatility: Cast Iron, Stainless Steel, and Rubber Lined options for corrosive or abrasive media. 3. Precision Sealing: Viton seat rings and hard surface seating deliver long service life and leak-tight performance. 4. High Temperature Resistance: Suitable for demanding high-temp industrial systems. 5. Design Flexibility: Wafer and flanged configurations with optional damping to prevent disc slamming.
