DUAL PLATE CHECK VALVE
“aline” Make Dual Plate Check Valve – Wafer Type / Flanged End is engineered to provide reliable backflow prevention in industrial piping systems while minimizing pressure loss and eliminating water hammer. Designed with two spring-loaded semicircular plates, the valve closes rapidly upon flow reversal, ensuring smooth operation and protecting pumps, compressors, and pipelines from reverse flow damage.
Its compact wafer design allows installation between standard pipeline flanges, while the flanged end version offers a robust and secure connection for heavy-duty applications. Manufactured from premium-quality materials with precision engineering, the valve delivers excellent sealing performance, corrosion resistance, lightweight construction, and long service life.
The spring-assisted dual plate mechanism significantly reduces closing time, making it an ideal solution for high-flow and high-pressure systems where reliable non-return protection is essential. ALINE Dual Plate Check Valves are widely used in Water Treatment Plants, Oil & Gas Industries, Chemical Plants, Petrochemical Industries, Power Plants, Fire Fighting Systems, HVAC Systems, Marine Applications, Pharmaceutical Industries, Food Processing, and General Industrial Process Pipelines.
Built for dependable performance and low maintenance, the ALINE Dual Plate Check Valve improves system efficiency while protecting valuable equipment from reverse flow and pressure surges.
