SVR Global is the famous Dual plate check valve manufacturer in USA. It is also known as double-disc check valve or dual-disc check valve, it allows fluid (liquid or gas) to flow in one direction while preventing backflow in the opposing direction. It is distinguished by its small size and light weight, which are attained by the closure mechanism being two hinged plates or discs. These are frequently utilized in many different applications and sectors where dependable backflow prevention is crucial. Two symmetrical plates or discs are fixed on hinges inside the valve body of these valves. These plates swing open to permit forward flow and automatically close to stop backflow when there is reverse flow.These valves are ideal for applications where space is limited since they are often lighter and more compact than conventional swing check valves.Many twin plate check valves have springs installed to help the plates close fast when the flow direction changes. This creates a tighter seal and lowers the possibility of water hammer.These can accommodate a range of flow rates, pressure ratings, and fluid kinds and are offered in a variety of sizes and materials. For a specific application to operate at its best, proper dimensions and selection are essential.
