Valvesonly is the foremost Super Duplex Check valve manufacturer in USA. Our reach extends to countries like Kenya, Morocco, Algeria, and Nigeria. The primary purpose of a Super Duplex Check Valve is to function as a unidirectional gate, effectively preventing the reversal of fluid flow within a pipeline once it has been pumped. Within this valve, two openings are strategically designed to ensure the continuous movement of fluids. This valve finds crucial applications in various systems, notably in condensate pumps and sump pumps, where its role is to safeguard against backflow.
When the pump is actively operating, the resulting pressure exerts force on the valve, causing it to open and enabling the smooth passage of water through the pipes. However, once the pump ceases its operation, the valve's weight comes into play, forcing it to close securely and maintain a tight seal with the rubber against the valve seat. Without the presence of this essential check valve, the inexorable force of gravity would compel the water to return to the reservoir, disrupting the intended flow dynamics.
