API 594 dual plate check valve is widely used in the flow control industry. Due to its short face-to-face dimension, it requires smaller installation space and has a lower weight, which offers competitive life cycles costs compared with the swing check valve.
Featuring a single inlet and outlet, check valves are operated by a pressure differential. Above a certain upstream pressure, the valve will automatically open without requiring any other intervention. Known as the cracking pressure, this minimum operational pressure is one of the key characteristics specified in all check valves. Chemicals, pulp and paper, food processing, water and wastewater treatment, industrial, marine and mining, pumps, pipelines, power generation and HVAC are among the many fluid flow and pumping applications that feature check valves.
