A Dual Plate Check Valve operates automatically, using the flow pressure of the medium to control the opening and closing of its two spring-loaded plates. When fluid flows in the forward direction, pressure...
Read moreCracking pressure is a critical parameter in check valves because it determines the minimum upstream pressure required for the valve to begin opening and allow flow. By defining exactly when the valve...
Read moreThe primary purpose of installing a dual plate check valve is to prevent reverse flow and protect system components. When fluid flows in the forward direction, the plates open automatically; when reverse...
Read moreThe flow coefficient (Cv) and its metric equivalent (Kv) are essential parameters that define the flow performance and pressure characteristics of a valve. These values are calculated according to the ISA–S75.01–1985...
Read moreThe pressure and temperature ratings of the dual plate check valve shall comply with the values specified in ASME B16.34, according to the applicable material specifications, class designations, and pressure...
Read moreValve Sticking: Particles may become trapped between the valve disc and the sealing surface, affecting the valve’s normal operation and potentially preventing it from fully closing. Seal Damage: Particles...
Read moreWhen two or more pumps or blowers are installed in parallel, check valves are used to isolate the ones that are not operating. In some applications, backflow is detrimental to the process or to equipment...
Read moreThe optimal installation distance of 6 to 8 pipe diameters for components such as check valves in piping systems is based on fluid dynamics and flow behavior within pipes. This distance is considered ideal....
