Flanged and wafer check valves
The modern type of non-return valves for industrial use - double-leaf and cast-iron flapper valves are wafer type by the type of installation in pipelines and devices. Their peculiarity is that they are attached to the pipeline not through holes along the perimeter for tightening bolts, but are clamped together with gaskets between the flanges existing in the pipeline, which greatly simplifies the installation of a check valve in the system. Structurally, wafer check valves are simple and reliable devices, and due to the wafer installation option, their further maintenance in case of need for replacement or dismantling is not particularly labor intensive. Flanged check valve 16kch9p Du 50mm cast iron is a representative of lifting type valves, developed in the middle of the twentieth century. The absence of a return spring of the shut-off assembly lays in the design of this check valve the likelihood of its sticking in the open position.
