Check Valves Selection Guide | Engineering360

Wafer check valves were designed as a smaller, less expensive option from lift and swing check valves. Wafer check valves are designed to fit between a set of flanges. The disc in disc check valves moves in a plane at right angles to the flow of the fluid, resisted by the spring that is held in place by the retainer.

PRV Installation Issue - Safety Relief Valve engineering

The Steam Generator is 10 t/h, and is coil type and not a shell-tube boiler. The SG does not have any steam space like normal shell-tube boiler, and has just a small steam separator. Further, it has internal mechanism to stop firing, when steam pressure reaches 11 barg. So its very very unlikely, the RV in question will ever see that pressure.
