RE: CHECK VALVES
pumps and fluids, hight velocity systems, flow must
be sufficient to keep the valve open fully otherwise
it will cause damages and high pressure drop.
location these valve in system is critical and it
must be not less than five pipe diameters from elbows.
RE: CHECK VALVES
of valves especially when we use them with pumps
which can cause damage to pump .
these valves to my knowledge are normally designed
for installation in horizontal pipe runs or in vertical
lines where flow is up only.
i suggest to make sure the designed calculated with
safety factor to avoid that, maintain valve constanly,
make sure the pressure doesn`t drop and valve seat
maintain periodically.

RE: CHECK VALVES
When pump (and associate pipeline) is not running or operating, related isolation /block valves shall be closed. There was crude oil spill incident due to the oil leaked through check valves. It was happen because of equilibrium pressure in the line during no flow. Check valve does not function or no meaning when there is no flow or no pressure drop.
