Minimum Controlled Flow/No-Flow Leakage
Internal leakage will vary from valve to valve and with the
pressure differential across the check. Approximate levels
are:
Pressure Drop
The curves below show the pressure drop through individual
flow passages. Curves labeled “metered flow/pressure
drop” refer to the pressure drop through only the passage
containing the flow control regulating orifice. Total valve
insertion loss is a value derived from graph 1 or 2 plus the
appropriate values of lines 1, 2 and 3 from graph 3.

Graph 1
Metered flow pressure drop.
Normal adjustment – “2”
models (see model code,
page 24).
Graph 2
Metered flow pressure drop.
Fine adjustment – “1” models
(see model code, page 24).
Graph 3
Free flow pressure drop across
check valve.
Note:
“Turn” or “Turns” on curves in graphs 1 and 2, above, refer to turn of
adjustment device from fully closed position.
