1.Stop-check valves are best suited for low to moderate velocity
applications. Correct sizing of stop-check valves is important.
Either too low a line velocity or too high a velocity can
damage valve internals and shorten valve life.
2.Service in systems involving frequent flow reversals and
pulsation should be avoided. Stop-check valves should be located
as far away from equipment such as pumps and compressors as
possible. Suspected problem systems should be reviewed with
Pacific Valves before selecting and purchasing stop-check
valves.
Threaded seat rings in valves in services with high velocity
(turbulent) flow or thermal cycling should be lock welded
to the body to avoid loosening. Please specify.
LIMITATIONS:
1.Globe pattern stop-check valves can be used in horizontal
piperuns with the stem straight up.
