What is a Stop Check Valve?
A stop check
valve combines the features of both lift check valve and globe valve. Opening and closing of stop check
valve is essentially similar to lift check valve and globe type valve
respectively.
How does a stop Check Valve work ?
Stop check valve
has stem which, when closed, stops the
disk from coming off the seat and provides a tight seal preventing flow of
fluid across it.This tight sealing of stop check valve is similar to globe valve.
When the stem is operated to the open position, the valve operates as a
lift check valve. The stem is not connected to the disk and functions to close
the valve tightly or to limit the travel of the check valve disk in the open
direction.
Stop check valve
drawing must also be taken from supplier to have complete understanding of
valves parts .Stop check valve drawing also helps HVAC engineers during the maintenance
of valves.
