•
can be used for on and off service or throttling
•
when positive shut-off is necessary
•
where a low valve profile is necessary
•
only 90° rotation from open to fully closed (quick opening)
•
Handle position is a quick indication of whether valve is open
or closed.
•
full port ball valves do not resist flow

•
where positive shut-off is necessary
•
primarily for fully open or fully closed applications
•
may be used for throttling
•
only 90° rotation from open to fully closed
•
lightweight
•
easy to install
•
less costly than an iron body gate valve
•
for fully open or fully closed service - not for throttling
•
for minimum line pressure drop
•
for minimum fluid entrapment in the line
•
for relatively infrequent operation
•
To control the direction of flow and for quick, automatic
reactions to flow change. Swing check valves are used
when a minimum resistance to flow is required.
•
Swing check valves are recommended for use in
conjunction with gate valves. They should not be used in a
rapid recycling system such as reciprocating pumps or air
compressor service where they could cause chatter and
damaging vibration.
•
for regulation (throttling) of flow
•
for frequent operation; short stem travel reduces operator's
time
•
where some line resistance is acceptable
