????? (Valves)

  ?????????
• ????????? Glove valve, Angle valve, Gate valve,
  Check valve, Pressure Reducing Valve, Safety valve

22

Globe valves are used primarily in situations
where throttling of the commodity is required.
23

• The gate valve is the most frequently used valve
  in piping systems.
• When fully opened, the gate valve creates
  minimal obstruction to the flow.

26

The angle valve, like the globe valve, is used
for throttling. The flow entering the valve
and the flow leaving the valve form a 90O angle.
27

Check valves differ significantly from gate and
globe valves. Check valves are designed to
prevent backflow.
28

The ball valve is an inexpensive alternative to
other valves. Ball valves use a metal ball with
a hole bored through the center, sandwiched
between two seats to control flow.
29

Relief valves have a purpose quite different from
the previous valves. They are designed to release
excessive pressure that builds up in equipment
and piping systems.
30

The control valve is an automated valve that can
make precise adjustments to regulate and monitor
any commodity flowing through a piping system.
31

The butterfly uses a circular plate or wafer
operated by a wrench to control flow. A 90O turn
of the wrench moves the wafer from a fully open
position to a fully closed position.
