Automatic
control valves (or control nozzles) are basically small sized valves used in
gas or liquid services. Since this type of valve has a fly-threading stem, a
larger seat area will help you with a certain resistance flow. There are
different types of needle valves available in the market. These nozzles differ
in their size, function, shape etc.
Basically,
needle valves are used to control the flow of gases and liquids at low rates.
The large seat area of this valve and the finely threaded stem will help you with
a certain resistance to flow. Such a valve design is also used to control the
flow of fluid in a delicate gauge that can be damaged by a sudden increase in
fluid, which will remain at high pressure. The Automatic control Valve
is also the best option for working in high pressure conditions.
With
the help of needle nozzle and breather valve,
you also have the option to stop the flow. You can also make some specific
adjustments in this valve to maintain fluid flow. There are also needle valves
and hydraulic valves, which are obtained to control the flow of water.
Moreover, most of these valves do not require any additional power source for
operation.
