valve is used when the pipe diameter through which the fluid is
flowing is long enough.
Pharmaceutical industries usually have plants installed of medicines
where liquid flows at high temperature and medicines are manufactured. They also need valves for regulating their system. The preferred valve used in such areas is Diaphragm valve. It is used in food industry
too. A diaphragm valve is made up of plastic or sometimes steel. For
the performance of this valve it is provided with actuators for
example, Pneumatic Actuator. A Diaphragm valve can be operated
manually or automatic.
One very interesting kind of valve is a flush bottom valve. These are
called bottom discharge valves too. They are called flush bottom
because they are used to flush tank and so are placed on the bottom of the tank to be flushed.
