Valves are devices that control the flow
of liquids or gases in a system. Valves used in almost all industries
ranging from farming, water, chemical, food and beverage industries. We
never bother to give a thought to valves though they are a crucial part
for the successful and safe running of any system.
How are valves made?
Valves
have many parts which are made of plastic or metal. The outer part is
usually made of metal and is called the seat. This is usually a solid
outer casing which seats an inner soft seal made of plastic or rubber
which ensures tight closure of the valve. The body is that part of the
valve which opens or closes the valve and snugly fits in the seat when
closed. The opening and closing of the valve is a mechanical movement
which is controlled by a lever, handwheel, faucet or an automated
mechanism.
What material is used to make valves?
The
Valve body is generally constructed from bronze, brass, iron, stainless
steel or plastic. The valve may be made from one material or a
combination of materials. The trim that is exposed to the flow media is
made from material that is resistant to the corrosion due to the flow
media.
Classification of valves
Valves
can be classified as per their design and functions. They can also be
classified as per the material that is used for construction, the end
connection or the temperature-pressure rating. The valve is stated by
the NPS (nominal pipe size) which must match the NPS of the line in
which it is to be connected.
Every
material has a pressure limit and temperature limit according to which
various valves are designed for various purposes. If the valve is
exposed to pressure or temperature that exceeds the limit specified in
the manual, the valve will not function efficiently.
Working of safety valves
Valves
are used in systems that contain flammable liquids, toxic chemicals,
high pressure steam, compressed air or such contents that cannot be
allowed to escape. Valves are controlled manually or automatically. A
closed valve should not let any liquid or gas escape or flow through
once it is closed. Pressure builds up in the container due to change in
temperature, movement or storage. Any increase in pressure may lead to
the catastrophic bursting of the container/cylinder which causes loss of
life and property. A safety valve that is used in these systems,
automatically opens to release the pressure inside the container thereby
prevent explosion.

system. JTC valve sales is the leading stockist for best quality industrial gas valves that are manufactured by Sherwood and Rego. The different types of valves are:
