An Insight Into Industrial Gas Valves

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.

Valves and safety valves are integral for the safe and reliable working of any 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:
