The Importance of Industrial Valves Valves, although not stellar by industry. But it is the most important factor. A valve, each with different functions and features. Before deciding whether to use the valve to the valve must be aware that we are going to do anything. We have to assume the duties of each valve.                   1. Do not turn off (On-off service).          2. To control the flow rate (Throttling service).          3. Do not get the flow back (Prevention of back flow).                   Industrial fluids are involved in many different styles. They may be a liquid waste containing suspended solids are everywhere. As they are highly corrosive chemicals. The main characteristics of these must be taken into consideration, that is. Viscosity, and corrosion. The minutiae that must be considered is that the valve is related to only one type or several types of liquids. Much fluid pressure. Higher temperatures such as temperatures and corrosive influences the material used to make the valve or valves lining (Lining) lining material used in such valves are made from a plastic resin. To prevent the corrosion. The valves are made of cast iron or steel to withstand heat and high pressure valve has a small (4 inches) and usually made of brass or                   Tagbronss If large or with a high-pressure cast iron is used instead. Pressure drop (pressure drop) in the valve is very important. The numbers are not small compared with the pressure reducing valve that allows the system to select the type of low pressure drop is the best thing that can save the energy of the pump significantly.
