What is Valve? Usage Areas of Valves Valve, Flex Hose, PPR Pipe Blog What is Valve? Usage Areas of Valves Valve can be defined as a device or tool that moves between two pipes to stop the flow of water and similar fluids in the pipe, change the flow direction or release it. Often, in systems where fluid pressure is important, it is a device that reduces the pressure in the case of an increase in pressure or cuts off the connection of the pressure flow in dangerous situations. The valves, which are used today, do not just control fluid flow. They control flow, pressure, direction and gas, sludge or dry materials passing through the pipe. Valves can be produced in different sizes and different materials for various purposes. The valves are divided into types as radiator valves, solenoid valves, chiber valves, ball valves, thermostatic radiator valves, flanged valves. Valves are widely used today. Valves can be used up to temperatures down to -270 ° C and a pressure of 7000 bar, depending on the valve type. Valves can be flanged, threaded or welded in terms of connection. Most of the valves used today are manually operated. There are also valves used with mechanical and gear mechanisms. Valves are obtained by forging or casting from billet materials and then by welding two or more materials together. Most of the parts in their bodies are added during the production phase, and sometimes there may be parts added to the body later. How is the valve produced? Valves can be produced in any desired diameter and from various materials. Valves can control all fluids, from gases to high-impact chemicals, steam, toxic gases and radioactive materials. They can operate from very low temperatures to the highest temperatures, from vacuum pressures to hundreds of bar high pressure conditions. The valve varies according to pipe diameters, system structure and system pressure. Usage Areas of Valves Food facilities Ship building Natural gas line Heating and cooling lines Paper mills Water and waste water facilities Air handling units Fire extinguishing installations Energy stations Chemical and petrochemical facilities Gas and exhaust lines Piping installations Sanitary installations Engineering projects Water facilities Classification of Valves Valves by Flow Shape Shut-off Valves: It controls whether the flow in the installation is at the desired rate and place. It controls the progress or obstruction of the flow. Throttle and Control Valves: It is used to change the pressure or to adjust it at the desired level. These valves regulate the flow rate or temperature of the flow. Valves by Connection Type Screw valves Flanged valves Welding connection valves Compression valves Union-connection valves Valves with clamp connection Connection valves with brazing Valves by Material Used Valves with Metal material Valves with Elastomer material Valves with Thermoplastic material Valves by Body Shape One-piece valves Two-piece valves Three-piece valves Multi-piece valves Valves by Usage Functions Temperature adjustment Drainage Pressure adjustment Mixing Level adjustment Closing Flow rate adjustment Pressure reduction Valve parts Body: It is the part that contains the materials that allow the passage of the fluid and the sealing process takes place. The body guides and connects the fluid within the pipe. Cover: It is the part that provides the opening and closing process by being attached to the body. It facilitates the assembly of many parts attached to the body. Opening and Closing Spindle: It transmits the opening and closing process applied to the valve from outside to the closing part. On-Off Shaft Seal: It prevents leakage between the parts inside the valve. Closing Organ: Affects the flow in the valve. Actuator: It transmits the movement applied to the closing body, thus automatic opening or closing settings are made. How Quality Valves Should Be The materials inside determine the quality of the valve used. Valves are mostly made of stainless steel and copper alloy materials. Stainless valves are used in more than one place in an installation. Stainless valves can be interconnected in different ways. Stainless valves are divided into different models and classes according to their types. These; The butterfly valve Needle valve Ball valve Socket valve Flanged valve Monoblock valve Gate valve Knife valve Globe valve Mini ball valve Stainless valve types are divided into two classes in terms of quality. These; It is 304 quality valve and 316 quality valve. 304 Quality Valve: It is mostly used in liquid and fluid groups. Thanks to its low carbon and low chromium structure, 304 valves have a lot of usage areas. It consists of materials belonging to the austenite stainless steel class with 18% chromium and 8% nickel content. 316 Quality Valve: It is mostly used in lines where chemical flow is provided. 316 Quality valves carry out the transfer process in the flow of materials such as sea water and oil, which have high abrasion power. These valves are produced from materials with very high iron and chromium ratios. Stainless Steel Threaded Ball Valve These valves are generally used in flows where the pressure is 16-100 Bar. In these valves, flows are transferred across the pierced balls. Stainless threaded valves are divided into 2 and 3 parts according to the number of parts of their bodies. Stainless Butterfly Valve Stainless butterfly valves are mostly used in lines found in food and chemical plants. The lines in which these valves are installed must be very hygienic and therefore they are used with hygienic fittings. Stainless Flanged Valve Their operation is similar to ball valves, but flanged valves are mostly used in pressures that ball valves cannot withstand. Flanged valves are used in areas where the pressure is very high. Copper Alloy Valves It is used in air with high pressure in hot and cold water installations and in flow systems that do not have abrasive properties.
