Taps and fittings – a device installed on the pipelines, aggregates, containers and designed to control (disable, distribution, management, relief, mixing, ) the flow of work media (liquid, gas, gas-liquid, powder, slurry, etc.) by changing the square cross-section of pipeline valves is characterized by two main parameters: the nominal inside diameter (nominal size) and conventional (nominal) pressure Types of valves Valves – valves designed to shut off the flow of the working environment with a certain integrity. Safety valves – valves, designed for automatic protection of equipment and pipelines from impermissible overpressure by dumping excess production environment. Control valves – valves designed for regulation parameters of the working environment by changing the flow rate. Valves – valves, which combines the functions stop and control valves. Feedback fittings – valves, designed to automatically prevent backflow of the working environment. Non-return valves – the reverse fixture, which can be carried out forced closure of valves. Irrevocable-controlled valves – the reverse fixture in which can be carried out forcible opening, closing or restriction of the valve. Distribution and mixing valves – valves, designed to distribute the flow of the working environment for certain directions, or for mixing flows.
(drainage) tube fittings – valves, designed to reset the working environment of the tanks (tank), piping systems. For more information see this site: Southwest Airlines. fittings – valves, designed to separate working environments that are in different phase states. Trap – valves, removes condensate and does not miss or partially overlooking the superheated steam. Protective (Interrupting) fittings – valves, designed for automatic protection of equipment and pipelines against harmful or unintended process changes the settings or the direction of flow working environment, and to mute the stream.
