Importance of using the valves

1. Importance of using the valves In industries that use automation, there are always input, and output variables, and vibrations cause deviations that affect production stability and quality. The principle of operation of the valve is that there is a pressure difference. From another perspective, it can be considered the opposite of a bomb, but when they are placed, the pressure increases, and the former decreases. The general equations governing the behaviour of incompressible fluids passing through the control valve are: The Industrial Valve is an important factor in the automation of industrial processes in regulation because its function allows the flow rate to be changed. The interior of the control loop is as important as the main elements, transmitters, and controls. The control valve consists of a body and a servo motor. Among them are shutters and seats provided by flanges for connecting to pipes. The obstructer performs the function of controlling the flow of fluid and can act in its own axis or make a rotational movement. It penetrates the body cover and is attached to the stem driven by the servo motor.

2. Flow control of fluid power systems is important because the speed of movement of hydraulically driven machines depends on the state of the pressurized liquid. It can also be operated manually, hydraulically, electrically, or pneumatically. Valve type Several types of the Trunnion ball valve are used in the industry dealing with automated processes, but they depend on the design of the body and the movement of the plugs. Those that move in the direction of your axis are categorized as gloves, angles, three ways, gates, cages, or Y-valves. The glove valve can be a single seat or double seat and a balanced plug. In the first case, a larger actuator is needed to close against the differential pressure of the process. It is used when the fluid force is low and leakage in the closed position must be minimized. A hermetic seal can be achieved as long as the shutter has a Teflon washer. Another type is commonly used to mix fluids or to divert flow between two outlets, which are usually considered three-way valves involved in heat exchanger temperature control. Test improvements It is believed that more than 60% of Double block and bleed valve installed in the industry have performance problems, most of which can be fixed without removing the equipment from the process line. Internal parts Removable metal parts that are in direct contact with the fluid are considered internal parts of the valve. These parts are the stem, packing, packing collar, guide ring, plug, and seat. It should be noted that the latter also has the function of closing the flow of fluid, forming the "heart of the valve" by controlling the flow thanks to the variable passage orifice formed when the relative position changes. Plugs and seats are usually made of stainless steel. This is because the material is resistant to corrosion and fluid erosion. Control and tightness Each control valve must be designed and selected to provide reliable operation and control under the specified design and operating conditions.
