Types of Control Valve
Rotary control valves
Rotary control valves are valves that use a rotating element to control the flow of the fluid. The rotating element can be a ball, a disc, or a plug that fits into a seat or an opening in the valve body. Rotary control valves are typically used for on/off or throttling applications where fast and precise control is needed.
Some examples of rotary control valves are:
Ball valves: Ball valves have a spherical ball with a hole in it that aligns with the flow path when open and blocks it when closed. Ball valves are simple, durable, and easy to operate. They provide excellent sealing and low head loss. They are suitable for high-pressure and high-temperature applications.
Butterfly valves: Butterfly valves have a disc that rotates around a central axis to regulate the flow. Compared to other valves butterfly valves are cost efficient, smaller in size, and require less maintenance.
Plug valves: Plug valves have a cylindrical or conical plug that rotates inside the valve body to control the flow. Plug valves can withstand extreme pressure and temperature conditions and provide tight shutoff. They are suitable for oil piping systems and corrosive media applications.
Linear control valves
Linear control valves are valves that use a linear motion to control the flow of the fluid. The linear motion can be achieved by a stem that moves a plug, a diaphragm, or a piston into or out of a seat or an opening in the valve body. Linear control valves are typically used for throttling or modulating applications where precise and accurate control is required.
Some examples of linear control valves are:
Globe valves: Globe valves have a plug that moves up and down inside a spherical valve body to regulate the flow. Globe valves offer good control performance and can handle high-pressure drops and high-temperature fluids. They are suitable for wastewater plants, power plants, and process industries etc.
Diaphragm valves: Diaphragm valves have a flexible diaphragm that moves up and down to adjust the flow area. Diaphragm valves are ideally suited for corrosive applications where the body and diaphragm materials can be chosen for chemical compatibility. They are also suitable for abrasive applications where the body lining can be designed to withstand abrasion and the diaphragm can be easily replaced.
Benefits of Control Valve
Automatic operation
One of the most important benefits offered by a control valve is that it controls the opening and closing process of a fluid automatically. Thus, the users don’t have to be careful about closing or opening the valves manually, when these types of valves are employed.
Easy installation
Another great advantage of control valves is that they are absolutely easy to install. Many people can effortlessly install these valves on their faucets without having to call for assistance from a plumber or from the manufacturer. Thus, being easy to install, they help in saving the time and effort of the users.
Reduced wastage
Due to the automatic operations of these valves, there is a great reduction in the wastage of resources. No matter whether these are being used in industrial or manufacturing processes, or at homes, they will ensure less wastage of resources, thanks to their efficient working.
No clogging
The control valves are designed in such a way that the flow of fluids through it is not obstructed. Small particles, deposits, dust, etc. Do not clog the flow of the fluid due to the perfect design of these valves.
Applications of Control Valves
