Valves are known as those devices that can control the flow of fluids either they are in liquid or gaseous form. Basically, valves can be used for many different purposes varied from medical disposables to giant oil plants and these purposes sized valves from smaller to the giant one. If we could talk about working phenomena of the valves so simply it can be defined as: it is quite similar with the valves in human bodies that regulate the flow of blood through heart pumping to other parts of body. Beyond that, there are so many types of valves you may found varied according to their functionalities whereas some of the common types of valves are defined below for your assistance.
Ball Valves
Ball valves are most commonly used valves that can be seen in many residential and commercial purposes. Basically, ball valves are consisted of a body which contains a ball with hole at the center to regulate the flow of fluids like gas and water; a horizontal lever is use to directing the valve where to move and a stem at the top holding both lever and ball.
Check Valves
Check valves is considered as second most common type of valve that can be seen in most of the routine applications. Check valves are usually simple valves used to control the flow of fluids from one side and these valves are also consisted of two-ports body, one for the entrance of fluid while other for the exit.
Gate Valves
Gate valve is generally made up of metals like stainless steel and it is one of the oldest valve types that regulate the fluids according to your demands. Gate valves consist of door vertically attached to the stem, when lever rotates the door blocks and releases the pass-away.
Hydraulic Valves
Hydraulic valves are very heavy duty valves used to control the fluids either they are highly pressurized or required different flowing directions. Hydraulic valves varied into some sub types according to uses like pressure control, flow control and direction control valves.
Needle Valves
Needle valves are one of the comprehensive types of valve used to control high pressure fluids. Needle valves consist of a needle style plunger installed vertically or horizontally with the stem and used to regulate the speed of fluids.
Valve Parts
Valves majorly consist of 7 parts that are following:
Body - Body contains whole of the elements of valves.
Bonnet – Bonnet covers the whole upper element of valve.
Stem - Stem is operational part that connects the actuator or lever to disk or ball.
Actuator - Actuator or lever is a handle for moving ball and stem.
Packing - Packing is the seal that controls the overflow of fluids from valve.
Seat – Seat is attachment commonly stick with disk.
Disk - Disks are the plates and sometimes balls that control the flow of fluids.
All of the above information, these valves look similar to each other but functionalities will be justified when you feel the need conversions of fluids in different ways. Valves are one of the fittings that will keep your fluids safe from many unsecure situations, so they are the necessary parts of industry.
