Valves are used to control the flow rate of fluids or gases. They are used in households and industries. There are many types of valves, and different types have different functions. Let’s take a look at the types and applications of valves.
What Is A Valve?
A valve is a mechanical device that is driven by an external or internal force and then regulates the flow rate in the pipeline.
The Purpose Of The Valve
● Allowing fluid to transport or cut off
● Regulating the flow and pressure in the pipeline
● Changing the direction of the fluid in the pipe
● Mixing and diverter
Types Of Valves
According to the actuation types, the valve can be divided into manual valve and automatic valve.At the same time according to the motion type, it could be linear motion valves and quarter turn valves.
Gate Valves
Gate valves and globe valves are both linear motion valves. Gate valve could open or close fully to transport and cut off the flow rate.
Types Of Gate Valves
● Wedge gate valve
● Parallel Disc Gate Valve
● Rising stem gate valve
● Dark stem gate valve
● Knife gate valve
Applications Of Gate Valves
Gate valves are suitable for applications that require transport or shut-off, such as wastewater treatment, agricultural irrigation, shipbuilding, power plants, paper and pulp, etc.
Globe Valves
Globe valve could transport, shut off and regulate the flow rate. Compared with gate valve, globe valve has an excellent flow control function
Types of Globe Valves
● Type Z
● Type Y
● Angle type
Applications of Globe Valves
The globe valve is suitable for use in industries that need flow rate to regulate and is suitable for use in high temperature and high-pressure conditions.
Butterfly Valves
Butterfly valves and ball valves are both quarter-turn valves. Turn the handle or wheel to open or close the valve. Features of butterfly valve including compact design, lightweight, saves installation space, and has a wide range of sizes.
Types Of Butterfly Valves
According to the type of seals, butterfly valves can be divided into soft-seated butterfly valves and hard-seated butterfly valves
According to the design, the butterfly valve can be divided into single eccentric butterfly valve, double eccentric butterfly valve, and triple eccentric butterfly valve
According to the connection method, the butterfly valve can be divided into wafer type, lug type, flange type, tri-clamp type and weld type
Application Of Butterfly Valves
Butterfly valves are suitable for industries with large pipe sizes, such as HVAC, wastewater treatment, seawater desalination, chemical industries, and so on. At the same time, butterfly valves are more suitable for use in low-temperature and low-pressure conditions. If your industries require high temperature or high pressure, the hard seated triple offset butterfly valves are recommended.
Ball Valves
By rotating the handle a quarter-turn rotation, the ball is driven to rotate, thereby opening or closing the valve. Ball valves are also used for on off and regulating.
Type Of Ball Valves
According to the design, ball valves can be divided into trunnion mounted ball valves and floating ball valves
According to the flow direction, the ball valve can be divided into two-way ball valve, three-way ball valve, four-way ball valve or five-way ball valve
According to the connection method, the ball valve can be divided into thread type, flange type, weld type and tri-clamp type
Application Of Ball Valves
Ball valve is the most widely used valve currently, it is suitable for various industries, such as food and beverage, wastewater treatment, oil and gas, chemical industry, shipbuilding industry, and so on.
