Industrial Valves are the electro-mechanical devices which are used for controlling and regulating the flow of Air, Liquid, Slurries, and Gases within the system. Valves are built to handle high pressure, either from fluid or gas and are manufactured using carbon steel, cast iron, stainless steel, and other high functioning metal alloys. Valves are extensively used in Chemical, Oil & Gas, Pharmaceutical, Food Processing, Automobile industry, manufacturing sectors, and even for residential uses.
There are different types of valves which are going to explain as follows.
Gate Valves
A gate valve is also known as sluice valve which is used to that opens by lifting a barrier (gate) out of the path of the fluid. It is a multiturn valve means that operation of the valve is processed by means of a threaded stem. It is the most common valve used for water supply systems. It is a linear motion valve used to start or stop fluid flow.
Different types of Gate Valves as follows:
- Types of Disk
- Solid taper wedge
- Flexible wedge
- Split wedge or Parallel disks valve
- Types of Body Bonnet Joint
- Screwed Bonnet
- Bolted-Bonnet
- Welded-Bonnet

- Non-rising Stem type
Applications of Gate Valves:
Gate Valves are used in different industries such as oil and gas industry, manufacturing, automotive, pharmaceuticals, marine, and all fluid services like air, fuel gas, feed water, steam, hydrocarbon, lube oil, etc.
Advantages of Gate Valve
- Gate Valves prorate good shutoff
- These valves are an energy-efficient valve option, so less power is consumed when compared to globe valves.
- Gate valves are commonly used as bi-directional.
- They are appropriate for high pressure and temperature applications.
Disadvantages of Gate Valves
- These valves cannot be used for control the flow of the fluid.
- They are slow in operation as it takes time to closing and opening.
- It creates Noise and Vibration while it is partially opened.

Butterfly Valves
The butterfly valve is also classified as quarter-turn valve. It isolates or regulates the flow of fluid and the closing mechanism is a disk that rotates. Butterfly valves are popular in the industry because of their low costs, fast operation, and light weight. It requires handles, gears, or automatic actuators for the operation.

- Butterfly Valves are quickly operated.
- Low Maintenance costs.
Disadvantages of Butterfly Valve
- Throttling is limited to low differential pressure service.
- Sealing function is poor.
- It cannot be used for high differential pressure.
Applications of Butterfly Valves
There are many uses with butterfly valves.
- Industrial uses for controlling processes.
- Residential uses.
- Clothes washers.
- Taps at home.
