Most Commonly Used Industrial Valves in Pakistan

If you are new in Industrial Valves and you want to get the basic knowledge of valves used in different industries of Pakistan. Then this article would be the ideal source of information for you. Firstly we will explain you what is a valve and then we will discus about different valves types commonly used in Pakistan.

What are Valves?

Simply, industrial valves are the products that regulate the flow of liquid or steam for different industries like gas, water industries or chemical industries etc. Most common types of industrial valves used in Pakistan suitable for different industrial tasks include – ball valves, gate valves, check valves, globe valves, butterfly valves and y-strainer valves etc. Each valve has its own advantages and applications for different industries. For example, ball valves are mostly used for construction projects while butterfly valves are common for automobile industry. Let us discuss about industrial valves in brief one by one here.

1. Ball Valve

Ball valves are most commonly used valve in Pakistan with excellent option for smooth passageway that regulates flow of liquid. These valves are two way valves to regulate the fluid in both directions (clockwise or anticlockwise). In ball valves we can have two way, three way as well as four way option also available.

Body Material:

Ball valves come in different body materials like Brass, Cast Iron, Carbon Steel, Stainless Steel etc. Most commonly used body material in Pakistan is Brass Body Ball Valves.

End Connection:

Ball Valves come in different end connections like Threaded, Flange Type, Socket Weld, Butt Weld. Mostly commonly used end connection type in Pakistan is thread type.

Ball Valve Operation Type:

Ball Valves are operated differently like you can find valves that operate with manual handle (In Pakistan people also called these ball valves as Handle Valves, A commonly used term in our local industry). Ball Valves can also be operate with the help of a gear, motor or actuator. 

2. Gate Valve

If you require a minimum flow in your application then gate valves are optimum. In this case, controlling fluid is very easy. For gate valves, there is one gate that stops flow of liquid by moving down ward and open the flow by moving upward. These valves have flanged ends that should be dimensionally perfect and compatible for different applications.

Body Material:

In Pakistani market Gate valves comes in body materials like Brass, Cast Iron, Carbon Steel (WCB), Stainless Steel etc. For fire fighting and building construction projects mostly brass body gate valves are used in Pakistan. For industrial low pressure upto PN16, Cast Iron Body is used in Gate Valves. As well as pressure and temperature is increased gate valve body material moves from Carbon Steel to Forged Steel and Stainless Steel with high pressure class. 

End Connection:

Like Ball Valves, Gate Valves comes in end connections like Threaded, Flange Type, Socket Weld, Butt Weld. Mostly commonly used end connection type in Pakistan is thread type and Flange Type Gate Valves.

Gate Valve Operation Type:

Gate Valves can be operated with a wheel held at the top of the valve. In other options there are Gear Operated gate valves as well. 

In high pressure Gate Valves, You can check out our 1500 Class Gate Valve of size: 4" (DN100) here.

3. Check Valve

Check valves has different names in the market. It is also known as Non Return Valve (NRV), Reflux Valve, Retention valve, one-way valve and Clack valve. Check valve is valve that normally allows fluid (liquid or gas) to flow through it in only in one direction.

Body Material:

Mostly in small sizes for water applications brass body check valves are used in Pakistan. For low pressure industrial use Cast iron check valves are used. For high pressure and temperature carbon steel and stainless steel body material is used.

End Connection:

Small sizes comes in threaded end connection in check valves while for larger sizes end connection comes in flanged end. Forged steel body material check valves also comes in Socket Weld and Butt Weld end connections.

Check Valve Operation Type:

Check valves are self operation valves. With the pressure of the fluid it let the fluid to go on but when pressure reduce it will not let the fluid to go backward.

4. Globe Valve

globe valve, different from ball valve, is a type of valve that used for regulating flow in pipeline. It consist of a movable plug or disc element and a stationary ring seat in a generally spherical body (that is why it is called Globe Valve).

Body Material:

Cast iron, brass, carbon steel, gun metal and stainless steel are the most common materials for globe valves. In Pakistan globe valve is also locally manufactured in Cast iron material.

End Connection:

Globe valves comes in different end connections like Threaded, Flange Type, Socket Weld, Butt Weld.

Globe Valve Operation Type:

Globe Valves can be operate with a wheel, motorized operation, Gear operated.

5. Butterfly Valve

Just like Ball valve, butterfly valve is also a 90 degree operating valve. A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism in butterfly valves is a disk that rotates inside valve.

Body Material:

Cast iron, WCB, and stainless steel are the most common body materials for butterfly valves. Disk material of the butterfly valves comes in Stainless Steel, Brass and Cast iron. Most commonly used disk material used in Pakistan is Stainless Steel (SS304).

End Connection:

Butterfly valves are compact and smart as compare to Gate and Globe Valves. The butterfly valve is installed between two flanges using nuts and bolts. Butterfly valves also comes with flange end connection but there is not a big demand of such butterfly valves in Pakistan.

Butterfly Valve Operation Type:

Butterfly valves can be operate with a lever, motor, actuator and Gear.

6. Y-Strainer Valve

Y-Strainers are industrial valves for mechanically removing unwanted solids from liquid, gas or steam lines by means of a perforated or wire mesh straining element. These strainers are used in pipelines to protect motors, pumps, control valves, steam traps, regulators and other process equipment.

Body Material:

Y-strainers comes in brass, cast iron, wcb and stainless steel material. Mesh of the y-strainer comes in stainless steel material.

End Connection:

Small sizes are preferred in threaded end connection while larger sizes comes in Flange End.

Strainer Valve Operation Type:

There is no need of operation for strainers. As they are just used to remove unwanted solids from the line. Mesh can be wash or replaceable if required with the passage of time.
