In industrial piping systems, a major role is played by plug valves for effective flow control that also includes minimal leakage. We also see that these valves are very durable, have quarter turn operation and do put up well with many different types of media; they are very much in use in oil and gas, petrochemical, chemical, and water treatment sectors. Speciality Valve has a larger market of Plug Valve suppliers in India,we see that reliable suppliers are putting out advanced designs which include lubricated, non lubricated, sleeve and eccentric plug valves which in turn, meet a wide range of flow requirements.

What Are Plug Valves?

A plug valve is a quarter turn valve which features a cylindrical or conical plug for control of the flow. The plug which has a void passage (port) that when aligned with the pipe allows flow and when rotated 90 degrees flow is stopped.

Key features of plug valves include: Plug valves are known for their:

1. Simple design with fewer moving parts.
2. Quick operation due to quarter-turn mechanism.
3. Available in 2 way and 3 way plug valve designs for direction flow control.
4. In materials such as stainless steel, cast iron, alloy steel and bronze for various fluids.
5. Due to their tight shutoff abilities plug valves are preferred in high pressure and corrosive environments.

Where Plug Valve is Used

Industries use plug valves in applications which require bubble tight sealing and reliable performance. For example:

• Oil and Gas Pipelines: Managing the full spectrum of crude, natural gas and refined products.
• Chemical Processing Plants: Dealing with strong acids and solvents.
• Water Treatment Facilities: Control of pumps and filters.
• Power Plants: Steam and condensation systems.
• Pharmaceutical and Food Industry: Sanitary plug valve designs for clean processing.

They are able to handle slurry, gas, and viscous fluids which makes them very versatile in many industries.

How Plug Valve Works

A simple yet effective design is that of a plug valve.

1. The plug which is generally tapered or cylindrical in shape is located in the valve body.
2. Upon rotation of the plug by 90 degrees the hollow passage in the plug lines up with the pipeline which in turn allows for fluid to pass.
3. A turn in the other direction does the same thing which is to line up the solid plug with the pipe thus blocking flow.

Lubricating in nature some valve types use a film of oil for decreased friction, in other plug valves which do not have this feature they instead use sleeve or liner inserts for that sealed airtight fit. This also means they do well in high pressure and low maintenance settings.

Plug Valve with Actuator

In the case of large scale or automated operations a plug valve with actuator is a better choice. Instead of manual handwheel operation the actuator which enables:

• Electric Actuation: In automated factories which require precision.
• Pneumatic Actuation: For quick open close operation in pipelines.
• Hydraulic Actuation: For large scale high pressure systems.

Actuuated plug valves which are very much present in refineries, petrochemical plants and offshore platforms that require high degrees of automation and safety.

Plug Valve and Gate Valve Difference

While we see both plug valves and gate valves in use for flow isolation they differ greatly in design and performance:

Plug valves do indeed have the feature of quick isolation and also do very well with aggressive media, on the other hand gate valves are the more common type in large scale water supply systems.

Types of Plug Valves

In India a professional plug valve supplier usually provides a wide range of:

Grease operated Plug Valve For high pressure applications.

1. Non- Lubricated Plug Valve - we have lined them with sleeves or elastomers which in turn makes them a great option for low maintenance use.
2. Sleeve type Plug Valve which is known for its bubble tight seal, very much so in chemical industries.
3. Eccentric Release Valve for slurry and wastewater.
4. 3 Way Valve for Flow Direction This is used in many process industries.

Industries Using Plug Valves

Plug valves are very reliable in areas such as:

1. Crude oil, natural gas, and petroleum products’ transport in the Oil and Gas Industry.
2. Refineries and Petrochemical plants which work with corrosive fluids and hydrocarbons.
3. Generation of Power Control of high pressure steam and condensate.
4. Pharmaceutical Production Issues of clean flow.
5. Food and Beverage Industry Sanitary designs for dairy, beverages, and edible oils.

Advantages of Plug Valves

• Quick Turn Operation we save you time and energy.
• Superior Closure Also performs when pressurized.
• Durable in design for use with aggressive and thick fluids.
• Wide variety of materials stainless steel, alloy steel, cast iron, bronze.
• Low care Non-lubricated types which require less maintenance.
• Compact design which is best for tight spaces as compared to gate valves.

Why Choose Speciality Valve as Your Plug Valve Supplier in India?

• Wide range of lubricated and non-lubricated, sleeved, eccentric, and 3 way plug valves.
• Engineered with high quality materials for corrosive and high pressure applications.
• Available in manual, electric, pneumatic and hydraulic actuation.
• Designed to the API, ANSI, and BS standards.
