Plug Valve Manufacturer in USA

What is a Plug Valve?

Plug valves are classified as quarter-turn,  rotary motion straight-line valves that are normally used in the fully open and fully closed positions.

Plug valves are referred to as quarter-turn valves because the plug rotates 90 degrees between the fully open and fully closed positions. On/off valves either allow flow (on) or obstruct it completely (off). These valves are also known as isolation valves, because they can effectively shut down flow into a segment of a system, often for maintenance to be performed. 

Plug valves, also named Cock Valves obtain their name from the type of valve disc used. Plug valves are made up of a stopper across a passageway. The stopper is a plug with a hole through it. The hole is called the port. The plug can be cylindrical or conical. When the port is in alignment with the passageway the media can go through. When it is moved 90 degrees, the passageway is closed. The handle (actuator) indicates the position of the valve (in-line = open, perpendicular = closed). 

Externally, on the valve’s body, it has 2 housings at both ends to be screwed to the pipes. Inside the valve's body, we can find the shutter, which can be compared to some conical corks that can block the passage of the flow. On the top of the shutter (typically attached to the end with a larger diameter), we can see the stem to which the actuator is connected. 

SVR Global is a dependable plug valve manufacturer in USA that offers a wide range of  Plug Valves. Our Plug Valves are tested to ensure they meet all of our clients’ requirements. We also offer customized Plug Valves that are tailored to specific industrial demands.

Plug valves are not suitable for throttling/regulating flow although there is a diamond port design that is suitable for throttling applications. 

Plug valves are available in lubricated or non-lubricated designs.

SVR plug valve specializes in a variety of plug valves, including 

Flange plug valve

Threaded plug valve

3-way plug valve

Lubricated plug valve

Eccentric plug valve

Lined plug valve

Sleeved plug valve

The most common plug valve model is the 2-port valve with two positions: open to making the fluid flow and closed to stop the flow. To go from open to close position the shutter rotates by 90 °. 

It is also possible for a plug valve to have more than two ports. A multiport plug valve has the great advantage to make the flow split into as many ports as the valve has. 

Eccentric plug valve manufacturer in USA:

SVR Global is the largest Eccentric Plug valve manufacturer in USA. Eccentric Plug valves are specialized valves that are used to handle wastewater flows. When the valve is supplied with glass or rubber linings, it can be used for Abrasive Fluids as well. Because it's a quarter-turn valve, it's simple to automate for process flow or pressure control. These Eccentric Plug valves have a cast iron body with a removable bolted cover. The plug features a tough covering that seals against the body's nickel-welded seat. The Eccentric Plug Valve's valve shaft is usually integrally cast as part of the plug and rotates in stainless-steel bearings in the bottom of the body and the cover.

Eccentric plug valves manage corrosive, coking, and other difficult-to-handle fluids by throttling or turning them on and off. For durable service in slurry situations, the flanged valves have streamlined flow passageways and durable, metal trim components.

Jacketed Plug Valve MANUFACTURER IN USA

SVR Global is a leading Jacketed Plug Valve manufacturer in USA. Jacketed plug valves are easy to open and close, have minimum resistance to flow and are easy to maintain and work well when they are sealed. These valves are used in chemical, petroleum, and other industries. SVR Global manufactures good quality and amazing jacketed Plug Valves. A Jacketed Plug valve is a valve that prevents or starts flow using a plug that controls the flow in the valve. When a rapid operation is necessary for the system, plug valves are used instead of a gate valve. It's frequently used in high-pressure applications and applications that work with high temperatures. Jacketed Plug valves have the ability to keep the system warm and cold at the same time. It can minimize medium heat loss in the pipe and pass medium that solidifies at room temperature.

Lubricated Plug valve manufacturer in USA:

SVR Global is a leading and reputed Lubricated plug valve manufacturer in USA. To start or stop the flow of the medium in a system, a lubricated plug valve with a tapered or cylindrical plug is used. This valve has a lubricated plug inside it which helps in the flow of the medium. The valve’s lubricant minimizes the force that is necessary to open and close, allowing it for smooth plug movement in the valve. They can be used in both high-pressure and high-temperature conditions. It is manufactured by using corrosion-resistant materials to keep the valve from corroding.

To minimize friction and seal ports, the Lubricated Plug Valve uses a lubricant that is made up of base oil and viscosity improver that is injected under pressure between the body seat and plug. While there are four different types of plug valves, the two most commonly used plug valves are lubricated and non-lubricated plug valves. The lubricated plug valves work well in processes that use mediums that carry slightly abrasive particles, such as dirty upstream applications, and gas pipeline systems This type of valve has a lubricated plug that helps to start or stop the flow of the medium in the valve.

Applications of Plug Valves:

Plug valves are often used in the following applications:

Chemical serviceCorrosive substancesVacuum to high-pressureOil piping systemsExtreme temperature flow applicationsHigh-pressure flow applications

Advantages of Plug Valves:

Simple design with minimal partsAllow for in-line maintenance.Low flow resistanceProvide dependable leak-free service.The use of many ports reduces the required valves and allows flow direction changes.Tight shut-off Fast-actingLittle pressure dropFire safety and durability- Because the actual plug and body seating surface are not exposed to the line fluid, there is less chance of corrosion or erosion.Versatile enough to be used with huge flow rates.Plug valves are simple to open and close (except for large dimensions).Easy to assemble and operate.There are fewer rotating components.Require relatively little upkeep.Ensure a tight seal.Has a low initial cost.May be readily removed for maintenance, repair and cleaning.Suitable for multiport applicationsLubricated plug valve seat problems are easily repaired in line with the addition of grease.

Disadvantages of Plug Valves:

Because of the high friction, they require more force to operate.Larger valves require an actuator.Experiences pressure drop due to reduced port pressure.Incompatible with throttling applications.Have the potential to be irritating.The tapered plug design results in a smaller port.Because of the conic plug, the plug valve transitions narrow flows.Expensive.More substantial.More space is required. The plug valve seat is often constructed from plastic or polymer materials, this makes the valve ill-suited to high-temperature applications. 

Industries that use Plug Valves:

Plug valves are used in a variety of industries, including 

Oil and gasChemicalsPower generationProduction Wastewater treatmentFood and beverages
