PLUG VALVES AND ITS APPLICATIONS


The Plug Valve is a control device designed to regulate the flow of a gas or liquid within a high-pressure structure

also for controlling the flow via moderate throttling, these valves are used in on/off position else to divert flow or combine flow.

Plug valves are the vital part of a hydraulic system which works to keep the entire system function efficiently. Valve Manufacturers usually prefer cylindrical or conical design. Present inside the valve is one or more hollow chambers that basically allow flow through the valve when opened since they are most commonly a double port system with an open position that allows for the flow, and a closed position to stop the flow. FEVISA Plug Valves are manufactured as per the industry standards and all Valves are UL FM Approved Valves, that are of perfect design and functionality.

Types :

Designs

  • Short Pattern
  • Regular Pattern
  • Venturi Pattern

A double port valve features two ports allowing fluid to enter or leave, it has two positions, open to allow flow and closed to stop the flow. A double port valve has one path, for flow to pass through it. These ports are usually at the parallel ends of the valve body; hence, the plugs are rotated to a 1/4th of a full turn in order to change from the open to the closed positions.

This type of valve is used to divert the flow or combine the flow. In a 3 way plug valve, the flow from one port can be directed to either the 2nd or 3rd port. Also, it can be designed in such way to connect all the 3 ports together, or shift flow alternatively between the ports.

Based on their benefits:

Lubricated Plug Valve

The Lubricated valves utilizes the kind of lubricant which is made up of a base oil and amorphous or fumed silica. This is in turn injected under pressure between the plug face and body seat to reduce friction and then seal the ports.

Non-Lubricated Plug Valve

The Non-lubricated plug valves are deployed in situations which requires minimum maintenance needs, where liquids are suspected to be trapped inside thus potentially jamming the valves.

Eccentric Plug Valve

These plug valves are the ones which are used for numerous flow control and isolation applications that basically includes clean & dirty water, sewage, sludge & slurries etc.

Expanding Plug Valve

These complex types of plug valves uses multiple components that allow the valve to mechanically expand and give a double block to bleed the function in one valve.

Applications 

Plug valves are highly effective as tight shut-off & on valves, which is better suited for the use with the hazardous liquids & gas corrosive in nature. Valve Suppliers and Valve Manufacturers ensure that that the plug valves are used in the following applications:

  • Oil piping systems
  • High-pressure & Extreme temperature flow systems
  • Chemical servicing
  • Corrosive substances processing

The common industrial uses for Plug Valves are as follows:

Since the Plug valves don’t get clogged, they can handle high-pressure systems. They can also handle the corrosive & dangerous materials, which requires special maintenance and replacement.

High-Pressure Flow Lines

These plug valves can handle high pressure hence they are used in high-pressure applications like coiled tubing, cementing, acidizing, high-pressure/temperature materials, etc.

Upstream Applications

The lubricated plug valves are used here since they won’t get clogged and can handle corrosive materials. They require proper maintenance in short intervals because of these conditions.

Flow Control/Isolation

The plug valves offer a great flow control/isolation of the materials because these valves can easily seal off and separate the liquids in order to avoid the contamination or mixing, which is a crucial method specific high-pressure application.

Oil & Coal Slurries

Plug valves don’t get clogged easily, so that they can handle the abrasive types of materials they are also great at control & isolation, which makes them useful for working on Oil & Coal Slurries.

Conclusion:

A properly designed and planned plug valve is essential for the highly demanding working environment of the various industries that use valves as the control and other functioning mechanism.

One stop solution for all the specifications of customers is Plug Valves which the industry specific standards which in turn is wholly manufactured and supplied by us at Fevisa. We are known a Valve Stockist in USA, Water Valve Suppliers, Global Valve Suppliers etc. Our team of experts ensure that the essential mechanisms are of superior standards in order to work under the required extreme condition

A Comprehensive Guide of Valve Choices in Water Treatment:

Image
  The selection of valves in water treatment systems is critical to ensuring the smooth flow, regulation, and safety of water processes.   With the wide variety of valve types available today, understanding the options and making informed choices can greatly enhance the efficiency and reliability of any water treatment system. In this guide, we’ll explore some of the most commonly used valves in water treatment, the roles they play, and where to find reliable   valve stockist   options across the globe. Understanding Water Valves and Their Roles: Water treatment plants rely on several types of valves to regulate the flow, pressure, and isolation of fluids. Each valve serves a distinct purpose and operates differently based on the system’s needs. Gate Valves:   Gate valves are often used when there is a need for minimal flow restriction or for full isolation. A  gate valves supplier  typically offers these valves for systems requiring fully open or closed positions, ensuring that the sy

Factors to Consider in 2024 While Selecting Industrial Valves for Your Application

Image
In the domain of industrial functioning, choosing valves which are perfect for your application is as important. Indeed, the valves are responsible for regulating flow, pressure or redirecting movement of fluids and gases. Industrial valves are a key factor in maintaining smooth operations. Heading into 2024, the valve technology landscape is in constant flow with many choices, which make it a difficult task for the business to do and there are lots of aspects to take into account to make the best choices. We will begin our discussion with the vital points that must be taken into account when choosing industrial valves in 2024. Application Specificity : First of all, be careful about your application’s specific features. Different industrial processes also need different types of valves. For example, when exact control of the valve is required, globe valves may be appropriate. On the other hand, gate valves are generally used in processes requiring a 100% flow or a complete shut-off.
