Lined Control Valves, Lined Plug Valves, and Lined Butterfly: A Comprehensive Overview

 

Lined Control Valves, Lined Plug Valves, and Lined Butterfly: A Comprehensive Overview

An efficient flow control system is not just important but a non-negotiable in several industries that need to operate with:

·        Aggressive chemicals

·        Corrosive substances

·        Extreme working conditions

Among the many valves popular in the market, only some are known to offer durability, versatility and precision. These include:

·        Lined control valves

·        Lined plug valves

·        Lined butterfly valves

Read on to learn about the distinctive features, applications, and advantages of these critical components in industrial systems. We’ll also understand what exactly makes them different from each other.

Lined Control Valves

Lined control valves are typically used to regulate fluid flow, pressure, or temperature in pipelines. There are various kinds of lined valves.

PFA (Perfluoroalkoxy) lined valves can maintain high levels of purity and work in extreme temperatures. The PFA lining gives these valves a non-stick surface. It helps minimise contamination. As a result, PFA-lined valves are popular in industries such as pharmaceutical and semiconductors. The rubber-lined valves are made of materials such as Neoprene and EPDM. These materials give them flexibility and protect the valve from abrasion and corrosion.

The Polytetrafluoroethylene (PTFE) lined valves offer unmatched chemical resistance. This property makes them ideal for applications involving strong acids, bases, and corrosive solvents.

Most lined control valves offer corrosion resistance as the lining material protects the valve from aggressive chemicals and fluids. The valves are designed to allow precise control of fluids. This gives the operators a high level of control. The temperature and pressure tolerance of the lined control valves are high as well.

Lined control valves are popular in industries such as:

·        Chemical

·        Pharmaceutical

·        Food and beverage

·        Water treatment

Lined Plug Valves

Lined plug valves are quarter-turn valves. They have a cylindrical or conical "plug" that rotates within the valve body to control fluid flow. These valves are used for close and open applications. These valves are lined with a material like Teflon or PFA to prevent corrosion from chemical fluids. These are non-lubricated valves, the lining of which separates the valve body from the media. These leakproof valves have a low-pressure drop as the fluid passage is 100%. Some lined plug valves have a three-way valve that allows the operator to divert the flow in two outlets. Lined plug valves are known for their tight sealing, which protects from leakage and offers low maintenance. Their compact design makes them ideal for applications with limited space. So, lined valves can be maintenance-free for several years. These valves are popular in many industries, including:

·        Acid and alkaline handling

·        Petrochemical

·        Pulp and paper production

·        Mining

Lined butterfly valves

Lined butterfly valves feature a disc or plate that rotates and is mounted inside the body. When the disc rotates, the valve opens or closes. This allows the fluid to flow at the desired rate. Lined butterfly valves are known for the simplicity of their design and cost-effectiveness. These valves have been reliable and are especially suitable for industries that require efficient flow of control. The interior surfaces of the valve are lined with corrosion-resistant materials. This makes them ideal for aggressive media. The lightweight build of these valves makes them easier to install and operate on a daily basis. Lined butterfly valves are popular across industries such as:

·        Chemical handling

·        HVAC systems

·        Desalination

·        Wastewater

In a nutshell, all lined valves are great for applications that work with corrosive and abrasive materials, as the lining protects the valves. These valves offer enhanced safety not just by handling challenging fluids but also via their leakproof design.
