Concentric butterfly valve

concentric butterfly valve has various benefits that you may not be aware of among the many different valve types. Small face-to-face dimensions and low torque are a couple of these. Additionally, it is made to function with a wide range of liquids, including semi-liquids and both corrosive and non-corrosive liquids.

High pressure drops across the disc

A butterfly valve is a fantastic choice if you need to replace a sludge pump or control flow in a high pressure facility. They are lighter, simpler in design, and contain fewer moving components than other varieties of valves.

There are numerous types and designs of butterfly valves. Traditional, concentric, eccentric, and high performance varieties are among them. However, there are a few things you should know before making a purchase.

Concentric flanged butterfly valve are the most fundamental variety. The seat in this configuration is a sleeve that is a part of the valve body. Rubber or metal can be used to make the seat.

Low torque

Asymmetrical discs are used in the design of AV-C Series Concentric Butterfly Valves to guarantee good flow characteristics and low operating torque. At full rating pressure, they are capable of bubble tight shutoff. These valves come in sizes as large as 3,000 mm. They are appropriate for demanding applications involving corrosive, chemical, and water environments.

Disc construction can vary based on application. Stainless steel or a liner material like PTFE or PFA can be used to make it. A polymer-lined material may also be used to make some plumbing air release valve. Products with polymer linings may have longer media lives.

A tough sealing ring that encircles the disc makes sure it is tightly sealed when it is in the closed position. A retaining ring on the disc's edge supports this ring.

Suitable for intercepting and adjusting the general corrosive, non-corrosive, and semiliquid

A water distribution system's corrosion may be affected by a number of factors. These consist of temperature, pH, alkalinity, and dissolved solids. These elements may be impacted by water treatment chemicals, which raises the possibility of protective film formation on pipes.

Corrosion can be accelerated by dissolved solids, while it can be slowed down by dissolved oxygen. In the process of treating water, aluminum sulfate is frequently used as a coagulant. Individual customers occasionally use sodium silicate.

An inhibitor of corrosion is calcium carbonate. Water air valve for water supply can have it added to it until it is saturated, but this does not always stop corrosion. The alkalinity and hardness of the water affect how much calcium is present in the solution.
