One of the market’s most useful types of valves is the PVC butterfly valve. They may be applied in several activities, such as industrial operations, HVAC, and water treatment. PVC butterfly valves are a great option for many sectors because of their long lifespan and resistance to corrosion. PVC Butterfly Valve from Petron is a great option for various industrial applications because of its dependability and longevity. Hydroplast is the best option if you need a dependable, long-lasting valve for your application.

How Does It Work?

PVC butterfly valves are made to control the flow of gases and liquids through pipe systems. A disc on a shaft attached to an actuator makes up the valve. The valve may be opened and shut using the actuator. The disc is moved when the actuator is rotated, which also moves the shaft. When the valve is open, a hole in the center of the disc allows liquids or gases to pass through. The actuator closes and stops the flow of fluids or gases when turned the other way.

Types Of A PVC Butterfly Valve

Butterfly valves are essential when a tight shut-off is required. The disc may open and close any program that can rotate 90 degrees slowly. They are preferred to other kinds of valves because they frequently weigh less and cost less money. Zero, double, and triple offset butterfly valves are three main types.

Zero Offset Butterfly Valves

These valves alleviate potential tightening problems between the butterfly valve’s seat and disc. The valve’s stem and disc are in the center, and a seal is made when the disc deforms the soft seat and fully frictions over the whole working cycle. Applications requiring chemicals, coatings, food, specific solids, and abrasives can be handled by this valve. Since the PVC Butterfly Valve seat covers the body, most media traveling through the valve won’t touch it, which is one advantage.

Butterfly Valves With A Double Offset

The stem center is offset from the disc and valve centers in the double-offset configuration. The construction considerably reduces unnecessary over-compression and scraping between them by allowing the valve disc to depart the valve seat quickly. This design also helps slow the wearing process and increase the valve’s useful life. This broadens the range of high-temperature applications for butterfly valves by enabling the use of metal for the valve seats, which eliminates the need for scraping.

Three Offsets Butterfly Valves

The triple offset design extends cycle life and decreases seat and seal wear by reducing friction between the seat and seal ring through the flow channel. When gate valves are required, such as when a metal seat, tight shutdown, and/or quarter-turn actuation are needed, triple offset butterfly valves are employed instead. But even when there is an emergency shutdown, triple-offset PVC Butterfly Valve can function more often and swiftly than gate valves. This valve, which has low torque, is suggested for use in both high- and low-temperature applications.

Lug Style Butterfly Valves

They behave very similarly to a real union ball valve. They enable the removal of either of the nearby pipe segments while the system is still in use. These valves do this by fastening to each of the surrounding flanges with a separate pair of two bolts. A solid seal is maintained between the valve and one section of pipe by the final set of bolts. Lug butterfly valves are ideal for situations where routine maintenance tasks like cleaning are required.

Wafer-Style Butterfly Valves

There aren’t as many bolt mounts, making lug BF valves less noticeable. Typically, they only contain two or four holes, which are used to anchor and align the valve with the pipeline. They are often twice as pressure-rated as equivalent lug-style valves because of how firmly they sit in place. The fundamental drawback of wafer butterfly valves is that, unlike lug valves, they do not allow for simple maintenance. A system shutdown is necessary before doing any repair on or near a wafer-style PVC Butterfly Valve.

How to Operate Different Types of Butterfly Valves?

Butterfly valves can be distinguished from one another by their modes of operation. Handles and gear wheels are the two manual techniques. Depending on the model, automated actuation may also be an option! Lever-operated butterfly valves open and close the valve by turning the stem with a quarter-turn lever, which frequently has a locking mechanism. The BF valve operates this way because it is the simplest but most difficult and impractical for larger valves.

Another frequent way to open and close butterfly valves is with a gear wheel! A hand-operated wheel turns a gear connected to the stem to move the disc. For both large and small butterfly valves, this technique is employed. Gear wheels facilitate butterfly valve operation by replacing the need for human strength with a mechanically intuitive method for turning the disc.

Actuation is the last way to operate a butterfly valve, which is normally only used in high-demand industrial applications. With big butterfly valves, automatic opening and shutting are required. Only actuators that adhere to certain mounting requirements will fit on custom-made valves. We won’t try to address those criteria here because that is the topic of another blog article.

Over other types of valves, PVC Butterfly Valve provides a variety of benefits. They require very little upkeep and are simple to use. Compared to other valves, they are also less prone to leak. PVC butterfly valves come in various sizes and can be specially made to meet your requirements.
