Offset butterfly valve

Controlling the flow of a liquid through a pipeline, such as water, typically requires the installation of an offset butterfly valve. Either a flanged end type or a double offset type can be used for the valve. The valve is adaptable, thus it can be utilized in a variety of contexts.

Double offset butterfly valve

The double offset butterfly valves, also known as high performance butterfly valves, are most commonly used in the power generation, heating, ventilation, and air conditioning (HVAC), chemical, and water industries. They are built for airtight sealing and are appropriate for a wide variety of different applications due to their design. Because they require little to no upkeep, they are exceptionally long-lasting, and they have a great tolerance for being compressed.

Because of their superior sealing qualities and lengthy lifespan, butterfly valves are frequently used in a variety of applications. They find widespread application in the fields of dry bulk handling, oil and gas drilling, the manufacture of food and beverages, and a great many other spheres. In addition, they find applications in facilities that handle wastewater and water.

The disc, the seat, the stem, and the offset are the four primary components that make up a butterfly valve. These components are constructed using a wide variety of materials, including metals, plastics, and numerous other elastomeric substances. Plastics are used around the seat edge of some butterfly valve types in order to help avoid wear caused by metal on metal contact. Double eccentric butterfly valves almost always have metal seats, which allow for a reliable and friction-free sealing.

The typical materials used to construct the seat are natural rubber, EPDM, and Teflon. Hastelloy and titanium are two of the available metals for seat possibilities. These components are fantastic choices for corrosive environments, such as those found in the oil and gas sectors.

It is the purpose of the disc to produce a smooth opening and closing movement, which in turn reduces the amount of wear and tear that is placed on the valve. Along the outer edge of the valve disc is a substantial knife edge, which serves the purpose of preventing the valve from becoming affixed to the seat.
