Valvesonly is the top Double Flanged Butterfly Valve Manufacturer in USA. A double flanged butterfly valve is a type of valve that regulates the flow of fluid through a pipeline using a disc-shaped element that is mounted on a rotating shaft. The valve has two flanges on either end that allow it to be bolted between two pipes in a piping system. The disc is positioned perpendicular to the flow of fluid when the valve is closed, blocking the flow, and rotates on its axis to allow the fluid to pass through when the valve is open. The valve is operated using a handle, gear, or actuator that rotates the shaft to adjust the position of the disc.
Double Flanged Butterfly Valve Manufacturer in USA are commonly used in industries such as water treatment, HVAC, chemical processing, and power generation. They offer advantages such as low cost, low torque requirement, low head loss, and easy installation and maintenance.

Parts
•Body: main casing of the valve
•Disc: circular component that rotates to regulate flow
•Shaft: connects the disc to the actuator or handle
•Seat: the sealing surface where the disc comes into contact with the body
•Flanges: the end connections that allow the valve to be bolted between two pipes.
Types
•Wafer type: designed to fit between flanges and has no flanges of its own
•Lug type: has threaded inserts on either side of the valve body, allowing it to be installed without using flanges
•Double offset: has a slightly tilted disc and shaft for a tighter seal
•Triple offset: has a cone-shaped disc and is designed for high-pressure applications where tight shut-off is required
•Rubber-lined: has a rubber lining on the disc and seat for improved sealing and corrosion resistance
•High-performance: designed for high-pressure and high-temperature applications with superior sealing capabilities.
