Double Offset Butterfly Valve Manufacturers in USA Accord

Valvesonly are trusted Double Offset Butterfly Valve Manufacturers in USA.

What are Double Offset Butterfly Valve?

A double offset butterfly valve uses a disc that is attached to a central shaft to control fluid flow in a pipe. By providing an adjustable opening, this disc regulates the level of fluid flowing through the valve. These valves contain two discs that can withstand pressures and high temperatures of up to 1480 psi. It is controlled manually by a handle, gears, and actuators. These mechanisms spin the valve disc to the proper position for effective sealing or complete valve opening. It can be found at higher pressures than at zero offset. This valve's movement maintains an elongated shape in sealing the valve. They can withstand high pressures and temperatures and can handle gas, oil, steam, and water in a lightweight and cost-effective design.

What are the difference between Double Offset and Triple Offset Butterfly Valves?

The main difference between double offset and triple offset valves lies in their design and sealing mechanism:

Double Offset Valves:

Double offset valves have two offsets: one in the shaft and one in the disc.

The sealing surface of the disc is eccentrically positioned in relation to the valve seat, which reduces friction and wear during operation.

These valves provide a tight shut-off and are suitable for a wide range of applications, including high-pressure and high-temperature environments.

Triple Offset Valves:

Triple offset valves get their name because they have three offsets, which are located in the shaft, disc, and sealing mechanism.

The third offset is the asymmetrical conical shape of the sealing surface. This offset allows the sealing surface to completely disengage from the valve seat during operation, reducing wear and providing a bubble-tight shut-off.

Triple offset valves provide excellent sealing performance, particularly in applications with high pressure, high temperature, and critical requirements where preventing leaks is essential.

They are often used in demanding applications such as oil and gas processing, petrochemical refineries, and power generation plants.
