Specialityvalve is a well reputed Double flanged butterfly valve manufacturer in India. The two flanged body pattern allows for easy installation in pipelines and can also be utilised as an end-of-line valve. Due to little disc protrusion beyond the body laying length, this valve is unique in that it can be used in lined pipes. The flow of gas or liquid via a pipe is controlled by a butterfly valve actuator, which turns a disc on a diametrical axis or two semi-circular plates hinged on a shared spindle, allowing only one direction of flow. The rotating stem movement on these tiny actuated butterfly valves is 90 degrees or less. When a butterfly valve is closed, unlike a ball valve, there are no pockets where fluids can become trapped.
Advantages of double flanged valves:
- A double-flanged butterfly valve is easier to mount and centre than a lug or wafer design, and it is also mechanically stronger, making it suited for heavy-duty, large flow-handling circumstances.
- Because it is fastened to the mating flanges of other pipes, Specialityvalve’s Flanged-end valves are easy to install and remove from pipelines. We will guide you through the proper installation of double-flanged valves to avoid misalignment, which can lead to long-term piping system difficulties.
