Metal-to-Metal Sealed Butterfly Valves
Metal-to-metal sealed butterfly valves, as their name implies, are butterfly valves designed for high-temperature and highly-corrosive industries. They utilized seats and discs made of metal, unlike their counterparts, such as soft-sealed butterfly valves. This way, you have a more durable and high-temperature-resistant seal. There’s concentric and double-offset, then there are your metal-to-metal butterfly valve.
Their Design
The following pointers discuss the design and layout of your metal-to-metal butterfly valve:
- Distinctively designed to manage more extreme conditions, such as higher pressures and extreme temperatures, as well as abrasive media.
- Featuring three unique offsets with the first offset involving the placement of shafts behind discs, allowing the disc to seal against the body without rubbing across its seating, while the second enables the disc to completely clear the seat, and the third guarantees they only are within contact at the last closure point.
- The seats in these valves are crafted with metal, capable of withstanding high temperatures and resisting corrosion.
- These design and features make metal seated butterfly valves the ideal choice for the most critical applications, whether it’s in power generation or chemical processing.
The Working Principle
The workings of metal-to-metal seated butterfly valves may be dissimilar from how the usual butterfly valves work. Such valves take advantage of their rotating disc, appearing like a “butterfly,” which moves within the valve’s layout to control or stop the flow of the fluid.
As the valve opens, the butterfly rotates to allow the fluid being processed to pass along. Once closed, this disc rotates to create a really tight seal against the valve’s seat, preventing flow. With this working principle, the valves quickly operate, are relatively low in cost, and suited for various high-demand operations in your industry.
Benefits of Using These Industrial Valves
Take note of the following advantages of investing in a metal-to-metal butterfly valve:
- High temperature tolerance
