Triple offset butterfly valves utilize a patented design that eliminates the issues that plague other types of valves. This valve has a unique sealing mechanism that utilizes line pressure to ensure an effective and bubble-tight seal. This allows it to function in a wider range of applications and is more tolerable of dirt, which minimizes maintenance costs.Source :shiphamvalves.com
This type of valve is a great choice for industrial processes that require bubble-tight shut off without sacrificing performance. It also works well in systems requiring metal-to-metal sealing and is compatible with harsh media. It is often used in steam services, process control and shipbuilding.
Choosing the Right Material for Your Triple Offset Butterfly Valve
In normal operation, the stem of the valve connects to the actuator which allows the user to open or close the valve by rotating it in either direction. When the handle is rotated to the open position, the disc moves away from its seated position to allow fluid or gas to pass through. This allows for a high degree of flow control and can restrict pressure and throttling. When the handle is rotated to the closed position, the disc becomes perpendicular to the flow and seals with a metal seat or a non-metal seat. The combination of the optimized seat angle and Stellite enables this valve to achieve a long service life with little wear or degradation.
Another feature that distinguishes this valve from others is the absence of cavities between the sealing components, which is important for a smooth operation and longer life. This allows the valve to work with a wide range of media and is capable of withstanding corrosive fluids, abrasions and other environmental conditions that can reduce the lifespan of traditional butterfly valves.
