What is a wafer butterfly valve?
What is a wafer type butterfly valve installed?
-
Align the Valve: This step involves positioning the butterfly valve right in the center of the flanges, which are spread out on either side of the piping system.
-
Insert Stud Bolts: Once the valve is in the right position, it should be fastened securely using stud bolts, which need to be inserted through the pipeline’s flanges.
-
Fix the Bolts Loosely: It’s recommended to first lightly fasten the bolts, ensuring all of them suitably traverse through the guiding lugs. These lugs play a crucial role in centralizing the valve.
-
Shut the Disc: During the installation, the disc must be maintained in a shut position, preventing potential harm to the sealing surfaces or the disc itself.
-
Finalize the Installation: After confirming proper alignment of all elements, proceed to completely secure all the bolts.
What is the difference between a wafer and a flanged butterfly valve?
The primary distinction between a wafer and a flanged butterfly valve lies in how they connect to the pipelines.
A wafer butterfly valve doesn’t have flanges. Instead, it’s designed to fit snugly between two pipe flanges, creating a secure seal using the pressure from the bolts and nuts. This makes it easy to install or remove and also saves a substantial amount of space compared to other butterfly valves. It’s worth noting that it has a slightly less reliable seal than the flanged type, but is generally cheaper and often used in systems where easy removal isn’t necessary.
On the contrary, a flanged butterfly valve has its own flanges on both ends of its valve body. These flanges are then connected directly to the pipe flanges. As a result, its sealing performance is considered to be more reliable than its wafer counterpart. Moreover, flanged valves are generally easier to align and provide a stronger, more durable connection. However, they are more expensive and take up larger space than wafer types.
In general, the choice between a wafer and a flanged valve depends on the specific requirements of the system they’re being implemented into.
What are the advantages and disadvantagesof a wafer butterfly valve?
- Versatility: They are capable of handling various types of fluids, which makes them suitable for a wide range of applications.
- Easy Operation: They offer convenient opening and closing mechanisms, requiring less effort and can be operated frequently without any issue.
- Low Fluid Resistance: Butterfly valves are known for their low fluid resistance, which is particularly beneficial in controlling the flow of fluid.
- Potential Leakage: Wafer butterfly valves may not provide a completely airtight seal, and this can result in leakage, especially when functioning under high-pressure conditions.
- Restricted Sealing Capability: One significant limitation is their restricted sealing capability, which renders them non-ideal for high-pressure environments.
- Limited Working Pressure and Temperature Range: Wafer butterfly valves may also have a smaller range for working pressure and temperature compared to other types of valves.
Wafer butterfly valves, renowned for their distinctive architecture, compete well within various industries due to their compact design, effective sealing mechanism, and the ability to manage pressure differentials efficiently. These valves offer versatile operational capabilities, easy handling, and low fluid resistance, making them a preferred choice for controlling the fluid flow.
However, it’s critical to consider their potential limitations, including a less reliable seal compared to the flanged types, restricted sealing capability under high-pressure conditions, and a smaller working pressure and temperature range. Although providing superior cost and space efficiency, their suitability depends on the specific requirements of the system they’re implemented in.
