In order to keep the wafer-style butterfly valve in place and align it with two mated flanges, it frequently only contains two or four non-threaded holes. A long bolt or threaded rod that passes directly through the wafer valve's two flanges is used to install it. The valve is secured in position by tightening the flanges together. A wafer butterfly valve's principal function is to keep a seal and prevent double-directional pressure differentials in liquid flow.
The wafer form of butterfly valves was created to maintain a tight seal and safeguard against bi-directional pressure differential in order to prevent any backflow in systems that were designed for unidirectional flow.
This butterfly valve is positioned in the middle of two pipe ends. In terms of flanges with holes, the pipe ends. The valve body is encircled by long bolts to keep it firmly in place. The valve body is completely covered in bolts. Manufacturers of wafer butterfly valves might choose to include or exclude flange holes on the valve body. To improve a leak-proof connection, tightly fitted seals like gaskets and O-rings are utilised between the valves and pipe. Manufacturers of wafer butterfly valves create these valves with manual or automatic operation options. While manual types employ a handwheel or hand lever to start or stop, automatic versions use actuators. These valves are compact because of their short length.

Wafer butterfly valves are used in a variety of industries:
• Oil and gas
• Chemical processing
• Water and wastewater processing and transportation
• Food processing
• Manufacturing
• Shipbuilding and shipyards
• HVAC

Advantages of Wafer butterfly valves :

• It has a built-in simple, economical design with fewer parts, making maintenance easy and repairs convenient.
• Its wafer-shaped, lightweight body makes it affordable in terms of the valve's initial cost as well as installation costs related to man hours and piping requirements.
• It may move muck while leaving only a small amount of fluid at the pipeline outlet.
• They readily open and close and provide effective sealing at low pressure.
• When compared to a ball, its disc is lightweight.
• A butterfly valve requires significantly less structural support than a ball valve with the same diameter does.
• A smaller installation area is required.
• Quick and easy opening and closing
• It is often associated with lesser maintenance since there are fewer moving parts and no pockets to collect fluids. It is great for working with slurries or liquids that have a lot of dispersed particulates.

Disadvantages
• Even with the disc fully expanded, a specific area constantly faces the flow. Therefore, regardless of the setting, a butterfly valve's functioning always results in a pressure switch over the valve.
• It does a terrible job at sealing.
• Butterfly valve throttling is only possible in low-pressure drop systems.
• Flow choking and possible cavitation are concerns when butterfly valves operate.

• Lug Butterfly Valve Manufacturer in USA
Valvesonly is one of the top Lug butterfly valve manufacturer in USA. Butterfly valves in the lug form are designed to work with either electric or pneumatic actuation. Based on the application and the flow media, the disc and seat materials should be chosen. Metals like ductile iron or steel are typically used to make lug-style butterfly valves. On the valve flanges, they have threaded lugs with tapped holes for bolt connections. End-of-line service is suitable for lug-style butterfly valves, however a blind flange is always advised. Butterfly valves with lug versions are similar to 3-piece ball valves in that one end of the line can be removed without affecting the other side. Threaded inserts, flanges, and two sets of lugs (bolts) that don't require nuts because each flange has its own bolts can all be used to accomplish this. It's also crucial to remember that lug butterfly valves can be cleaned, inspected, repaired, or replaced without having to shut down the entire system (you would need to with a wafer butter valve).
The lug type of butterfly valve is built similarly to a three-piece ball valve in that one end of the line can be removed without affecting the other. Although lug butterfly valves can be used for end-of-line operations, a blind flange is typically recommended. Materials for the disc and seat must be provided in line with the application.

At the extremity of a pipe, lug butterfly valves are usually employed because there isn't a second flange to safeguard the lugs. The valve is instead built using lugs with tapped holes that match the bolt design for the flange's size and pressure category. After passing through the flange holes, bolts are placed in the tapped holes of the lugs.
