    4 Reasons Not To Use Butterfly Valve When Handling Dry Material

    Butterfly valves are not designed to handle dry bulk solids. They were designed for gas and liquid applications. The abrasiveness of dry bulk solids erodes away on butterfly valves to the point where they no longer properly seal and need to be replaced.

  • What are the main differences between wafer vs lug butterfly valve?

    What are the main differences between wafer vs lug butterfly valve?

    Wafer and lug butterfly valves are two types of Butterfly Valve designs used in HVAC systems. The main difference between the two types is that wafer valves have a compact design with sealants placed at the edges, while lug butterfly valves are more complex, with bolts and nuts keeping the parts together. Other key differences include size, strength, diameter requirements for installation and maintenance processes involved. Both have their own advantages when used in HVAC systems, making it important to understand each type before deciding on which type to install.

    Wafer Type Butterfly Valve and Lug Type Butterfly Valve

    Wafer type butterfly valve is the most economical version and it is sandwiched between two pipe flanges and the flange bolts surround the valve body. The pipe flanges are connected through long bolts that cross the entire valve body. The sealing between the valve and pipe flanges is accomplished by using a tightly fitted seal, such as an O-ring, gasket, precision machined, along with a flat valve face on the downstream and upstream sections of the valve. This type of connection is designed for sealing against bi-directional differential pressures and to prevent backward flow in systems designed for universal flow.

  • Wafer Style, Lug Style Butterfly Valves

    Wafer Style, Lug Style Butterfly Valves

    A wafer style butterfly valve is a quarter-turn valve designed to mount between pipe flanges and features a disc mounted on the stem of the valve inside a rubber seat. When the disc and stem are turned 90o, the flow of fluids in a pipe starts or stops depending on the position of the disc. In the closed position, the disc sits inside the seat of the valve to form a tight, secure seal that prevents leakage. When the valve is opened, the disc is parallel with the flow of the fluid and allows it to pass. In the closed position, the disc is perpendicular to the pipe.
