Wafer Type Butterfly Valve Description
A wafer type butterfly valve is a type of valve that uses a disc-shaped butterfly plate to control the flow of fluids. The valve is called “wafer type” because it is installed between two flanges without the need for additional hardware. It is often used in applications where space is limited or weight restrictions apply.
The butterfly plate in a wafer type butterfly valve is positioned in the center of the pipe and rotates on a spindle. When the valve is in the closed position, the plate is perpendicular to the flow, blocking off the flow completely. When the valve is open, the plate is parallel to the flow, allowing fluid to pass through unrestricted.
One advantage of a wafer type butterfly valve is its compact design, as it does not require a lot of space for installation. The valve is generally lightweight, making it easier to handle and install compared to other types of valves. It also provides efficient flow control with a low pressure drop and operates smoothly.
Wafer type butterfly valves are commonly used in various industries such as water treatment, HVAC, chemical processing, and food and beverage. They are suitable for both on/off and throttling applications and can handle a wide range of pressures and temperatures.
Overall, wafer type butterfly valves are cost-effective, versatile, and reliable solutions for controlling fluid flow in a wide range of applications.
