Description
Butterfly wafer type are compact flow control devices used in industrial applications. They are designed to regulate or isolate the flow of liquids or gases in pipelines. These valves have a lightweight construction, allowing them to be installed between flanges without additional support.Comprising a disc, stem, body, and actuator, these valves offer efficient operation. The disc, connected to the stem, rotates within the valve body to control the flow. Ideal for industries such as water treatment, chemical processing, and more.These valves are widely used in applications requiring high flow rates and low-pressure conditions.

Features
1.Compact and Lightweight Design: Butterfly wafer type have a compact design, making them space-efficient and easy to install between flanges.
2.Excellent Flow Control: Wafer type butterfly valves provide excellent flow control capabilities with low-pressure drop. The disc design allows for unrestricted flow when fully open, minimizing turbulence and pressure loss.
3.Quick and Responsive Operation: These valves are designed for fast response times, allowing for quick opening and closing.
4.Low Maintenance Requirements: With fewer moving parts and a robust construction, It generally have lower maintenance needs.
FAQ
Q: What is the working principle of a wafer type butterfly valve?
A: The working principle involves a disc that rotates within the valve body to control the flow of fluids or gases. When the disc is perpendicular to the flow direction, it blocks the flow, and when it is parallel, it allows the flow to pass through.
Q: Is it suitable for high temperature applications?
A: Yes, It is available in a high temperature model designed to withstand high temperatures.
Q: How do I select the appropriate size for my application?
A: To select the appropriate size, you need to consider the pipe diameter and flow requirements of your application. The valve size should match the pipe size to ensure optimal flow control.
Q: Can these valves be installed in any orientation?
A: It can typically be installed in any orientation, as long as the flow direction indicated on the valve body is aligned correctly with the pipeline.
