Frequently Asked Questions
What is a wafer butterfly valve and how does it differ from other butterfly valve types?
A wafer butterfly valve is designed to fit between two pipe flanges using bolts that pass through the valve body. It is more lightweight, compact, and cost-effective compared to lug-style or flanged valves, making it ideal for tight spaces.
What temperature range is suitable for this wafer butterfly valve?
This valve operates efficiently within a range of -20°C to 120°C, suitable for water supply, heating, and HVAC systems.
What sealing performance does this butterfly valve offer?
It achieves a zero-leakage sealing grade with bidirectional capabilities. Its concentric structure ensures a tight seal under various pressures.
What drive and actuation options are available?
It supports manual handles, worm gear transmission, electric, pneumatic, and hydraulic actuators for both local and automated remote operation.
In which industries can this wafer butterfly valve be applied?
It is widely applied in water treatment, drainage, HVAC, chemical processing, and food industries, especially for non-corrosive media.
What are the available connection methods for installation?
It supports four main methods: flange connection, clamp connection, butt welding, and lug clamp connection.
