Wafer Butterfly Check Valve – DH77X

Home » Types of Check Valve » Wafer Check Valve » Wafer Butterfly Check Valve – DH77X

DH77X wafer butterfly check valve is a type of valve that allows fluid to flow in one direction and prevents backflow in the opposite direction. It consists of a disc that is mounted on a shaft and can rotate around that axis to open or close the valve. The valve is called a “wafer” because it is designed to fit between two flanges and held in place by bolts that pass through the flanges and the valve body.

The advantage of a wafer butterfly check valve is that it is lightweight, compact, and easy to install, making it ideal for applications where space is limited. Additionally, it offers low-pressure drop and good flow control, making it suitable for a variety of industries, such as chemical, food and beverage, water treatment, and HVAC.
