The single flange butterfly valve is a cost-effective, compact and versatile valve suitable for flow control in a variety of industries. Its bidirectional flow capability, easy installation and maintenance, and low pressure drop make it the first choice in systems where space, weight and cost are critical. In addition, it can also be used as an end-of-line valve, adding flexibility to its application.
This type of butterfly valve is commonly used to control fluids in industrial pipelines, especially for large-diameter pipelines (DN600 or greater) and low-pressure systems. They are often used in air ducts, chemical industry, water supply and drainage systems, cooling water systems and several other uses.
Single flange butterfly valves are designed to be easy to install and maintain and are a common choice in many industrial piping systems.
