Concentric Butterfly Valve Manufacturer in USA
SVR Global is a top concentric butterfly valve manufacturer in USA, Engineered to API, ASME, and AWWA standards, our valves provide reliable shut-off and throttling performance across municipal and industrial projects.
Concentric butterfly valves are one of the most widely used flow control solutions. With a design that places the disc in the center of the valve body and the seat fully lining the inside diameter, these valves are simple, cost-effective, and ideal for water, air, gas, and low-pressure applications.
What is a Concentric Butterfly Valve?
A concentric butterfly valve is a type of butterfly valve where the stem passes through the centerline of the disc, and the disc sits in the middle of the pipe bore. The seat is elastomeric, ensuring a tight shut-off. These valves are commonly chosen for low-pressure, low-temperature applications, making them a preferred solution for municipal water distribution and HVAC systems.
