CONCENTRIC BUTTERFLY VALVE
2"–48", Class 125–150 soft-sealing concentric butterfly valve with bi-directional sealing and light-weight design.
Product Details
OVERVIEW
Concentric butterfly valves are soft-sealing elastic seat-type midline valves designed for switching and regulating fluid flow. With the stem centered in the disc and the disc centered in the bore, these valves offer a symmetric design that delivers bi-directional sealing performance. The rubber-covered valve body provides complete isolation of the medium from metallic components, making them suitable for corrosive service conditions.
Available from 2" to 48" in Class 125–150, these valves conform to API 609 and are supplied with genuine raw materials, material test certificates (MTC 3.1), and hydraulic test certificates. Their light weight and low cost make them a practical alternative to gate valves in water treatment, HVAC, and general industrial fluid control.
