Flowserve Corporation IBN3RS SLIMSEAL SS Butterfly Valve

Flowserve Serck Audco Slimseal SS butterfly valve, 3 in (76 mm), is a wafer-type, lined butterfly valve designed for corrosive chemical service and hygienic applications. It uses an integrally molded elastomer body liner that lasts through the valve life and reduces maintenance, paired with a triple-seal design and live-loaded shaft seal to prevent ingress of contaminants. Seating options include nitrile (NBR), EPDM, Viton (FKM), and White Nitrile, enabling compatibility with a broad range of fluids. The Slimseal family covers DN 50 to 600 (NPS 2 to 24), supports PN10 to PN20 (Class 125 to 150), and operates from -10°C to 140°C, making it suitable for demanding process environments. This valve features a gasket-integrated body and liner that protects the seats during installation and simplifies maintenance, reflecting Flowserve’s emphasis on reliable performance in corrosive and hygienic service scenarios.
