80 & 81 Series Resilient Seated Butterfly Valve

The JFlow Controls 80 & 81 Series resilient seated butterfly valve is designed for dependable shutoff and flow control in water, wastewater, gas, HVAC and industrial process applications. The 80 Series features a wafer-style body, while the 81 Series uses a lug-style body.

Available in sizes from 2 to 24 inches, the valve combines a one-piece body, replaceable cartridge-style seat and ISO 5211 direct-mounting pad. Multiple body and seat materials, along with manual and automated operating options, allow the valve to be configured for different media and system requirements.
