Series 300 Resilient Seated Butterfly Valve

Brand: Av-Tek
Add Product to My Catalog

Av-Tek® Resilient Seated Butterfly Valves are ideal for general service applications, such as fire protection, water treatment, cooling systems, air control, and many other industrial uses. 

Additionally, you'll find our Resilient Seated Butterfly Valves provide a long service life without sacrificing ease of operation and maintenance. 

Lug style butterfly valves can be used as a stopper and tap for discharging at the end of lines.
Features
  • Replaceable resilient seat can be easily removed and replaced without the need of special tools, or excessive downtime
  • The molded in O-ring seat design serves as flange seals, eliminating the need for gaskets between the flanges and the valve
  • The disc is not penetrated by a pin or bolt to secure it into place; thus, increasing its strength while reducing potential failures
  • Resilient seats help provide bi-directional, zero leakage shut off. This design totally isolates the valve body and stem from the line media
  • NSF Approved Fusion Bonded Epoxy (FBE) Coatings and linings
  • The lugged body design comes drilled, tapped, and is fully rated to line pressure, even if there is only a counter flange on the downstream side of the valve
  • A round disc hub provides complete concentric seating with minimal flow restriction, resulting in lower torques
  • A Carbon Steel, PTFE lined, upper bearing ensures low friction and torque while operating the valve on smaller diameter valves (8">)
  • ISO mounting flanges are an integral part of the body and are standardized to allow direct mounting to many types of actuators
