Industrial Lug Butterfly Valve

1. This kind of butterfly valves are designed to provide years of rugged durability at a competitive value. 

2. Built for HVAC, utility, commercial and general industrial applications and media, these valves offer many more years of performance over lightweight throwaway valves. 

3. The movement of the elastomer against the body assures a completely dry back.

4. Wide flange=face sealing area provides a tight flange-to-valve seal without the use of gaskets.

5. The controlled-torque Seat allows tight shut-off with minimum movement of the seat material to reach the closed position in the center of the seat for ease of actuation.

6. The wide sealing area around the shaft provides a positive self isolating the shaft form the media.
