Features
- The FBLC is a resilient-seated concentric butterfly valve with a pinless disc design that eliminates the corrosion and leakage path associated with conventional pin/stem connections
- The EPDM seat is moulded integrally into the body, providing a positive bubble-tight seal
- Fusion-bonded epoxy coating provides corrosion protection for buried or wet-well service
- Available with handwheel, gearbox or electric actuator
