UL/FM ductile iron butterfly valve is designed specifically to meet the rigorous requirements of automatic sprinkler systems. The unique EPDM molded-in seat liner with ductile iron disc provides bubble-tight shutoff at rated pressure. These valves are installed and monitored in fire protection applications where they remain in the normally closed position. A typical application would be fire pump test bypass lines. With the internal stem/disc geometric drive design there is no need for pins or bolts that may create leak paths or turbulence in the waterway
