Rapidrop 217 Butterfly Valve (Lugged) 6″ FM Approved, UL listed, VdS

The Rapidrop Fig. 217 is an industrial 6-inch (DN150) lug-type fire protection butterfly valve designed as a system control mechanism with minimized flow restriction and pressure loss when fully opened. Built with a heavy-duty ductile iron lug body featuring threaded inserts around its perimeter, this valve installs directly to matching pipe flanges with individual bolts, making it ideal for dead-end piping networks and down-line maintenance isolation. The valve utilizes a slow-closing worm gear operator running a handwheel mechanism to actively suppress potential line water hammer spikes within the piping. Fluid isolation relies on a premium rubber-encapsulated ductile iron disc, delivering dependable bidirectional, bubble-tight shut-off under standard fire infrastructure working pressures. Suitable for both indoor and outdoor installations across horizontal or vertical configurations, the assembly comes pre-wired with an integrated dual-circuit tamper supervisory switch linked to a 1-meter flying lead for seamless monitoring integration.
