Rapidrop 212 Butterfly Valve (Grooved) 8″ FM Approved, UL Listed

The Rapidrop Fig. 212 is an industrial 8-inch (DN200) grooved-end fire protection butterfly valve designed as a system control mechanism with minimized flow restriction and pressure loss when fully opened. Constructed from high-strength ductile iron, it features a slow-closing worm gear operator running a handwheel mechanism to actively suppress potential line water hammer spikes. Fluid sealing relies on a heavy-duty, EPDM rubber-encapsulated ductile iron disc, delivering dependable bidirectional, bubble-tight shut-off under standard fire infrastructure working pressures. Built for indoor and outdoor installations across horizontal or vertical configurations, the valve assembly is finished with a corrosion-resistant epoxy layer and comes equipped with an integrated dual-circuit tamper supervisory switch linked to a 1-meter flying lead for seamless monitoring integration.
