Rapidrop 213 Butterfly Valve (Wafer) 8″ FM Approved, UL listed

The Rapidrop Fig. 213 is an industrial 8-inch (DN200) wafer-type fire protection butterfly valve designed as a system control mechanism with minimized flow restriction and pressure loss when fully opened. Built with a compact, sandwich-style wafer body to fit securely between standard mating flanges without the need for additional flange gaskets, its ductile iron construction provides excellent high-pressure structural integrity. 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 heavy-duty, EPDM rubber-encapsulated ductile iron disc, delivering dependable bidirectional, bubble-tight shut-off under standard fire infrastructure working pressures up to 20.7 bar (300 psi). Suitable for both indoor and outdoor installations across horizontal or vertical configurations, the assembly is finished with a corrosion-resistant fusion-bonded epoxy layer and comes pre-wired with an integrated dual-circuit tamper supervisory switch linked to a 1-meter flying lead for seamless monitoring integration.
