Rapidrop 216 Butterfly Valve (Grooved) 6″ FM Approved, UL listed, VdS, Gost

The Rapidrop Fig. 216 is an industrial 6-inch (DN150) grooved fire protection butterfly valve designed as a system control mechanism with minimized flow restriction and pressure loss when fully opened. Built with a robust ductile iron body configured with standard mechanical grooved ends, it connects securely into piping systems without the need for flanging or welding tools. 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. Suitable for both indoor and outdoor installations across horizontal or vertical configurations, the assembly is finished with a corrosion-resistant layer and comes pre-wired with an integrated dual-circuit tamper supervisory switch linked to a 1-meter flying lead for seamless monitoring integration.
