About the Honeywell VFF2FW1YDS

The Honeywell VFF2FW1YDS 2-Way 2 Inch Resilient- Seat Flanged Butterfly Valve is a certified and approved product of Honeywell. This two way valve is ideal for high flow applications and covers a diverse range of applications. The Honeywell VFF2FW1YDS 2-Way 2 Inch Resilient- Seat Flanged Butterfly Valve features a single actuator that synchronizes disc positions, and Nylon coating which offers reduced valve friction. This valve also includes Position indicator and, thanks to the resilient-seat technology offered in many Honeywell valves, the Honeywell VFF2FW1YDS 2-Way 2 Inch Resilient- Seat Flanged Butterfly Valve has a close off rating that has three times the closing force of valves that have been available previously. It gives you the flexibility to decide on the precise, most cost-effective actuator for your application. This product is compact enough to handle easily, and yet engineered for durability and reliability with a high rate of flow capacity and manual or end of line shut off applications. The Honeywell 2-WAY Butterfly Valve will meet and even exceed your HVAC, thermal storage system, chilled water, hot water and cooling tower water application expectations.
