Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JW1YDR/M

The Honeywell 4-inch, 2-way Butterfly Valve is a high-performing, resilient product that can handle a host of applications. Equipped with ANSI Class 125/150 lug pipe connections, it accommodates sizes ranging from 2 to 20 inches for versatile use. The product implements bi-directional flow and features an extended neck allowing for accommodation of 2 inches of pipe insulation.

The valve comprises a polyester-coated cast iron body capable of enduring environmental elements, UV exposure, chemical reaction, and physical impacts. This extends the valve's longevity and increases its resistance to corrosion. The same resilience is found in the valve's disk, which is constructed from Nylon 11 coated cast iron. This design minimizes friction and allows to integrate lower-torque actuators with bigger valve body sizes, increasing efficiency.

The product's 416 stainless steel stem is designed with a close-tolerance internal double-D disk connection, eliminating potential corrosion hotspots. Thanks to its peroxide-cured EPDM resilient seat, it ensures tight seat leakage at the rated close-off.

In terms of service, this valve operates effectively with hot water and chilled water-glycol solutions. It exhibits an equal percentage flow characteristic and can function within a wide range of temperatures, from as low as -40 F (-40 C) to as high as 250 F (121 C). Finally, it can withstand a close-off pressure of up to 175 psi.

In conclusion, Honeywell's 4-inch, 2-way Butterfly Valve provides long-lasting, efficient control suitable for a variety of industrial applications.
