Honeywell Butterfly Valve, 2 Way, 4 in. - VFF1JW1YES/M

The Honeywell Butterfly Valve, a 2-way and 4-inch control device, is equipped with features designed for efficiency and durability. It bears an impressive Cv of 274 at a 60-degree stroke, extending up to 841 Cv at a 90-degree stroke. Constructed with polyester-coated cast iron, it ensures resilience amidst various environmental conditions. The valve also includes a seat made from peroxide cured EPDM, enhancing its longevity. It features a 416 Stainless Steel Stem, upholding its robustness.

The Butterfly Valve can accommodate sizes ranging from 2 to 20 inches with ANSI Class 125/150 lug pipe connections. This range, coupled with its feature of bi-directional flow, supports versatile and refined control in various industrial applications. The device is designed with an extended neck enabling an additional 2 inches of pipe insulation for improved efficiency.

Corrosion resistance and reduced friction are ensured by the nylon 11 coated, cast iron disks. This design facilitates the use of lower-torque actuators with larger valve body sizes. The valve body, also composed of cast iron, is polyester-coated to provide resistance against weather, chemical, ultra-violet exposure, abrasion, and impact damage. The stainless steel valve stem is designed with a close-tolerance internal double-D disk connection, eliminating potential points for corrosion access. Users can also rely on tight seat leakage when the valve is at the rated close-off.

The Butterfly Valve is best suited for services involving hot water and chilled water-glycol solutions due to its equal percentage flow characteristic. It operates effectively even under extreme temperature conditions ranging from -40°F to 250°F (-40°C to 121°C). The device has a close-off pressure specification, handling up to 175 psi.
