Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JW1YXA/M

The Honeywell Butterfly Valve, a 2-Way, 4 inch control mechanism, comes with a flanged design with a calculated Cv of 274 at a 60-degree stroke and 841 at a 90-degree stroke. It features a polyester-coated cast iron body, enhancing its resistance to adverse weather conditions, chemicals, ultra-violet exposure, abrasion, and impact. The valve seat is furnished with peroxide-cured EPDM, ensuring resilient performance.

The product is offered in a diverse range of sizes from 2 to 20 inches, featuring ANSI Class 125/150 lug pipe connections. It is designed to allow bi-directional flow and comes with an extended neck that accommodates up to 2 inches of pipe insulation, making it a flexible component in various industrial settings.

The product is built with cast iron disks which are coated with Nylon 11. This coating optimizes corrosion resistance, minimizes friction, and allows the use of lower-torque actuators with larger valve body sizes. The valve stem, constructed from 416 stainless steel, has a close-tolerance internal double-D disk connection, eliminating potential spots that may allow corrosion.

The valve is built to ensure bubble-tight seat leakage at the rated close-off, guaranteeing reliable performance under anticipated conditions. The valve is engineered to service both hot water and chilled water-glycol solutions, providing a flow characteristic of equal percentage. With an operating temperature range of -40 F to 250 F (-40 C to 121 C), this valve can withstand extreme conditions. The valve is designed to handle a close-off pressure of up to 175 psi, demonstrating its robust and durable nature.
