Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JW1Y2A/M

The Honeywell Butterfly Valve, a 2-way valve with a diameter of 4 inches, is uniquely constructed with a polyester-coated cast iron body, which provides superior protection against weather, chemical reactions, ultraviolet rays, abrasions, and impacts. The valve encompasses a variety of innovative features such as the peroxide-cured EPDM resilient seat, the 416 stainless steel stem, and leakage protection contributing towards its high performance. The valve offers an impressive Cv of 274 at a 60-degree stroke and 841 at a 90-degree stroke.

Available in sizes ranging from 2 to 20 inches, these valves accommodate ANSI class 125/150 lug pipe connections and ensure bi-directional flow. With an extended neck that accommodates up to 2 inches of pipe insulation, this product ensures minimal heat loss or gain. Further, the cast iron disks, adorned with Nylon 11 coating, not only offer superior corrosion resistance but also reduce friction, supporting the use of lower-torque actuators with larger valve body sizes. The stainless steel valve stem is engineered with a close-tolerance internal double-D disk connection that eliminates potential points for corrosion access.

The Butterfly valve guarantees bubble-tight seat leakage at its rated close-off pressure, offering the perfect solution for hot water and chilled water-glycol solutions. The product’s flow characteristic is defined by an equal percentage principle. As for its operating temperature, the valve can seamlessly function within a range of -40 F to 250 F (-40 C to 121 C) and can effectively handle close-off pressures up to 175 psi.
