Honeywell Butterfly Valve, 2 Way, 6 in. - VFF2LW1Y2A/M

The Honeywell Butterfly Valve, a 2-way, 6-inch device, boasts a flanged construction with a Cv of 567 at a 60-degree stroke and a Cv of 1850 at a 90-degree stroke. Its body is made from cast iron coated with polyester, adding a layer of resistance to weather, chemical, ultraviolet, abrasion, and impact threats. The resilient seat is formed from peroxide-cured EPDM, while the stem is crafted from 416 stainless steel.

The valve accommodates sizes ranging from 2 to 20 inches and makes use of ANSI Class 125/150 lug pipe connections. It offers the advantage of bi-directional flow, and possesses a nylon 11-coated, cast iron disk that bolsters its corrosion resistance, reduces its friction, and permits the utilization of lower-torque actuators with larger valve body sizes. The extended neck allows for 2 inches of pipe insulation.

The valve's stem, created with stainless steel, showcases a close-tolerance internal double-D disk connection, a design that eliminates points for corrosion access. The device ensures bubble-tight seat leakage at rated close-off. In terms of service, the valve is suitable for both hot water and chilled water-glycol solutions, featuring an equal percentage flow characteristic. Additionally, it operates effectively within a temperature range of -40 F to 250 F (-40 C to 121 C) and can handle a close-off pressure of 175 psi.
