Honeywell Butterfly Valve, 2 Way, 8 in. - VFF1MV1YPS/M

The Butterfly Valve, 2 Way, 8 inch, from Honeywell features a flanged design with varying Cv values of 1081 at a 60-degree stroke and 3316 at a 90-degree stroke. Its robust body is composed of polyester coated cast iron, ensuring high resistance against weather, chemical reactions, ultraviolet light, abrasion, and physical impact. The valve also features a resilient seat constructed from peroxide cured EPDM, along with a 416 stainless steel stem.

Applicable for a range of pipe sizes between 2 to 20 inches, this Butterfly Valve comes with ANSI Class 125/150 lug pipe connections. It supports bi-directional flow, and includes an extended neck for accommodating up to 2 inches of pipe insulation. The valve's disks are crafted from nylon 11 coated cast iron, providing excellent resistance against corrosion, reducing friction, and allowing for the use of lower-torque actuators with larger valve body sizes.

Further enhancing its corrosion resistance, the stainless steel valve stem of this Butterfly Valve incorporates a close-tolerance internal double-D disk connection, which doesn't provide any points for corrosion access. The valve offers bubble-tight seat leakage at rated close-off.

In terms of technical specifications, this Butterfly Valve is ideal for hot and chilled water-glycol solutions, and showcases an equal percentage flow characteristic. It operates efficiently with a temperature range of -40 degrees Fahrenheit to 250 degrees Fahrenheit (-40 degrees Celsius to 121 degrees Celsius). The highest close-off pressure that it can handle is 175 psi.
