Honeywell Butterfly Valve, 2 Way, 20 in. - VFF2UW1YXR/M

The Honeywell Butterfly Valve is a 2-way device with a 20-inch diameter. Crafted from durable, polyester-coated cast iron, this valve features a size range of 2 to 20 inches with ANSI Class 125/150 lug pipe connections. The Cv is 7144 at a 60-degree stroke and 22339 at a 90-degree stroke. It also includes a peroxide cured EPDM resilient seat and a 416 stainless steel stem.

Impressive features of this valve include its bi-directional flow, an extended neck for 2 inches of pipe insulation, and nylon 11 coated, cast iron disks. The latter ensures corrosion resistance, reduced friction, and the ability to utilize lower-torque actuators with larger valve body sizes. The valve body itself is polyester-coated cast iron, providing enhanced protection against weathering, chemicals, UV rays, abrasions, and impact.

Further adding to its robust nature, the stainless steel valve stem has a close-tolerance internal double-D disk connection, eliminating chances for corrosion access. It guarantees bubble-tight seat leakage at the rated close-off. As for its technical specifications, this valve is designed for services involving hot water and chilled water-glycol solutions having an equal percentage flow characteristic. With an operating temperature range from -40 F to 250 F (-40 C to 121 C) and a close-off pressure of 150 psi, this Butterfly Valve from Honeywell exemplifies efficiency and resilience while ensuring streamlined industrial operations.
