Honeywell Butterfly Valve, 2 Way, 4 in. - VFF1JV1YPS/M

Introducing the Honeywell Butterfly Valve, a robust 2-way, 4-inch valve designed for efficient functionality and logevity. This valve boasts a formidable CV of 274 at a 60-degree stroke and 841 at a 90-degree stroke. It features resiliency through its peroxide-cured EPDM seat and durability via its 416 stainless steel stem. The valve's body is made from a polyester-coated cast iron, providing superior weather, chemical, UV, abrasion, and impact protection.

The Butterfly Valve from Honeywell is available in sizes ranging from 2 to 20 inches, accommodating ANSI class 125/150 lug pipe connections. Offering bi-directional flow, the valve is equipped with an extended neck to allow for 2 inches of pipe insulation. Another unique feature is its Nylon 11 coated, cast iron disks, which not only ensure corrosion resistance, but they also minimize friction and allow for the utilization of lower-torque actuators with larger valves body sizes.

Adding to its list of superior features, the valve stem is made from stainless steel and it's equipped with a close-tolerance internal double-D disk connection, leaving no points for corrosion access. This ensures a smooth operation with bubble-tight seat leakage at rated close-off.

As for technical specifications, the Butterfly Valve is primarily designed for services involving hot water and chilled water-glycol solutions. It offers an equal percentage flow characteristic, and can operate reliably in temperatures ranging from -40 F to 250 F (-40 C to 121 C). The valve can comfortably withstand a close-off pressure of up to 175 psi.

In essence, the Honeywell Butterfly Valve is an exemplary mix of design innovation, functionality, and robustness, suitable for a variety of industrial automation and control systems.
