Honeywell Butterfly Valve, 2 Way, 4 in. - VFF1JW1YXS/M

The Butterfly Valve, 2 Way, 4 in., is a highly efficient, flanged valve designed to offer streamlined control in industrial applications. It boasts an impressive Cv of 274 at a 60-degree stroke and an even higher Cv of 841 at a 90-degree stroke, ensuring optimal control. This product is expertly constructed from a polyester-coated cast iron body, fortified to offer resistance against chemicals, weather, UV radiation, abrasion, and impact.

Inside, the valve reveals a resilient seat made from peroxide-cured EPDM and a stem made from 416-grade stainless steel. These ensure the valve's high performance and durability. The 2-way butterfly valve includes ANSI Class 125/150 lug pipe connections, ranging in size from 2 to 20 inches, facilitating bi-directional flow.

The valve features an extended neck that allows for 2 inches of pipe insulation and is enhanced with nylon 11 coated cast iron disks. This coating provides corrosion resistance, reduces friction, and enables the use of lower-torque actuators with larger valve body sizes.

The stainless steel stem of the valve also features a close-tolerance internal double-D disk connection. This element blocks any points that could potentially facilitate corrosion access. The valve demonstrates exceptional tight seat leakage at its rated close-off, creating an efficient seal.

This variety of butterfly valve is suitable for both hot water services and chilled water-glycol solutions, with an equal percentage flow characteristic. Furthermore, it enables an operating temperature range of -40°F to 250°F (-40°C to 121°C), testament to its diverse functionality. Lastly, it can combat a close-off pressure of 175 psi, making it a potent and reliable tool in a wide range of industrial scenarios.
