Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JV1YXS/M

The product, titled Butterfly Valve, is a two-way system with a diameter of 4 inches. It's a flanged design with 274 Cv at a 60-degree stroke and 841 Cv at a 90-degree stroke. The valve body is made of cast iron and is coated with polyester to ensure resilience. The seating comprises of peroxide cured EPDM, while the valve stem is made of 416 stainless steel for optimum performance.

This Butterfly Valve offers sizes from 2 to 20 inches and features ANSI Class 125/150 Lug Pipe connections. It provides a bidirectional flow with an extended neck for accommodating 2 inches of pipe insulation. The valve disks, made of cast iron, are coated with Nylon 11 to enhance corrosion resistance, reduce friction, and enable the use of lower-torque actuators with larger valve body sizes.

Notably, the cast iron valve body is prepared with a protective coat of polyester. This coating offers resistance against weather, chemical exposure, ultraviolet rays, abrasion, and impacts. The stainless steel valve stem comes with a close-tolerance internal double-D disk connection that prevents corrosion access. Moreover, its seat leakage is bubble tight at the rated close-off.

This butterfly valve is designed for services involving hot water and chilled water-glycol solutions. It provides an equal percentage flow characteristic and is capable of operating within a wide temperature range of -40 F to 250 F (-40 C to 121 C). Its maximum close-off pressure capacity is 175 psi, showcasing the excellent strength and reliability of the valve.
