Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JV1Y8P/M

The product titled Butterfly Valve, 2 Way, is a 4-inch Flanged device designed with a Cv of 274 at a 60-degree stroke. Engineered with a high-quality, polyester-coated cast iron body, the valve features a peroxide-cured EPDM resilient seat and a robust 416-grade stainless steel stem.

The Butterfly Valve offers versatile sizes from 2 to 20 inches, compliant with ANSI Class 125/150 lug pipe connections. It permits bi-directional flow and has an innovative extended neck design that accommodates 2 inches of pipe insulation—tailored for superior functionality. This model's disks are fabricated from cast iron, boasting a protective Nylon 11 coating that enhances the valve’s resistance to corrosion, reduces friction, and facilitates the use of lower-torque actuators with larger valve body sizes.

The cast iron valve body is meticulously coated with polyester to offer substantial protection against a variety of environmental factors such as weather, chemicals, ultraviolet exposure, abrasion, and impact. Further enhancing the valve's resilience, the stem is manufactured with polished stainless steel and features a close-tolerance internal double-D disk connection, eliminating potential points for corrosion accessibility.

This valve ensures a bubble-tight seat leakage at the rated close-off. The device is serviceable with hot water and chilled water-glycol solutions and provides an equal percentage flow characteristic. Its efficient operating temperature spans from -40 degrees Fahrenheit to 250 degrees Fahrenheit (-40 degrees Celsius to 121 degrees Celsius), capable of maintaining a close-off pressure of 175 psi.
