Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JW1YCS/M

The Honeywell 2-Way, 4-inch Butterfly Valve boasts a flanged, polyester-coated cast iron body, suitable for orchestrating bi-directional flow control within industrial automation systems. It aligns well with American National Standards Institute (ANSI) Class 125/150 lug pipe connections, ranging sizes from 2 to 20 inches. The innovative valve design includes an extended neck to accommodate 2 inches of pipe insulation.

This robust controller displays a flow coefficient (Cv) of 274 at a 60-degree stroke and 841 at a 90-degree stroke. For enhanced resilience, it comes furnished with a peroxide-cured Ethylene Propylene Diene Monomer (EPDM) seat and a reinforced 416 stainless steel stem. The stem also introduces an intricate internal double-D disk connection, ensuring tight sealing with no points for corrosion access.

Contributing to its durability are the Nylon 11 coated, cast iron disks offering substantial corrosion resistance, friction reduction, and utilization of lower-torque actuators with larger valve body sizes. The valve body itself is safeguarded with a polyester coating to provide thorough resistance against weathering, chemical reactions, ultraviolet radiation, abrasion, and mechanical impacts.

The valve is engineered for services involving hot water and chilled water-glycol solutions and exhibits equal percentage flow characteristics. It can seamlessly operate over a wide temperature range, from -40 F to 250 F (-40 C to 121 C). Easily maintainable, the controller ensures bubble-tight seat leakage at its rated close-off pressure of 175 psi, providing uncompromised, stable performance under varying conditions.
