Honeywell Butterfly Valve, 2 Way, 4 in. - VFF1JV1YDS/M

The Honeywell Butterfly Valve is a 2-way, 4-inch valve designed to facilitate control and distribution of liquid media. Its flanged design is characterized by a flow coefficient (Cv) of 274 at a 60-degree stroke and 841 at a 90-degree stroke. The valve boasts a cast iron body embellished with a polyester coating and a peroxide-cured EPDM resilient seat for robustness and longevity.

Constructed to accommodate pipe sizes ranging from 2 to 20 inches, the valve adheres to ANSI Class 125/150 lug pipe connections for guaranteed compatibility and effective bidirectional flow buoyancy. An extended neck design allows for the incorporation of 2 inches of pipe insulation for enhanced thermal efficiency.

Further augmenting its durability against corrosion is the inclusion of Nylon 11 coated, cast iron disks. This intricate design element minimizes friction, thereby reducing the requirement for higher-torque actuators, particularly with larger valve body sizes. The valve body also sports a weather, chemical, ultra-violet, abrasion, and impact protective polyester coat, ensuring its resilience in challenging environments.

Further refinement is found in the stainless steel stem comprising a close-tolerance internal double-D disk connection. This well-engineered detail detracts potential points of corrosion, ensuring the valve's performance over time. The valve also guarantees bubble-tight seat leakage at its rated close-off, offering solid control during operation.

The valve is customarily deployed for service involving hot water and chilled water-glycol solutions distinctively exhibiting an equal percentage flow characteristic. Its working temperature varies from -40 degrees Fahrenheit to 250 degrees Fahrenheit equivalent to -40 degrees Celsius to 121 degrees Celsius. With a close-off pressure of 175 psi, the Honeywell Butterfly Valve exemplifies steadfast efficiency and reliability.
