Honeywell Butterfly Valve, 2 Way, 18 in. - VFF2TV1YPR/M

The Honeywell Butterfly Valve is a 2-way, 18-inch device with a flanged design. A key feature is its impressive flow rate which peaks at 5736 Cv at a 60-degree stroke and 17214 Cv at a 90-degree stroke. The body, constructed of a polyester-coated cast iron for durability and rigidity, is complemented by a resilient seat made of peroxide cured EPDM. This valve also boasts a 416 stainless steel stem for increased strength and stability.

The Butterfly Valve comes in various sizes ranging from 2 to 20 inches, suitable for ANSI Class 125/150 lug pipe connections. It has bi-directional flow capability and includes an extended neck for accommodating 2 inches of pipe insulation.

A notable feature of this valve is its nylon 11 coated, cast iron disks, designed for optimal corrosion resistance, reduced friction, and compatibility with lower-torque actuators particularly with larger valves body sizes. The valve body comes coated in polyester which provides it protection against environmental factors such as weather and UV rays, as well as against chemical exposure, abrasion, and impact. The stainless steel valve stem is designed with a double-D disk connection, boasting a close-tolerance internal structure with no points for corrosion access.

In terms of performance, this valve guarantees 'bubble tight' seat leakage at rated close-off. It is designed for services involving hot water and chilled water-glycol solutions. The flow characteristic is equal percentage, suitable for a wide range of applications. Operating in a wide temperature range from -40 F to 250 F (-40 C to 121 C), it's built to withstand extreme conditions. It also operates effectively up to a ceiling pressure of 150 psi.

Overall, the Honeywell Butterfly Valve is a remarkable combination of power, performance, and durability. It's designed to meet the most demanding industrial applications and environments.
