Honeywell Butterfly Valve, 2 Way, 4 in. - VFF2JW1YDS/M

The Honeywell Butterfly Valve (2-way, 4 in.) is designed with a flanged structure and exhibits a Cv of 274 at a 60-degree stroke and 841 at a 90-degree stroke. The valve body is built with robust polyester-coated cast iron which effectively withstands hazardous weather, chemical exposure, ultraviolet rays, abrasion, and impact. It is equipped with a peroxide-cured EPDM resilient seat adding to its durable characteristics. Additionally, its 416 stainless steel stem with a double-D disk connection has been refined to closely tolerate internal aspects, eliminating points for potential corrosion access.

The valve provides bi-directional flow with ANSI Class 125/150 lug pipe connections ranging from 2 to 20 inches. The extended neck allows for two inches of pipe insulation to be added. The valve disks, fashioned from nylon 11 coated, cast iron material, afford corrosion resistance, reduced friction, and pave the way for the use of lower-torque actuators with larger valve body sizes.

This well-engineered butterfly valve is ensured of bubble-tight seat leakage at a rated close-off. Its preferred service consists of hot water and chilled water-glycol solutions, with an equal percentage flow characteristic. The Honeywell Butterfly Valve has been tested to operate efficiently within a temperature range of -40°F to 250°F (-40°C to 121°C) and upholds a close-off pressure of 175 psi. It exemplifies Honeywell's commitment to efficient, secure, and reliable industrial automation and control systems.
