Honeywell Butterfly Valve, 2 Way, 4 in. - VFF1JW1YPS/M

The Butterfly Valve, 2 Way, 4 in. model from Honeywell is a high-performance control system featuring a flanged design with a Cv of 274 at a 60-degree stroke and a Cv of 841 at a 90-degree stroke. Its sturdy form consists of a polyester-coated cast-iron body, which offers robust weather, chemical, ultraviolet, abrasion, and impact protection. This model accommodates sizes from 2 to 20 inches with ANSI Class 125/150 lug pipe connections and a bidirectional flow.

The valve's seat is equipped with peroxide-cured EPDM for enhanced resilience and the stem is crafted from 416 stainless steel with a close-tolerance internal double-D disk connection, making it impervious to corrosion. Additionally, it provides a bubble-tight seat leakage at the rated close-off. The extended neck allows for 2 inches of pipe insulation.

The valve's disks are coated with Nylon 11, enabling corrosion resistance, reduced friction, and the facilitation of lower-torque actuators with larger valve body sizes. The butterfly valve serves hot water and chilled water-glycol solutions, evidencing an equal percentage flow characteristic. Its operating temperature ranges from -40 F to 250 F (-40 C to 121 C) and it manages a close-off pressure of 175 psi to ensure efficient and effective operation in various industrial settings.
