Honeywell Butterfly Valve, 2 Way, 16 in. - VFF1SV1YDS/M

This Honeywell Butterfly Valve is a two-way, flanged model with a size of 16 inches. The valve touts a hefty 4483 Cv at a 60-degree stroke and 13966 Cv at a 90-degree stroke. The body of the valve is made from cast iron that has been coated with polyester, providing protection against weather, chemicals, ultraviolet rays, abrasion, and impact. The resilient seat is constructed from peroxide-cured EPDM.

The Butterfly Valve accommodates sizes from 2 to 20 inches with ANSI class 125/150 lug pipe connections and offers bi-directional flow. The design features an extended neck that provides room for 2 inches of pipe insulation. It is fitted with Nylon 11 coated, cast iron disks, which guarantee corrosion resistance, reduced friction, and the use of lower-torque actuators with larger valve body sizes.

Moreover, the valve stem is made from 416 stainless steel and comes with a close-tolerance internal double-D disk connection, effectively eliminating points for corrosion access. One of its remarkable features is its ability to maintain bubble tight seat leakage at the rated close-off.

Technical specifications for the Honeywell Butterfly Valve include service for hot water and chilled water-glycol solutions. It provides an equal percentage flow characteristic and operates at a temperature between -40 F (-40 C) and 250 F (121 C). The valve has an impressive close-off pressure of 150 psi, demonstrating its high-quality design and construction.
