Honeywell Butterfly Valve, 2 Way, 10 in. - VFF2NW1YDR/M

The Honeywell Butterfly Valve is a robust 2-way valve with a size range of 10 inches. It is characterized by an enormous Cv capacity - 1710 at a 60-degree stroke and 5430 at a 90-degree stroke. For maximum durability, the valve body is crafted from cast iron and coated with polyester, affording it excellent protection against fluctuating weather conditions, chemicals, abrasive forces, ultraviolet radiation, and impact. The valve's seat is engineered from peroxide-cured EPDM, an attribute that grants it remarkable resilience.

This Butterfly Valve’s design incorporates a 416 stainless steel stem and has the unique capacity to accommodate ANSI class 125/150 lug pipe connections, an element that sets it apart for its size range of 2 to 20 inches. It possesses a bi-directional flow mechanism and features an extended neck that allows for 2 inches of pipe insulation.

The disks used in this valve are cast iron and coated with Nylon 11, promoting corrosion resistance and reduced friction, making it suitable for use with lower-torque actuators for larger valve body sizes. The stainless-steel valve stem, with its closely-toleranced internal double-D disk connection, offers no points for corrosion access while maintaining a bubble-tight seat leakage at rated close-off.

The operational specifications of this valve make it adept at handling service with both hot water and chilled water-glycol solutions. It exhibits an equal percentage flow characteristic and can operate in temperatures ranging from -40 F to 250 F (-40 C to 121 C). With a close-off pressure of 175 psi, this Honeywell Butterfly Valve encompasses all the necessary features and capabilities to meet the high demands of industrial control systems.
