Honeywell Ball Valve, 3 Way, 4 in. 254 Cv - VBF3J21SRD/M

The product is a Honeywell 3-Way Ball Valve with a 4-inch aperture, offering a Cv value of 254. This device is constructed with a cast-iron body for durability and features a Teflon seat and a 316-grade stainless steel stem, ensuring reliable operation in differing conditions. Dimensions range from 4 to 6 inches and it comes with ANSI Class 125 flanged connections.

An additional feature is the removable manual operating handle which provides the ability to control the valve during installation or during power failures. The unit can be field configured for either a normally open or normally closed fail-safe position depending on specific requirements.

For versatility in placement and weather resistance, an optional NEMA 3R (IP54) rated enclosure is available enabling its use in outdoor applications. Users can choose from four different actuator mounting positions on the valve providing optimal flexibility. The ball valve offers a wide range of Cv options between 91 to 650.

The design implements a globe valve A-B-AB flow pattern with a Side B Port. It's purposed to service hot and chilled water systems infused with up to 50% glycol solutions. The flow characteristic transitions from Port A to AB, exhibiting an equal percentage, while Port B to AB showcases a linear pattern with a 20% reduced flow capacity. The valve maintains a resilient operating temperature range of -22 F to 250 F (-30 C to 121 C) and has a close-off pressure of 70 psi.
