The 3-Way Resilient Seated Butterfly Valve 2.5" 2-10VDC is designed for precise control in HVAC applications involving chilled or hot water systems. With a valve body constructed from epoxy powder coated ductile iron (ASTM A536) and a valve disc made of 304 stainless steel, this valve ensures durability and reliability in demanding environments.

Featuring a maximum operating pressure of 232 psi (1600 kPa) and a maximum media temperature of 250 °F (121 °C), this valve is suitable for a variety of applications. The valve's flanged connection type is compatible with ANSI Class 125/150 and is secured using four bolts of 0.625 in size, arranged with a pitch of 11. Additionally, the valve stem is crafted from 416 stainless steel, while the seat is made from EPDM material, contributing to its effective sealing capabilities.

This valve operates with a fail-in-place actuator, designed for NEMA 4X IP66/67 environments, ensuring reliability even in the event of a power failure. The actuator control signal is modulating, allowing for fine adjustments and improved control of fluid flow. Its flow characteristic is modified linear, with a flow coefficient of 75 CV (65 Kvs), allowing for efficient fluid management.

For optimal functionality, it is essential that this valve is not used with steam or fuels, and it accommodates media with up to 60% glycol. The valve's start position is normally closed at Port A, and it has a maximum differential pressure rating of 200 psi (1380 kPa).
