Description
The Belimo B217+TFRB24 2-Position Spring Return Characterized Control Valve 3/8 4.7Cv is used to control heating or cooling in HVAC systems, by adjusting fluid flow through it, either open or closed on a control signal. It uses a spring-return actuator that runs on 24 volts to move the stainless-steel valve plug between two positions, allowing on/off control with a specific flow pattern. It is intended to be used in residential and commercial HVAC equipment such as hydronic heating, chilled water and air handling elements, and fits directly to 3/4″ NPT piping. It assists in balancing flow-coordinated temperature control.
