AABC to Hold TAB Talk Webinar on Pressure Independent Valve Technology

The Associated Air Balance Council will hold a new AIA-approved webinar in their TAB Talk series on May 19, in collaboration with the newest AABC Industry Partner, Belimo.

Pressure independent valves are commonly used in the HVAC industry to control chilled and hot water for air conditioning and heating. PI valves supply a specific flow for each value of the DDC control signal, regardless of pressure variations in the system. The speakers will discuss valve characteristics and how they relate to hydronic coil performance, valve sizing and valve authority, and how these elements affect the equipment’s operation in the central energy plant. The session will conclude with a review of the different types of pressure independent valves and valve technologies.
