Fundamentals and Applications
Chair:
Robert C. Walker, Belimo Aircontrols Usa
Technical Committee: 6.1 Hydronic and Steam Equipment and Systems
CoSponsor: 1.4 Control Theory and Application
This seminar presents an overview of hydronic control valve sizing with special emphasis on sizing issues which can affect the performance of the control valves. Actual examples of incorrect valve sizing will be shown with an explanation of the problems caused and the solutions required to correct the problems.
1 Basics of Hydronic Control Valve Sizing
This session discusses the correct method of sizing hydronic control valves. Included will be a discussion of valve specification terminology, formulas for valve sizing, pipe geometry factors, and valve authority.
2 Hydronic Valve Sizing: Behind the Curtain
This session presents hydraulic modeling and case studies providing examples of the effects of incorrect control valve sizing that have negatively impacted the hydronic system as well as design strategies that impact system performance and control valve operation.
