Belimo Hydronic Simulator Tool
Educational Tool on the Importance of PI valves
The Belimo Hydronic Simulator™ is a tool that simulates a hydronic system in a 4-story building with five terminal units on each floor. All terminal units, branches, and the raiser have a manual balancing valve that adjusts based on the valve opening. The Simulator identifies and illustrates when the system needs to be balanced and how adjusting the valve could impact the entire system. The primary purpose of the Belimo Hydronic Simulator is to educate on why pressure-dependent valves are not recommended in a dynamic system.

Pressure Independent Control Valves
Belimo PIV Energy Modeling Tool
Now Available as a Standalone Windows Application
The PIV Energy Modeling Tool calculates the energy savings when using Pressure Independent Characterized Control Valves (PICCV) and Electronic Pressure Independent Valves (ePIV) in comparison to pressure dependent valves (Characterized Control Valves (CCV) or globes).
- Minimum variables are needed to obtain a quick comparison of energy usage
- Uses hourly calculations in the background to obtain the different HVAC loads with predefined building types along with weather data and climate zone
- Provides calculation tables to enable modeling as part of an Exceptional Calculation Method
- Complies with ASHRAE 90.1-2010 Appendix G regarding requirements for simulation programs
