Tecofi balancing valves
A balancing valve lets you measure and set the flow and pressure of each branch so that a heating or cooling system (chillers, FCUs) delivers the design heat to every point. Tecofi lists RC2152 with a bronze body and BSP threads (DN15 to DN50, 25 bar), and RC4240, RC4241 and RC4251 with ductile iron bodies and flanges (PN16 or PN25, two steel pressure test points).
| Model | Materials | Connection | Working pressure | Working temperature |
|---|---|---|---|---|
| RC2152 | CC 491 K bronze body; DZR brass disc; DZR brass pressure test points | BSP female, DN15 to DN50 | 25 bar | -10°C to +120°C |
| RC4240 / RC4241 / RC4251 | GGG40 ductile iron body and bonnet; ductile iron disc with EPDM; two steel pressure test points | Flanged | PN16 or PN25 by order code | -10°C to +120°C |
Brands listed here: Tecofi. CAD sends datasheets, size tables and CO/CQ and advises on valve size from the design flow. Further reading: What is a balancing valve? Construction, types and how to set it.

What does a balancing valve do in an HVAC system?
It gives each branch its design flow, so branches near the pump do not take too much while far ones starve; room temperatures even out and the pump works at its design point.
How is a balancing valve sized?
From the flow and the pressure drop wanted on the branch, not from the pipe diameter. Send the design flow and pipe DN and a CAD engineer will size the valve.
