TRV Valve Selection

Step 1: Input the wished flow pressure drop and acceptable tolerance on Kv value

Flow (l/h) =
Dp (kPa) =
Tolerance in the Kv =
Choose the acceptable tolerance in %
between wished and real Kv value
Kv required = m³/h
Dp (kPa) – hydraulic valve resistance.
Flow (l/h) – Сoolant flow through the valve.
Kv – Volumetric water flow in m³/h.

Step 2: List of valves that satisfy your requirements
