    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

    Valve shape DN P/N Presetting Kv
    Angle 10
    Straight 10
    Angle 15
    Straight 15
    Angle 20
    Straight 20
    – Angle
    – Straight
    – Presetting

    Step 3: Flow/Dp calculation

    Dp (kPa) =
    Valve shape DN P/N Presetting Kv Flow (l/h)
    Angle 10
    Straight 10
    Angle 15
    Straight 15
    Angle 20
    Straight 20
    Flow (l/h) =
    Valve shape DN P/N Presetting Kv Dp (kPa)
    Angle 10
    Straight 10
    Angle 15
    Straight 15
    Angle 20
