  • KVC Hot Gas Bypass Regulator Valves Technical Data

    KVC is a hot gas bypass regulator for the adaption of the compressor capacity to the actual evaporator load.

    Placed in a bypass between high and low pressure sides of the refrigeration system, KVC imposes a lower limit on the compressor suction pressure by supplying the low pressure side with replacement capacity in the form of hot gas / cool gas from the high pressure side.


    • Accurate, adjustable pressure regulation
    • Wide capacity and operating ranges
    • Pulsation damping design
    • Stainless steel bellows
    • Compact angle design for easy installation
    • “Hermetic” brazed construction
    • Available with flare and ODF solder connections
    • May be used in the following EX range: Category 3 (Zone 2

    RefrigerantsR22, R1270, R134a, R290, R404A, R407A, R407C, R407F, R448A, R449A, R450A, R452A, R507A, R513A, R600, R600a
    Regulating range0.2 – 6 bar (2.9 – 87 psig)
    Factory setting = 2 bar (29 psig)
    Maximum working pressurePS/MWP PS = 28 bar (406 psig)
    Maximum test pressurePe = 31 bar (449 psig)
    Medium temperature range-45 – 130 °C
    Maximum P-band2.0 bar (29 psig)
    Kv-value 1) with maximum P-bandKVC 12 = 0.68 m3 / h
    KVC 15 = 1.25 m3 / h
    KVC 20 = 1.85 m3 / h

    1) The Kv value is the flow of water in [m3 / h] at a pressure drop across valve of 1 bar, ρ = 1000 kg / m3.

    This product is evaluated for R290, R600, R600a, R1270 by ignition source assessment in accordance with standard EN13463-1.

    034L0147KVC155/8 Solder14.99.413.616.4

    1) Rated capacity is the regulator capacity at
    evaporating temperature te = -10 °C
    condensing temperature tc = +25°C
    offset = 0.7 bar (10.1 psig)

    The connection dimensions chosen must not be too small, as gas velocities in excess of 40 m / s at the inlet of the regulator can result in flow noise.

    If the discharge tube temperature becomes too high in relation to the compressor specification, the installation of an injection valve in a bypass between liquid line and compressor suction line is recommended.
