    What is Radiator Trap?

    It is a trap mainly installed at condensate outlet side of radiator for steam heater.

    Thermostatic type, such as bellows type or wax type, is used.

    Because heat sensitive area sensing temperature is larger than wax type, and responsiveness of temperature

    change is good, condensate retention is quite small and condensate is discharged quickly.

    Bellows type

    Because sensor which senses temperature is capsule wax type, its structure is effective for impact pressure

    of water hammer, etc.

    It is used with installed on heat release equipment using cold and hot water mainly. By regulating valve

    opening constant, it can be used as return valve.

    It is used with installed on heat release equipment of heater, which uses steam mainly. Flow rate can be

    regulated manually.

    TS-3A

    TS-3S

    The TS-3 radiator trap, like the TS-1, is bellows

    thermostatic type and supports a working pressure of up to

    0.2 MPa. It is used for a wide variety of radiators for

    heating.

    1. Compact, lightweight and reduced noise.

    2. Prevents freezing damage since designed not to allow

    condensate to remain inside.

    3. Quickly discharges cold condensate and air at the start of

    operation.

    4. The valve and valve seat are made of stainless steel.

    Fluororesin is used for the cover gasket, making disassembly

    and assembly easy.
