Steam trap TBH81

  • SCCV system
  • Suitable for condensate recovery
  • Horizontal installation
  • Vertical installation

  • Completely closed

    The temperature control trap enables adjustable subcooling of the condensate. This maintains a specific condensate level in the trap. The mechanism is 100% leak-proof, which effectively prevents steam loss during operation.

  • Suitable for high pressures, high temperatures and superheated steam

  • Outstanding durability

    The MIYAWAKI SCCV system (Self Closing and Centering Valve) is characterized by a significantly longer service life thanks to the reduced closing forces.
    The freely rotating valve always sits optimally in the valve guide, even under the extreme conditions that prevail in high-pressure applications, as it is centered and guided by the condensate flow. This design significantly reduces stress and therefore wear on the valve components.

  • Fast commissioning

    Discharges the cold condensate and cold air quickly.

  • Energy savings

    Controlling the temperature of the discharged condensate ensures significant energy savings.

  • Low operating noise and very low formation of flash steam

Typical applications

Suitable for steam main lines, steam tracing and other similar applications.

● Max. permissible pressure (PMA): 250 bar (at 492 ℃)
● Max. permissible temperature (TMA): 593 ℃ (at 37 bar)
● Min. operating differential pressure (⊿PMN): 10 bar ⊿PMN is the minimum operating differential pressure between the inlet and outlet of the condensate drain.

● If there are no special instructions for the set temperature, the product is set to the above factory default setting for shipping.
The set temperature must be at least 30 ℃ lower than the saturation temperature for the vapor pressure used.
* The TBH72 housing can also be manufactured from a forged chrome-molybdenum steel alloy (A182 F22 and A182 F91).

● ⊿t is the difference between the temperature of a temperature control trap when the valve is first opened and the temperature of the condensate. The temperature difference (⊿t) at the first flow of air is large and indicates that the flow rate will also increase.
