Steam trap GTH10 / NEW!

  • SCCV system
  • Suitable for condensate recovery
  • Horizontal installation
  • Automatic venting
  • Option
    • Customized flange
    • Reverse flow direction possible

Properties

  • “Internal counterweight”

    Compact design thanks to “internal counterweight”, a patented technology from MIYAWAKI Inc.
    (Patented no. 7269652)
    This technology eliminates the need for large floats and long levers.

  • Protection against corrosion

    Use of stainless steel components at the corrosion-prone outlet.

  • Venting function

    A manual venting function is provided as standard.
    The air can be released easily during commissioning.

  • Flow in reverse direction

    Reverse flow is optionally available.

  • Particularly dense and durable

    The technology patented by MIYAWAKI, the SCCV mechanism and the separate shaft guarantee a high level of tightness of the steam trap. All valves and valve seats are precision ground.
    (Patented No. 7233721)
    High durability is ensured by stellited valves and valve seats.
