    Features/Applications

    Features

    • Takes only 1/10th of the previous time required to remove scale

      Disassembly before cleaning is no longer needed. Remove scale instantly by simply turning a handle with no need to stop the flow of steam. The time required is approximately 3 minutes per trap.

    • Reduces scale buildup

      Complete redesign of all internal unit components.
      ・33% increase in bimetal valve stroke volume
      ・Spring opening force 2.2 times stronger
      ・Enlarged valve seat flow channel and space
       *Compared with previous Miyawaki products

    • Pre-emptive action before closing performance deteriorates

      This product enables efficient regular scale removal work. Poor closing performance caused by scale can be prevented through regular scale removal.

    • Superb durability

      SCCV (Self Closing and Centering Valve) System / This is an original mechanism developed by Miyawaki to increase valve durability.
      It has the effect of increasing durability by achieving soft closing.

    Remove scale by simply turning a handle!
    This temperature control trap has a mechanism that allows you to remove scale that has built up in the flow channel (of the valve hole) and discharge it by simply turning a handle at the bottom.

    Discharge Capacity

    ●⊿t is the difference between the temperature of a temperature control trap when the valve is initially opened and condensate temperature.

     The temperature difference (⊿t) upon the initial passage of air is great, and indicates that the flow rate will also increase.

     

    Curve1 shows the trap's maximum capacity when discharaging cold condensate.

    **Curve2 shows the trap's maximum capacity when discharaging hot condensate at a temperature of 10°C (18°F) below the adjusted temperature of the trap.
