Series D - Balanced Pressure Steam Traps
|
|
Balanced Pressure Thermostatic Steam Traps are equipped with a capsule element, which controls the discharge of condensate depending on the temperature. The capsule contains a special liquid, whose saturation temperature at a given pressure is always lower than that of the water. It ensures a very accurate functioning of the steam trap and is self-adjusting.
The discharge characteristic follows the saturation curve independent from pressure changes and the condensate load.
Series D MIYAWAKI steam traps can be delivered with 3 different capsule types:
- Types H & C discharge hot condensate at approximately 5°C (9°F) below saturation temperature
- Type L discharges hot condensate at approximately 15°C (27°F) below saturation temperature

Series S - Thermodynamic Steam Traps
|
Thermodynamic disc steam traps discharge the condensate near the saturation temperature. The traps may operate until a back pressure of 80% of the inlet pressure, but for smooth operation it is recommended that the back pressure does not exceed 50% of the inlet pressure.
Applications:
steam main drips, heat exchangers and all other applications in the petrochemical, food, textile, pharmaceutical and other industries where the condensate must be removed quickly |

Air Traps - Series A
|
MIYAWAKI Air Traps are designed for continuous discharge of condensate from air piping, receiver tanks, gas and compressed air systems.
Depending on the operating conditions and applications a wide range of various types of air traps is available. Most of the traps can be fitted with a pressure - balancing line to ensure air can escape from the trap body to prevent air locking. Pressure-balancing lines are usually not necessary, if the air trap is installed directly below the equipment to be drained or if the trap is installed vertically.
MIYAWAKI offers different seat materials and various body materials (including stainless steel) for draining special gas applications.
MIYAWAKI Air Vents are designed for pipe lines or industrial equipment to remove troublesome air automatically from them. |
