A bucket-type steam trap made by FCD that supports high pressure and is used for draining high-pressure steam lines, headers, equipment, etc.
A large amount of drain can be discharged compared to the conventional high-pressure bucket type.
Where to use
High pressure steam lineheadermachine

Major features

  • The SSR-Shockless Self Return-mechanism is adopted. It reduces the impact when the valve is closed, and the valve body self-closes regardless of the buoyancy of the bucket, so it can be used from low pressure to high pressure.
  • By adopting a protector with a new structure on the valve seat outlet side, wear resistance and corrosion resistance have been improved even at high pressure, and a longer life has been achieved.

Frequently Asked Questions and Explanations

What is a drain?

In steam-related terms, it refers to steam condensed water (a state in which steam has cooled and returned to water).

What is the role of the steam trap?

When the steam cools, it returns to water (drain). If drainage accumulates in the piping and equipment, it may reduce the efficiency of the equipment and cause water hammer, so it is used for the purpose of automatically discharging the generated drainage.

What is the role of the bypass circuit in the steam trap with bypass?

The bypass function is used at the initial stage of ventilation of equipment, etc., and it is used for the purpose of discharging a large amount of air and drain to accelerate the start-up time.
