Drain valve

Steam trap, also known as automatic drainer or condensate drainer, is installed at the end of steam‑heated pipelines. It continuously discharges condensate generated inside steam heating pipelines while preventing steam from escaping out of the system. Most steam traps can automatically distinguish steam from condensate (except thermostatic static type), realizing automatic steam‑blocking and condensate‑draining performance. Widely adopted in petrochemical, food & pharmaceutical, power plant and other industries, it plays an important role in energy conservation and emission reduction.
