Applications

Clean steam and high purity water applications such as sterilizers, fermentation tanks, food processing, etc.

Operating principle

A welded stainless steel bellows senses the trap inlet pressure and temperature and controls the condensate discharge, following the saturating steam curve closely within 10 °F.
