Features & Benefits
Self-Acting No Power Required
Thermodynamic disc responds to flash steam velocity and pressure -- no electricity, compressed air, or external sensors.
High-Pressure Rating
Robust carbon steel body and hardened disc rated to 800 PSI for superheated steam mains.
Automatic Air Venting
Condensate chamber above the disc accumulates air on start-up and releases it automatically without air binding.
Compact and Lightweight
Small footprint and low weight allow installation in cramped pipe racks and tracing bundles.
Insulation Cap for Outdoor Use
Stainless steel cap prevents wind chill from causing false cycling and steam loss in exposed installations.
