Overview
The Johnson Controls TBG16A-600R is a steam trap assembly and siphon loop (commonly referred to as a pigtail) designed for use with the Penn/Johnson Controls P47 Series steam pressure controls. It functions as a protective cooling leg, trapping a column of condensate that acts as a thermal barrier to shield internal sensing elements from high-temperature live steam.
Features
- Creates a localized condensate buffer to protect pressure control bellows or diaphragms from thermal shock.
- Delivers a reliable liquid seal to prevent air entry into the system.
- Leverages a compact mechanical design ideal for tight boiler manifolds and industrial piping configurations.
- Provides Universal thread fitting to ensure leak-free connection.
