CHTB17 series regulator is suitable for building regulator box, regional regulator cabinet, industrial and commercial users. Its built-in balance compensation system enables the regulator to provide stable outlet pressure even under working conditions with large changes in inlet pressure. Modular design, more convenient online maintenance.
