CHT series regulator is a two-stage decompression structure. With a unique level of pre-decompression and pressure stabilization, along with built-in dissipation and overpressure cut-off function, to ensure that the series regulator in use with better stability and higher security. Suitable for building regulators or small commercial users, etc.
