The series of reducers size G1-1/2 and G2 are characterized by a control section and a power section; in fact, the control regulator, located at the top of the body, acts as a pilot element of the main reducer, ensuring limited knob rotation effort and thus better adjustment. Upon request, they are available with a maximum pressure adjustment of 2 and 4 bar and with flow from the right. In cases where the large-sized reducer is installed in hard-to-reach positions, the pilot-operated reducers of the JRP series are available. The adjustment is made by means of a smaller-sized pilot reducer located at a distance from the power one, which can also be chosen in the precision version JRPR. This solution allows for greater sensitivity and precision in the final pressure adjustment.
