ZZY type self-operated control valve
ZZY type self-operated control valve don’t need extra power, but take controlled media energy as power supply。 It brings in actuator to control valve disk position and change two ends differents pressure and flow to make valve upstream and backstream pressure stability. It has agility, good sealing, pressure set point small fluctuations and other advantage and it is used widely in gas, liquid and steam medium to reduce and stable pressure or reliefe pressure self-control.
