  • Introduction
  • Specifications
ZZC and ZZV Self-force differential(micro)pressure adjusting valve need not external energy. Used for nominal pressure PN01,PN10. differential(micro)pressure can be sub-regulation, from 50mm .W.C to 0.1MPa, used to control two kinds of materials, like gas and air flow ratio to achieve ideal combustion, also used for oil sealing of hydrogen-cooled generator set. If low side of differential valve is passed air, then we call it micro-pressure valve (.
