  • Introduction
  • Specifications
V230Wself-force temperature -adjusting valve made up of temperature sensor and control valve, need not external energy, just using pressure changes of media itself to automatic adjust pressure, used as pressure-controlling device of non-corrosive liquid、gas and steam. Compare with ZZYP, farer that from spring to valve body, can not affected by media temperature. So widely used in oil、chemical、metallurgy、light industries and cities for heating.
