Welded Metal Hard Seal Butterfly Valve
Product overview
Welded metal hard seal butterfly valve uses three eccentric structure, this valve design applied in high temperature and high pressure, fire prevention is an ideal hard seal butterfly valve to a level bubble. Due to the welding structure, so the valve and pipeline plane to achieve permanent zero leakage, should not have a flange welding butterfly valve, pipe insulation bandaging has brought great convenience.
