- ASME 150Lbs Flange drilling
- KS/JIS 5K Flange drilling
- KS/JIS 10K Flange drilling
Emergency relief equipment used when set pressure is over 700mmH2O.
Designed to adjust set pressure by spring tension. Reseats when the over-pressure has been dissipated.
Drilling conforming to API 650, ASME B 16.5 for class 150 flanges, or KS/JIS 5K/10K flanges Basic material of spring is 304SS of high corrosion resistance so set pressure change is small even in long-term use.
