Reverse Type
KSRR
Design
- Reverse Dome Knife Type
- It is used with installation on FDC standard holder
- Reversal structure ruptured by knife blade attached upper holder while dome is inverted
Product Features
- Highly safe and resistant to corrosion
- Favourable for counterpressure, vacuum and pulsation conditions
- Vacuum Support is needless
- Wide range of workable temperature
- Long life of disc as there is small gap between working pressure and rupture pressure
