Double Acting Type
KSROD
Design
- Composite Flat Double Acting Type for Flange
- Used with installation on Flange without holder
- Composite/Flat structure ruptured by slit processed on Top disc
- It consists of Top disc, Seal disc and Vacuum disc
Product Features
- Can set different rupture pressure for two directions
- It is applied to low pressure mainly
- Resistant to corrosion according to Seal Disc materials
- Precise rupture performance and excellent reliability
- Vulnerability to pulsation conditions
- If Teflon in used as Seal Disc material, it is weak to high temperature
- Limited temperature range by Seal Disc material
Connection
KSROHD
- Composite Flat Double Acting Type
- Same as KSROD, but it is used with installation on FDC standard holder
KSROFD
- Composite Flat Double Acting Type for Ferrule
- Same as KSROD, but used with installation on Ferrule Connection without holder
