Features
- 90° quarter-turn operation to open/close
- Replaceable valve seat with bidirectional sealing performance
- Flow characteristics tend to be linear, providing good adjustment (throttling) performance
- Self-lubricating bearings in PTFE, aluminium-bronze, or stainless steel lined PTFE
- ISO 5211 top flange compatible with manual, electric, and pneumatic actuators
- Multiple shaft-seal design ensures shaft has no contact with service medium (dry shaft)
- Stepped shaft retained by circlip for blow-out proof design
- Pinless two-piece shaft design (one-piece available on request) isolates shaft from medium
- Disc edge machined with spherical surface and polished to reduce operating torque
- Streamlined disc profile minimises pressure drop
- Valve seat and body positioned with single or double grooves to prevent displacement during operation
- Valve seat outer surface has circular arc profile for accurate positioning and easy replacement
