It responds immediately and with high repeatability by opening fully and provides smooth, drip-tight closing.
Hydraulic Pressure Control
- Line-pressure driven for autonomous operation
- Long-term drip-tight sealing
- Stable setting over time
- Wide setting range to suit system requirements
- Tight setting window with minimal hysteresis
Advanced Hydro-Efficient Globe Design
- Unobstructed flow path reduces turbulence and pressure loss
- Single moving part simplifies maintenance
- High flow capacity for rapid pressure relief
Fully Supported & Balanced Diaphragm
- Requires low opening and actuation pressure
- Progressively restrains valve closing for controlled shut-off
- Prevents diaphragm distortion to ensure longevity
User-Friendly Design
- Easy pressure setting for fast commissioning
- Simple in-line inspection and service to reduce downtime
Typical Applications
- System burst protection
- Momentary pressure peak elimination
- System failure visual indication
- Filter burst protection
Additional Features
- F : Large control filter
- I : Position indicator assembly
