Quick Pressure Relief Valve IR-73Q
The Model 73Q Quick Pressure Relief Valve is a hydraulically operated, diaphragm actuated control valve that relieves excessive system pressure when this pressure rises above the pre-set value. It immediately, accurately, and with high repeatability responds to system pressure rise by fully opening. The Model 73Q provides smooth drip tight closing.
- Hydraulic actuation
- Independent operation
- Long term drip-tight sealing
- Long term setting stability
- Wide setting range
- Tight setting window
- Minimal hysteresis
- Double chamber design
- Moderated valve closing (no surges)
- Protected diaphragm
- Obstacle free, full bore – Uncompromising reliability
- Balanced seal disk – High relief flow capacity
- Manual test valve – No setting change required
Typical Applications
The Model 73Q Quick Pressure Relief Valve protects against:
- Momentary high pressure peaks Failure of other system components
- Excessive pressure from another source Static condition leaking of pressure reducing valves
