VRV: Vacuum Relief Valves
VRV,s, as per **API 2000**, are designed to protect atmospheric and low-pressure storage tanks from excessive vacuum conditions that could lead to structural damage. These valves ensure proper venting to maintain safe operating pressures.
- **Vacuum Relief Mechanism**: Opens when internal pressure drops below the set limit, preventing tank collapse.
- **Compliance with API 2000**: Meets industry standards for venting storage tanks.
- **Types**:
- **Weight-Operated**: Uses a weighted disc to regulate vacuum relief.
- **Spring-Operated**: Utilizes a calibrated spring for precise control.
- **Pilot-Operated**: Offers enhanced accuracy and stability.
- **Leak-Tight Design**: Ensures minimal product loss and environmental protection- API 2000
- **Sizing Considerations**: Based on tank volume, operating conditions, and required flow rates.
