What is the Emergency Pressure Relief Valve?

In industries like petrochemicals and pharmaceuticals, when standard safety measures fail, the emergency relief valve acts as the "last line of defense" for tank safety. As a leading safety equipment manufacturer in China, we at Basco developed the Model 7100 Overpressure Emergency Relief Valve—a critical safeguard for extreme conditions.

Model 7100: The Ultimate Safety Guardian

Key Advantages

Ultra-Low Leakage & High Precision

50% tighter leakage than API 2000 standards

±3% set pressure accuracy (industry average: ±5%)

Full-Lift Design

100% opening at overpressure, with 40% faster venting

Corrosion Resistance

316L stainless steel body, resistant to acids/alkalis

Certified for harsh environments (NACE MR0175)

Easy Maintenance

All components field-replaceable—repairs in 30 minutes

Technical Breakthroughs

Certified flow capacity: Third-party tested for rapid fire scenario venting

Smart hinge mechanism: Precise resealing, even after repeated cycles

Multi-standard flanges: ANSI, DIN, HG/T compatible—globally adaptable

 When is an Emergency Relief Valve Needed?

When standard valves fail due to:
✔ Fire emergencies (sudden pressure spikes from heat)
✔ Runaway reactions (e.g., uncontrolled polymerization)
✔ Mechanical failures (stuck primary valves)

The Model 7100 responds by:

Instant release: Hinged lid pops open at set pressure

Auto-resealing: Returns to airtight closure post-event

Why is water coming out of emergency relief valve?Professional Answers from Basco

If you notice water leaking from your emergency relief valve, it's typically due to one of these three reasons:
Pressure abnormality: Sudden system pressure spikes (e.g., pump failure or water hammer)
 Valve aging: Worn seals or failed springs
Water quality issues: Scaling/corrosion causing valve jamming

Our Solutions:
Waterproof emergency relief valve: Specially designed for water systems, rust and scale-resistant
 Smart monitoring version: With pressure alarm for early detection
Quick maintenance: All parts field-replaceable

what is the 3 rule for emergency relief valves ?
Basco Safety Expert Recommendations

Regular Check-ups
Inspect at least once a year—just like a "health check-up" for your equipment.

Proper Selection
Choose based on medium characteristics:

Water systems → Choose Basco waterproof & scale-resistant type

Chemical media → Choose corrosion-resistant type

High-temperature conditions → Choose heat-resistant reinforced type

Timely Replacement
Replace immediately if:
✔ Fails to reset after pressure relief
✔ Severe valve body corrosion
✔ No response when pressure exceeds limit
