Product Description
Atmospheric Valve Product Introduction
Overview
An Atmospheric Valve (also called a breather valve or vacuum relief valve) is a safety device designed to regulate pressure in storage tanks by allowing air inflow/outflow to maintain equilibrium with atmospheric pressure. It prevents tank damage from overpressure (during filling) or vacuum (during emptying).
Key Features & Benefits
- Dual-Action Protection - Combines pressure relief + vacuum relief in one unit
- Prevents Tank Collapse/Explosion - Maintains safe ±0.2-1.0 PSI range
- Weather-Resistant - Stainless steel or aluminum construction with rain hood
- Fire-Safe Design - Fusible ring melts to allow emergency venting (API 2000 compliant)
- Low Maintenance - No moving parts, self-cleaning mesh filter
Types & Configurations
| Type | Function | Applications |
|---|---|---|
| Pressure/Vacuum (P/V) Valve | Balanced breather for bidirectional flow | Fuel tanks, chemical storage |
| Vacuum Breaker | Prevents tank implosion only | Dairy tanks, pharmaceutical vessels |
| Emergency Vent | High-capacity pressure release | Crude oil tanks, LNG storage |
| Flame Arrester Valve | Stops flame propagation | Hazardous material tanks (ATEX Zone 1) |
Technical Specifications
- Set Pressure Range: 0.1-5 PSI (adjustable)
- Connection Size: 1" to 8" NPT/Flange (ANSI/DIN standards)
- Temperature Range: -40°C to +200°C (high-temp models available)
- Flow Capacity: 10-10,000 m³/h (depends on valve size)
- Certifications: API 2000, ISO 28300, ATEX, PED
Applications
- Oil & Gas: Crude oil storage tanks, LNG terminals
- Chemical Industry: Solvent/acid storage vessels
- Food/Beverage: Edible oil tanks, fermentation containers
- Agriculture: Grain silos, fertilizer storage
- Water Treatment: Sealed wastewater tanks
Working Principle
- Overpressure Scenario:
- Tank pressure exceeds setpoint → Valve opens to release air/gas
- Vacuum Scenario:
- Tank pressure drops below atmospheric → Valve admits ambient air
- Normal Conditions:
- Valve remains closed to prevent vapor loss/contamination
Selection Guide
- Tank Type: Fixed roof (needs P/V valve) vs. floating roof (needs vacuum breaker)
- Fluid Properties: Corrosive? Flammable? (Material compatibility check required)
- Flow Demand: Calculate required venting capacity based on tank filling/emptying rate
- Regulations: API 2000 for oil tanks, FDA standards for food-grade applications
Installation & Maintenance
Critical Notes:
- Install on tank roof/non-flooded vent lines
- Orient rain hood downward to prevent water ingress
- Inspect every 6 months for clogging (clean mesh filter if needed)
- Replace fusible elements after fire incidents
