Gardner Denver Quansi-pneumatic Relief Valve 90AR1082
High Quality Screw Air Compressor Parts
Pneumatic Relief Valve Product Overview
A pneumatic relief valve is a safety device designed to protect pneumatic systems from overpressure by automatically releasing excess air when the pressure exceeds a predefined set point. These valves are essential in maintaining system integrity, preventing equipment damage, and ensuring operational safety.
Key Features
- Pressure Regulation: Maintains system pressure within safe limits
- Automatic Operation: Opens when pressure exceeds the set limit and reseals when normal pressure is restored
- Material Options: Available in brass, stainless steel, or aluminum for different applications
- Adjustable or Fixed Set Pressure: Some models allow for manual adjustment
- Quick Response Time: Ensures rapid pressure relief to prevent system failure
Typical Applications
- Compressed air systems
- Pneumatic cylinders & actuators
- Air tanks & receivers
- Industrial machinery
- HVAC systems
- Process control systems
Pneumatic Relief Valve Technical Specifications
| Parameter | Description | Typical Values |
|---|---|---|
| Set Pressure Range | Operating pressure range at which the valve opens | 0.5 - 20 bar (7 - 290 psi) |
| Connection Type | Thread size & standard (e.g., NPT, BSP, G) | 1/8", 1/4", 3/8", 1/2" NPT/BSP |
| Flow Capacity (Cv) | Flow coefficient indicating valve efficiency | 0.1 - 5.0 Cv |
| Material | Body & seal material | Brass, Stainless Steel, Aluminum, PTFE |
| Temperature Range | Operating temperature limits | -20°C to +120°C (-4°F to +248°F) |
| Reset Pressure | Pressure at which the valve recloses | ~90% of set pressure |
| Leakage Rate | Maximum allowable leakage when closed | < 0.1% of rated flow |
| Response Time | Time taken to open fully once pressure exceeds set point | < 50 ms |
| Weight | Approximate valve weight | 0.1 - 2 kg (0.22 - 4.4 lbs) |
| Certifications | Compliance with industry standards | ISO 4126, ASME, CE, PED |
Selection Considerations
- System Pressure: Choose a valve with a set pressure slightly above normal operating pressure
- Flow Requirements: Ensure the Cv rating matches system airflow needs
- Environmental Conditions: Consider temperature, humidity, and potential corrosive elements
- Maintenance: Some valves require periodic testing to ensure proper function
