Gardner Denver Quansi-pneumatic Relief Valve 90AR1082 High Quality Screw Air Compressor Parts Wholesalele

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 Parameters Table

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 (usually below set pressure)	~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, ASME, CE, etc.)	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.
