An unloader valve is a critical pressure control component used in air compressors, pressure washers, and hydraulic systems. It functions by relieving excess pressure when the system reaches its maximum setpoint, preventing damage to the pump and ensuring safe operation.
✔ Pressure Regulation – Maintains optimal system pressure
✔ Pump Protection – Prevents overpressure and motor overload
✔ Energy Efficiency – Reduces power consumption when idling
✔ Durable Construction – Built for high-pressure environments
✔ Easy Adjustment – Field-adjustable pressure settings
Parameter | Description | Typical Values/Specifications |
---|---|---|
Valve Type | Pilot-operated, Pressure-sensitive, Mechanical | Varies by application |
Port Size | Inlet/outlet connection size | 1/4" to 2" (DN8 to DN50) |
Pressure Range | Operating pressure range | 50 to 5000 psi (3.5 to 350 bar) |
Max. Flow Rate | Maximum air/fluid flow capacity | 10 to 300 CFM (280 to 8500 LPM) |
Set Pressure | Adjustable cracking pressure | 50-3000 psi (3.5-210 bar) |
Reset Pressure | Pressure at which valve recloses | Typically 10-20% below set pressure |
Response Time | Time to open/close under pressure change | <100 ms (fast-acting models) |
Body Material | Construction material | Brass, Steel, Stainless Steel |
Seal Material | Sealing components (O-rings, diaphragms) | Nitrile, Viton®, PTFE |
Temperature Range | Operating temperature limits | -30°C to 150°C (-22°F to 302°F) |
Mounting Type | Installation configuration | In-line, Flanged, Threaded |
Certifications | Industry standards | ASME, ISO 9001, CE, PED |
✔ Air Compressors (Reciprocating & rotary screw types)
