Gardner Denver Solenoid Valve QX114716 for Air Compressor 24V DC
A Solenoid Valve is an electromechanically operated valve that uses an electric current to control the flow of liquids or gases. It consists of a solenoid (an electromagnetic coil) and a valve body. When energized, the solenoid creates a magnetic field that actuates a plunger or piston, opening or closing the valve orifice. This provides remote, fast, and reliable on/off or directional control of fluids in a wide range of industrial and commercial applications.
The core function of a solenoid valve is to automate fluid control. Its specific purposes include:
- Remote Operation: Allows valves to be controlled from a distance via electrical signals, enabling automation.
- Fast Response: Opens or closes rapidly (milliseconds to seconds), ideal for precise timing and sequencing.
- Emergency Shut-Off: Can be integrated with safety systems to automatically stop flow in critical situations.
- Directional Control: Direct-acting and pilot-operated models can divert, release, or mix fluids in complex systems.
- Energy Efficiency: Consumes power only during state change (open/close), not while holding position.
Solenoid valves operate based on electromagnetic principles:
- De-Energized State: A spring or fluid pressure holds the valve in its default position.
- Energized State: When current flows through the coil, it generates a magnetic field.
- Actuation: The magnetic field pulls a ferromagnetic plunger upward against the spring force.
- Orifice Control: The plunger's movement opens or closes the orifice, allowing or blocking flow.
- De-Energization: When current stops, the spring returns the plunger to its default position.
Pilot-operated solenoid valves use line pressure to assist in opening/closing the main orifice, enabling control of higher pressures with a smaller coil.
| Feature | Benefit |
|---|---|
| Compact Design | Saves space in control panels and machinery. |
| Rapid Cycling | Handles frequent on/off operations without wear. |
| Low Power Consumption | Energy-efficient, especially in latching designs. |
| Versatile Configurations | Available in 2-way, 3-way, 4-way designs. |
| Broad Compatibility | Suitable for water, air, oil, steam, and chemicals. |
| Easy Integration | Standard electrical connections and port sizes. |
| Type | Description | Primary Application |
|---|---|---|
| Direct-Acting | Solenoid force directly opens/closes the orifice. Works from 0 pressure. | Low flow rates, low-pressure applications. |
| Pilot-Operated | Uses line pressure to assist operation. Requires minimum pressure differential. | High flow rates, higher pressure systems. |
| 2-Way | Two ports (inlet/outlet); basic on/off control. | Simple shut-off applications. |
| 3-Way | Three ports; alternates flow between two paths. | Controlling single-acting actuators, diverting flow. |
| 4-Way | Four ports; controls double-acting actuators. | Pneumatic cylinders, reversing actuators. |
Solenoid valves are ubiquitous across industries:
- Industrial Automation: Controlling air, water, and oil in machinery.
- HVAC: Refrigerant control, zoning valves, compressor sequencing.
- Water Treatment: Filter backwashing, chemical dosing, irrigation.
- Medical & Dental: Equipment wash-down, gas control, analyzers.
- Automotive: Fuel injection, transmission control, air suspension.
- Reliability: Precision-engineered for millions of cycles.

- Energy-Efficient Designs: Low power consumption options.
- Global Certifications: CE, UL, CSA, ATEX compliant.
- Technical Support: Expert assistance with sizing and selection.
To select the correct solenoid valve, specify:
- Function: 2/3/4-way, NC/NO
- Media: Fluid type, viscosity, temperature
- Pressure: Min/Max operating and differential pressure
- Flow Rate: Required Cv or flow volume
- Voltage: AC/DC and frequency
