Ingersoll-Rand 22124085 Solenoid Valve for Air Compressors

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:

1. De-energized State: A spring or fluid pressure holds the valve in its default position.
2. Energized State: When current flows through the coil, it generates a magnetic field.
3. Actuation: The magnetic field pulls a ferromagnetic plunger upward against the spring force.
4. Orifice Control: The plunger's movement opens or closes the orifice, allowing or blocking flow.
5. De-energization: When current stops, the magnetic field collapses, and 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.

• Orifice Size: Ranges from capillary-sized to several inches.
• Pressure Range: From vacuum to 1000+ PSI, depending on type and design.
• Voltage Options: AC (24V, 120V, 240V) or DC (12V, 24V) coil voltages.
• Flow Coefficient (Cv): Indicates flow capacity; critical for sizing.
• Response Time: Typically 10-1000 milliseconds.
• Port Connections: NPT, BSPP, flange, or manifold mounting.
• Media Temperature: From cryogenic to 200°C+, based on seal materials.

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, ensuring long service life.
• Broad Product Range: Thousands of standard and custom models for every application.
• Energy-Efficient Designs: Low power consumption and latching options reduce operating costs.
• Global Certifications: CE, UL, CSA, ATEX, and more for worldwide compliance.
• Technical Support: Expert assistance with sizing, material selection, and system integration.

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.
