The Atlas Copco 1622379881 Electronic Drain Valve is a high-precision condensate management device designed for environments where moisture accumulation must be controlled with strict timing and stable repeatability. Unlike mechanical or pressure-sensing drains, this model uses an electronic timer and solenoid actuation to ensure predictable discharge cycles regardless of fluctuating compressor load, humidity level, or tank pressure.
This valve is ideal for facilities that require uninterrupted drainage during 24-hour operations, as its programmable timing logic allows technicians to tune discharge intervals and duration exactly to system conditions. Its reinforced housing, wide-bore discharge path, and contamination-resistant internal solenoid make it especially suitable for screw compressors operating with heavy condensate loads or oil-rich mixtures.
Key Features
1. Solenoid-Driven Precision Control
The 1622379881 uses a durable industrial solenoid coil to open the valve at predefined intervals. This eliminates the uncertainty of mechanical actuation and ensures that condensate is discharged consistently, even during low-pressure or intermittent load conditions.
The solenoid assembly is built for long cycle life, offering stable magnetic force and reduced heat buildup during continuous operation.
2. Programmable Electronic Timer Module
A dedicated control module allows technicians to adjust:
- Drain interval (time between openings)
- Drain duration (how long the valve stays open)
This flexibility ensures proper drainage across different operating environments—whether the system produces large volumes of condensate during high-humidity seasons or minimal moisture during lighter duties.
3. Anti-Blockage, Large-Flow Discharge Path
Internally, the valve incorporates a wide flow channel and corrosion-resistant materials designed to handle:
- Oil-contaminated water
- Dense emulsified condensate
- Rust particles
- Small solid contaminants
This significantly reduces clogging frequency and ensures stable, unrestricted discharge throughout long service periods.
4. Heavy-Duty Housing for Industrial Reliability
The valve body is constructed from high-strength corrosion-resistant alloy, maintaining structural stability under heat, pressure pulses, and chemical exposure.
The electronic components are protected within a sealed enclosure that shields them from moisture, oil mist, and vibration—common conditions around screw compressor bases.
5. Energy-Efficient & Safe Electrical Operation
The solenoid coil is designed with low energy consumption and includes overheat protection to ensure continuous, safe operation.
The wiring block supports secure installation, with insulated terminals that protect against short circuits and electrical noise from high-power compressor motors.
Working Principle
- Timer counts down based on the programmed interval.
- At the preset moment, the solenoid energizes, pulling the plunger and opening the valve.
- Condensate flows out rapidly through the enlarged port.
- When the programmed duration is complete, the timer shuts off the coil, and the valve closes.
This method ensures that condensate is removed proactively rather than reactively, preventing moisture buildup regardless of pressure fluctuations inside the separator or tank.
Performance Benefits
- Stable Drainage in All Operating Conditions
Electronic control prevents failures associated with low pressure, inconsistent load cycles, or slow accumulation stages. - Improved Air Quality & System Cleanliness
Timely condensate removal keeps downstream dryers, filters, and pipelines free of water, reducing corrosion and oil-water emulsification. - Reduced Maintenance and Downtime
The wide discharge channel and solenoid design minimize clogging, decreasing manual cleaning frequency. - Higher Efficiency for Screw Compressors
By keeping the separator tank dry, the compressor maintains more efficient separation, reduces oil carryover, and stabilizes discharge pressure.
Quality Assurance & Testing
Each Electronic Drain Valve 1622379881 undergoes strict inspection procedures:
- Functional timer test
- Solenoid cycle endurance test
- Flow rate verification under contaminated condensate
- Electrical insulation and overload testing
- Leak-tightness confirmation at various pressures
Only components that meet OEM-level performance standards are released.
