Kaeser Pneumatic Operated Valve Replacement – 7.4801E3

he Kaeser 7.4801E3 Pneumatic Operated Valve is a genuine OEM control valve used in Kaeser rotary screw air compressors. It is responsible for pneumatically actuating the compressor’s air control system, enabling smooth loading and unloading of the compressor based on air demand. The valve plays a critical role in maintaining stable compressor operation, improving energy efficiency, and protecting internal components from unnecessary wear.

Key Features

• Genuine Kaeser OEM pneumatic operated valve
• Precise pneumatic actuation for compressor control
• Fast response during load/unload cycles
• Durable industrial-grade construction
• High reliability under continuous operation
• Direct replacement for part numbers 7.4801E3, 74801E3, and 7.4801.E3.

Benefits

• Optimizes compressor loading and unloading
• Improves energy efficiency
• Ensures stable compressed air delivery
• Reduces wear on the air end and control components
• Minimizes downtime and maintenance costs
• Extends compressor service life.

Working Process

1. The compressor controller sends a pneumatic control signal.
2. The 7.4801E3 pneumatic valve actuates the inlet/control mechanism.
3. During high air demand, the valve opens to allow the compressor to load and compress air.
4. When demand decreases or the pressure setpoint is reached, the valve unloads the compressor, reducing power consumption.
5. The valve continuously responds to pressure changes to maintain efficient compressor operation.

Typical Applications

• Kaeser rotary screw air compressors
• Industrial manufacturing facilities
• Automotive workshops
• Engineering and fabrication plants
• Continuous-duty compressed air systems.
