Compressed air: Your challenges in generating and preparing
Safe and always available compressed air is crucial in addition to the individually required air quality. Given the variety of compressors, you need precisely coordinated valves and advice tailored to your compressed air systems.
Bürkert valve technology for reliable and durable compressed air systems and compressors
We support manufacturers in the design as well as production and users in the long-term operation of compressed air systems. To ensure that the systems run safely, flexibly and economically, you as a manufacturer need the perfect valve for every process step. With a unique range of variable standard valves, individually manufactured valves plus all-round service from Bürkert, your customers always operate quickly and accurately.
1. Valves for intake control
Solenoid valves mainly control the intake control or the inlet valve in screw compressors. The valves are available in various variants, such as de-energised opening and de-energised closing.
These offer the following advantages in application:
✓ Higher energy efficiency
✓ Increased compressor service life
✓ Gentle start-up
✓ Optimised compressor characteristic curve
✓ Lower pressure fluctuation range
✓ Demand-oriented pressure generation
✓ No retroactive pollution in case of emergency stop
Type 7012 Type 0400 Type 5404
2. Valves for intake control - mobile compressors
This is where proportional valves impress at the inlet:
✓ Load and energy consumption are based on the compressed air demand.
✓ Precisely matching of the motor output to the compressed air requirement saves fuel and emissions.
Type 2865 Type 2863 Type 8605
3. Unload valves
To prevent compressors from starting against pressure, a) the pressure relief valve (NC) can vent at stop or b) the unload valve (NO) can relieve the motor at start.
Main advantages of both valve variants:
✓ Lower energy consumption of the compressor
✓ Increased service life of the compressor
Type 5404 Type 6013 Type 6281
4. Valve for condensate drainage
When a compressor compresses air into compressed air, contaminated condensate is usually produced. To avoid damage to the compressed air system, this fluid must be drained and disposed of properly.
Discharge takes place when the compressor is switched on and during set operating intervals. You can connect the drain valve to the condensate treatment unit via a pipeline.
Advantages of automatic condensate drainage:
✓ Prevents damage
✓ Extends service life
✓ Less effort for maintenance and servicing
✓ Saves energy and resources
Type 0330 Type 6430 Type 5282
5. Pressure maintenance valves
A pressure maintenance valve ensures stable pressure in the compressor and in the compressed air preparation unit. It forms the interface between the compressed air system and network and enables a safe start-up. If the network draw-off is low, the pressure-retaining valve protects the compressors and treatment components.
✓ Optimises the use of energy
✓ Uniform network start-up relieves the load on the motor
✓ Increases the life cycle of your system
✓ Ensures permanently consistent compressed air quality
Type 8805 Type 8804 Type 6519
6. Upstream pressure shut-off valves
The inlet valves placed in front of a booster compressor control the air supply during operation and close automatically when the inlet pressure is too low.
The booster compressor draws in pre-compressed and treated compressed air from an existing network or a low-pressure compressor and increases the pressure to a higher level
Type 5404 Type 6519 Type 8805
7. Purge air control valves
Membrane dryers extract moisture from the compressed air produced. They use purge air for this purpose. The pilot valves add the purge air as required and thus ensure energy-efficient operation of the membrane dryer.
Type 6013 Type 7011 Type 0331
8. Change-over valves
A change-over valve allows a crossover and pressure surge-free change-over in adsorption dryers as well as nitrogen and oxygen generators.
In both cases, Bürkert solenoid or process valves specifically switch operation between adsorption and regeneration
Type 2000 Type 7012 Type 6281
