Central components for pressure control<\/h2><\/div>

Valves in the compressed air system regulate, direct and limit the air flow in a variety of ways – e.g. brake valves for trailers, operating or locking functions. They ensure that compressed air is used in a targeted manner, control functions are supported and safety systems work reliably.<\/p>\n<\/div>

Precision in pressure setting & function<\/h2><\/div>

A well-designed valve must deliver the correct operating pressure and switch reliably between switching states. Only if the connections, pressure setting and sealing surfaces match each other exactly can proper functioning without leakage losses or dead zones be guaranteed.<\/p>\n<\/div><\/div><\/div>

The heart of truck braking and control systems<\/strong>
In trucks, valves are the absolute neural center of the compressed air system. They not only control the essential braking function (service, parking and emergency brake), but also all other pneumatically operated systems, such as the air suspension, transmission shifting (in automated manual transmissions) and auxiliary consumers. The complexity of these valves is immense: from simple non-return valves to multi-circuit protection valves and electronically controlled solenoid valves – they all have to precisely regulate pressures of up to 12 bar and switch quickly in order to guarantee the safety and functionality of the entire vehicle. <\/p>\n<\/div><\/div><\/div>

Functional safety and electronic control<\/strong>
\nThe highest requirement for valves in trucks is functional safety within the dual-circuit brake system. Special pressure control and overflow valves ensure that the other circuit remains functional in the event of a pressure loss in one circuit. Modern commercial vehicles are also increasingly using electronically controlled valves (e.g. in the EBS\/ABS system). These valves must react at lightning speed to signals from the control unit in order to optimally modulate the brake pressure at each individual wheel. The precision of the pressure control provided by these valves is directly decisive for the stability of the truck, the shortening of the braking distance and the prevention of locking or skidding.<\/p>\n<\/div><\/div><\/div>

Robustness, tightness and durability<\/strong>
\nIn view of the constant vibrations, extreme temperature differences and potential contamination of the compressed air by oil residue from the compressor, valves for trucks must be made of extremely resistant materials. Sealing technology is particularly critical here: the slightest leaks lead to unnecessary refilling by the air compressor and increase wear in the entire compressed air system. When replacing brake and control valves, uncompromising attention must therefore be paid to maintaining original equipment quality (OE quality) in order to ensure full pneumatic performance and compliance with the long maintenance intervals in continuous commercial use.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

Expert Guide: Everything You Need to Know About Compressed Air System Valves<\/h2><\/div>\n
\n

<\/i><\/i><\/span>What is the function of valves in a compressed air system?<\/span><\/a><\/h4><\/div>
Valves regulate, direct, and restrict the flow of air in the compressed-air system. They control the essential braking functions (service, parking, and emergency brakes) as well as other pneumatic systems such as air suspension and transmission shifting. This makes them a key control element for the vehicle\u2019s safety and operation.<\/div><\/div><\/div>\n

<\/i><\/i><\/span>What types of valves are used in a compressed air system?<\/span><\/a><\/h4><\/div>
The product range extends from simple check valves to pressure-regulating and relief valves, as well as multi-circuit safety valves and electronically controlled solenoid valves. They all precisely regulate pressures of up to approximately 12 bar and switch quickly between operating states.<\/div><\/div><\/div>\n

<\/i><\/i><\/span>What role do valves play in the safety of a dual-circuit braking system?<\/span><\/a><\/h4><\/div>
Special pressure-regulating and relief valves ensure that if pressure is lost in one brake circuit, the other circuit remains operational. In modern EBS\/ABS systems, electronically controlled valves modulate the brake pressure at each wheel in a flash\u2014which is crucial for stability, short stopping distances, and preventing wheel lockup.<\/div><\/div><\/div>\n

<\/i><\/i><\/span>How can you tell if a valve is defective?<\/span><\/a><\/h4><\/div>
Typical signs include audible air leaks, slow pressure buildup, failure to reach the target pressure, brakes that are slow to release or fail to release, and error codes stored in electronic valves. Since valves are critical to safety, such symptoms should be checked immediately.<\/div><\/div><\/div>\n

<\/i><\/i><\/span>Why is valve tightness so important?<\/span><\/a><\/h4><\/div>
Even the slightest leaks cause the compressor to have to make up for the loss unnecessarily, which increases wear throughout the entire compressed air system. Since valves are also exposed to constant vibrations, temperature fluctuations, and oil-contaminated air, they must be made of durable materials and be reliably sealed.<\/div><\/div><\/div>\n

<\/i><\/i><\/span>What should you look for when buying a valve?<\/span><\/a><\/h4><\/div>
The valve must be suitable for the intended pressure range and the desired function (e.g., pilot-operated, brake, or relief valve). Make sure that the connections, threads, and number of connections match your system and that the valve features a robust sealing system capable of withstanding the environmental conditions.<\/div><\/div><\/div>\n
