In industrial automation, the precise control of media has a key role. Pressure regulators are indispensable components for maintaining a medium’s pressure at a constant, defined level—independent of fluctuating inlet values or changing flow conditions. At SVS-Automation, pressure regulators are directly integrated into compact valve manifolds and combined with solenoid valves, proportional valves, restrictors, or filters to create intelligent, modular system solutions.
A key advantage of this integration lies in saving space and costs, simplifying installation, and optimizing maintenance. In addition, it allows individual control and regulation requirements to be implemented flexibly—a significant benefit for machine builders and plant operators.
With or without secondary venting? – it depends on the application
Pressure regulators are typically available in two versions: non-relieving (without secondary venting) or relieving (with secondary venting). The correct choice depends largely on the application and the medium. In compressed air systems, a version with secondary venting is often not only unproblematic but even desirable—excess pressure on the secondary side is safely and automatically released. This increases operational safety and ensures stable regulation.
The situation is different, however, with hazardous gases or liquids. For safety and environmental reasons, unintended venting must be strictly avoided. In such cases, a pressure regulator without secondary venting is used. This version completely seals the secondary side and thus prevents any release of the medium.
This design, however, does not come without compromises: pressure regulators without secondary venting generally respond more slowly to pressure changes and may show less dynamic regulation under rapidly changing conditions.
Conclusion
SVS-Automation offers well-thought-out solutions for a wide range of pressure regulation requirements—from compact pneumatic systems to safety-critical media control. Choosing the right type of pressure regulator—whether with or without secondary venting—is crucial for safe, efficient, and reliable operation. Our experts will be glad to assist you in selecting the optimal components for your application.
