In many industrial and medical applications, one aspect is key: precise pressure control. Whether it's air, CO₂, or liquids, a fluctuating inlet pressure must be reliably brought down to a stable output level. This is where mechanical diaphragm pressure regulators prove their value, with excellent control accuracy, robust design, and compatibility across multiple media. These regulators operate entirely mechanically, based on the principle of force equilibrium between medium pressure and spring force. This allows them to regulate pressure without any external power supply and to maintain it reliably. The result: accurate, passive regulation without electronics, ideal for many stationary and mobile applications in industrial and medical device technology.

Compact, modular, and versatile

Today’s pressure regulators must do more than just reduce pressure. They must be compact, durable, cost-efficient, and easy to integrate. Oursolutionsoffer:

Expert Florian Falk explains: “In sensitive applications such as analytical or medical technology, precise regulation with high repeatability is critical. That’s where our diaphragm pressure regulators really stand out.”

Finding the right pressure regulator: What matters in the selection process?

The path to optimal pressure control starts with an individual application analysis:

• Which medium is to be regulated (e.g., dry air, oxygen, liquid)?

• What pressure ranges are required (inlet and outlet)?

• What is the expected flow rate?

• What environmental conditions apply (temperature, hygiene, installation position)?

Based on these parameters, we use simulation data and real-world testing to determine the best technical and economic fit from our product range. In particularly sensitive applications, such as ventilation systems, we support our customers with in-depth standards knowledge and extensive experience regarding requirements such as biocompatibility.

NEW: Our Pure Flow Pressure Regulator 48.3

A highlight of our current portfolio is the new Pure Flow Pressure Regulator 48.3 – developed specifically to meet the demanding requirements of medical technology.
It is ideally suited for the precise control of medical gases in devices such as:

• Ventilators and anesthesia equipment
