Valves Chemical engineering – For demanding processes

Challenges in valve technology for the chemical industry

In the chemical industry, compromise is not an option. Anyone who works with aggressive liquids, gases, or highly reactive substances knows the challenge. Valves must withstand extreme pressure and temperature loads as well as chemical corrosion and mechanical stress—and do so continuously. At the same time, the demands on efficiency, traceability, cleaning, and digitalization are increasing.
Typical problems before placing an order:

Uncertainty regarding media compatibility (acids, alkalis, gases)
Failure risks at high temperatures or pressure peaks
Lack of flexibility in standard solutions
High maintenance costs due to material fatigue
Time and cost pressures during renovation or new projects

In short: standard solutions are often not enough. Special solutions are needed—and quickly.

Valve technology for the chemical industry that fits

At RSG, we know what matters. Our valves for chemical engineering are designed to meet the toughest requirements—not at a desk, but in collaboration with customers in the industry. Whether for dosing processes, media control, or safety applications, we configure valves exactly to your specifications. Quickly, transparently, and with maximum material resistance.

Thanks to our modular system, we deliver solutions that are not only technically perfect, but also economically viable. Plastic valves with separating diaphragms? Coaxial valves for highly reactive gases? Control valves with stepless control? We do it all. Always with a focus on service life, cleanability, and process reliability.

Advantages of our valves in chemical engineering

Wide range of materials for aggressive media: PTFE , PVDF, stainless steel 1.4571 – individually configurable depending on the medium
Pressure and temperature resistant: up to 450 bar and over 130°C – no problem
Smooth inner surfaces & media separation: idealfor cleanability and media changes
CIP/SIP-compatible: Cleaning processes can be easily integrated
Modular & flexible: Customization down to the smallest detail thanks to our modular system
Durable & low maintenance: Minimal downtime, maximum service life
"Made in Germany": Development , production, and testing from a single source

Application examples for valve technology in the chemical industry

Aromatic production:
Coaxial valves with PTFE seals and stainless steel housings in a plant for the production of volatile aromatic substances.
Cleaning of reaction vessels:
Motor-driven control valves for precise dosing of cleaning chemicals under changing pressure conditions.
Gas metering in synthesis plants:
Plastic valves with separating diaphragm for media containing ammonia in combination with CO₂ – with special media compatibility.
Hydrogen chloride filling:
Servo-controlled metal valves with special corrosion protection coating, durable at up to 40 cycles per minute.

Why our solution works

Our valves are created where they are needed: in dialogue with your application. This means we listen, question, calculate, test—and then build the perfect solution. Thanks to our modular system, even special solutions can be implemented in just a few days.

And the best part? Many requirements can be met with just a few targeted adjustments to existing components. This saves you time, money, and hassle—without compromising on quality or safety.
