Plastic Valves for Corrosive Media and Industrial Applications
When media corrode metal, temperatures fluctuate, or high chemical loads occur, many standard valves quickly reach their limits. This is exactly where our plastic valves come into play. We develop and manufacture plastic valves for applications where durability, controlled flow, and long-term operational reliability are critical.
Our plastic valves are used worldwide in chemical engineering, the process industry, medical technology, water treatment, refrigeration technology, and plant engineering. Using various materials such as PTFE, PVDF, PVC, or PP, we tailor each solution to the specific medium, pressure range, and application.
Plastic Valves for Corrosive Media and Complex Processes – Typical Challenges
In many industrial plants, traditional metal valves are not sufficient. Highly corrosive media such as sulfuric acid, hydrochloric acid, sodium hydroxide, or chlorine-containing liquids cause permanent damage to conventional materials. At the same time, requirements for process safety, maintenance intervals, and plant availability are increasing.
Common Challenges with Plastic Valves in Industry:
- chemically aggressive liquids and gases
- Corrosion in Metal Fittings
- strict requirements for leak tightness
- varying pressure and temperature ranges
- sensitive media in the pharmaceutical or medical technology industries
- abrasive or contaminated media
- compact installation spaces
- high switching frequencies
- Long maintenance intervals required
- Minimal downtime in production facilities
In chemical engineering and industrial refrigeration in particular, unsuitable valves often lead to leaks, increased maintenance costs, or unplanned production stoppages. Many operators are therefore specifically looking for plastic valves with high resistance to process media and a long service life.
Plastic valves in plant engineering offer economic advantages
Our plastic valves are not used solely because of their chemical resistance. Many customers deliberately choose plastic valves because they offer economic benefits during operation.
Advantages of our plastic valves:
- High resistance to aggressive media
- lightweight compared to metal valves
- reduced corrosion problems
- long service life
- low maintenance costs
- high process reliability
- low pressure drop
- compact design

- high airtightness
- Cost-effective integration into existing facilities
- customization options
In modern process plants in particular, every instance of unplanned maintenance counts. That is why, right from the valve design stage, we ensure that the materials, seals, and control system are precisely tailored to the application.

Plastic Valves in Chemical Engineering, Medical Technology, and Refrigeration Technology – Project Examples
Our plastic valves are used worldwide in a wide variety of industries.
At a chemical production facility, PVDF plastic valves were used to safely control highly corrosive acids over the long term. Switching from metal valves to plastic valves significantly reduced corrosion damage.
A manufacturer of water treatment systems uses our plastic valves with PTFE bellows for media containing chlorine. As a result, the system achieves longer maintenance intervals and greater process stability.
Our plastic valves are also used in medical technology, for example in sensitive gas control systems or laboratory applications with high requirements for media purity and leak tightness.

Plastic Valves Made of PTFE, PVDF, PVC, and PP—Why Material Selection Is Crucial
Choosing the right material is often crucial to the service life of a plastic valve. Different media react in completely different ways to temperature, pressure, and chemical exposure.
PVC plastic valves are particularly well-suited for many traditional industrial applications involving moderate temperatures and requiring high chemical resistance.
PTFE valves are used when particularly aggressive chemicals are involved or when high sealing performance is required. Thanks to their low friction and high temperature resistance, they are suitable for demanding processes.
PVDF plastic valves offer very high resistance to corrosive media while also providing good mechanical properties.
PP plastic valves are often used when a cost-effective solution with good chemical resistance is required.
Thanks to our experience in valve design, we assist customers early on in selecting the optimal material.

FAQ – Plastic Valves for Technical Applications and Industrial Processes
Plastic valves offer significant advantages, particularly when handling aggressive media. Many chemicals cause permanent damage to metal, whereas materials such as PTFE, PVDF, or PVC are significantly more resistant. In addition, plastic valves are lighter, corrosion-free, and often require less maintenance. This leads to lower long-term operating costs, especially in chemical plants and water treatment facilities.
Our plastic valves are suitable for a wide range of corrosive, neutral, and gaseous media. These include, among others, acids, alkalis, chlorine gas, sulfur dioxide, nitrogen oxides, hydrogen, CO2, cleaning agents, and solvents. The specific material selection always depends on the temperature, pressure range, and medium.
PTFE is used when particularly high chemical exposure occurs or maximum sealing performance is required. The material has very high resistance to aggressive chemicals and is therefore suitable for demanding applications in chemical engineering, the pharmaceutical industry, and laboratory facilities.
Media isolation protects sensitive valve components from direct contact with corrosive media. This significantly reduces corrosion, material wear, and leaks. Especially when handling highly reactive substances, this increases operational safety and significantly extends the valve’s service life.
Yes. Depending on the material, design, and configuration, plastic valves are also suitable for demanding pressure ranges. The key factors here are the medium, temperature, and desired operating cycles. That is why each valve is individually tailored to the application.
Plastic valves are used in a variety of fields, including chemical engineering, water treatment, medical technology, food processing, the process industry, refrigeration technology, energy technology, and plant engineering. Plastic valves demonstrate their advantages particularly in applications involving corrosive media or where high sealing requirements are necessary.
Direct-acting plastic valves are actuated directly by the actuator and are particularly suitable for fast switching operations or smaller nominal diameters. Servo-actuated valves additionally use the fluid pressure to assist the switching process. This allows for the energy-efficient control of larger flow rates.
When designing a valve, we consider the medium, temperature, pressure range, operating frequency, installation conditions, and desired service life. We then select suitable materials, seals, and control types. This results in a solution that is technically and economically optimized for the application.
