Plastic valves – The engineered choice for demanding applications
High-quality plastic valves have become indispensable in modern industry. They offer a reliable solution for regulating and controlling a wide range of media in industrial processes. Plastic valves stand for quality, durability and high resistance to a wide range of media.
Advantages of plastic valves
Plastic valves offer numerous advantages over conventional valves made of metal or other materials:
Corrosion resistance: Excellent protection against rust and wear.
Chemical resistance: Ideal for use with aggressive chemicals.
High resistance: Particularly resistant to abrasive media.
Lightweight construction: Easier to install and handle thanks to the lower weight.
Media resistance and durability
Plastic valves are characterized by their exceptional resistance to various media. They are ideal for a wide range of media types, including:
-
Liquid media: e.g. hydrochloric acids, aggressive cleaning agents, chlorine, acetone, perfumes, alcohols, detergents, bleach and battery acid.
-
Gaseous media: e.g. chlorine gas, ammonia, sulfur dioxide, nitrogen oxides, carbon dioxide, hydrogen, oxygen, helium, argon and nitrogen.
-
Aggressive media: e.g. hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, acetic acid, sodium hydroxide, potassium hydroxide, calcium hydroxide and ammonium hydroxide.
These properties make plastic valves ideal for use in demanding industrial environments where high resistance to various chemical substances is crucial.
Versatile applications
Plastic valves offer a wide range of applications in various industries. Whether in the chemical industry, food and beverage production or water treatment - these valves offer a reliable solution for the precise control of processes. Their versatility and robustness make them a smart choice for numerous industrial applications.

Housing materials for plastic valves
Plastic valves are available in various housing materials, each offering specific advantages for different applications:
PVC (polyvinyl chloride): A widely used plastic known for its excellent resistance to chemicals and corrosion. PVC valves are particularly suitable for use in aggressive environments.
PTFE (Polytetrafluoroethylene): A high-performance plastic known for its excellent chemical resistance and low friction. PTFE valves offer exceptional performance and are ideal for applications with high corrosion and chemical resistance requirements.
PVDF (polyvinylidene fluoride): A thermoplastic fluoropolymer that offers excellent resistance to aggressive chemicals and high temperatures. PVDF valves are very durable and suitable for demanding industrial environments.
PP (Polypropylene): A versatile plastic known for its high chemical resistance and strength. PP valves are lightweight, robust and offer excellent resistance to various chemicals, making them a cost-effective solution for numerous applications.
Connection types
Various connection types are available for the installation of plastic valves:
Adhesive connectors: Enable easy and quick connection of plastic pipes.
Welded sockets: Provide a durable and tight connection suitable for demanding applications.
Threaded sleeve: Allows flexible and easy assembly and disassembly.
Types of operation
Plastic valves are available in different actuation types to meet different requirements:
Direct-operated: These valves open and close directly through an electric or pneumatic actuator. They offer fast and precise control of the medium and are particularly advantageous for applications with short response times or frequent switching operations. Direct-operated valves are characterized by their compact design and more cost-effective production compared to servo-operated valves.
Servo-controlled: Servo-controlled valves use an actuator that is precisely positioned by an external control signal (e.g. 4-20 mA). This type of valve allows continuous and precise control of the flow and is particularly suitable for applications where precise dosing or consistent control over longer periods of time is required.
Conclusion
Plastic valves offer a reliable solution for regulating and controlling a wide range of media in industrial applications. Their outstanding media resistance, versatility and durability make them an ideal choice for demanding environments.
