Our mission is to develop, manufacture, and continuously improve high-quality plastic valves fittings for industrial piping and pool construction. The advantages of using plastic are numerous: it is chemically resistant, corrosion-free, and has low thermal and electrical conductivity. We keep raw material consumption to a minimum through optimized production processes and the long service life of our products.
Your Advantages When Using Plastic
Low weight due to low density (contributing to a positive environmental footprint)
Cost-effective due to extended operational lifespan
Environmentally sound due to recyclability
Chemically resistant and abrasion-proof
Corrosion-resistant
Low thermal and electrical conductivity
Minimal condensation formation, no electrolytic corrosion
Environmentally sound due to recyclability
Resistant to impact loads and flexural stress
Smooth surface prevents incrustation and associated pressure loss

The thermoplastics we use
We process a wide range of technical and high-performance thermoplastics. The following list shows a selection of the materials we frequently use. Depending on the requirements, other suitable plastics may also be used.
Unplasticized Polyvinyl Chloride (PVC-U)
PVC-U (unplasticized PVC or rigid PVC) is manufactured without the incorporation of plasticizers. Rigid PVC is a thermoplastic employed across a broad spectrum of applications, owing to its superior chemical, corrosion, and weather resistance. Furthermore, PVC-U components are suitable for potable water and food contact applications, having been demonstrably proven physiologically inert.
Chlorinated Polyvinyl Chloride (PVC-C)
PVC-C exhibits superior temperature resistance, enhanced material strength and toughness, and improved chemical resistance compared to PVC-U.
Praher's Corzan® PVC-C industrial piping system components demonstrate resilience against aggressive chemicals at elevated temperatures (up to 80°C). They are widely deployed across diverse sectors, including the chemical process industry, metal finishing, chlor-alkali production, and the pulp and paper industry, among others.
Polypropylene (PP-H)
PP is a semi-crystalline material characterized by a lower density compared to other commonly utilized thermoplastics. It possesses excellent mechanical properties, exhibits resistance to a broad spectrum of media, and maintains high heat deflection temperature. For industrial applications, three types of PP are employed: the isotactic homopolymer (PP-H), the block copolymer (PP-B), and the random copolymer (PP-R). Owing to its superior homogeneity, PP-H is the preferred choice for manufacturing industrial valves.
Polyvinylidene Fluoride (PVDF)
PVDF is a semi-crystalline thermoplastic synthesized from vinylidene fluoride via emulsion or suspension polymerization. Polyvinylidene fluoride is classified among the fluoropolymers, offering a unique combination of attributes: exceptional chemical resistance, high thermal stability, and superior mechanical properties. PVDF demonstrates outstanding pressure-temperature performance and singular resistance to gamma radiation, thereby enabling its deployment in highly specialized applications compared to other thermoplastics.
