Cepex is a subsidiary of the international Fluidra Group. Since 1984 it has specialized in polymer engineering for fluid handling. Powered by thousands of tons of high-quality European resins each year and fully automated injection and machining lines, this Spanish brand ranks among Europe’s leaders in thermoplastic valves and fittings. A presence in 50+ countries and certifications to ISO 9001 and ISO 14001 underline that quality control and environmental responsibility are core to its strategy.
Materials & Manufacturing Engineering
Cepex manufactures its valves and fittings in four primary polymers:
- UPVC: Lightweight; resistant to common corrosives and chlorine.
- CPVC: Heat resistance up to 95 °C for hot and warm lines.
- PP-H: Excellent impact and mechanical strength; ideal for chemical industries.
- PVDF: Top-tier chemical and thermal resistance across thermoplastics; suited to strong acids and high-purity media.
Injection, machining, and assembly take place in Sabadell, Spain. Every valve undergoes 100% leak testing before shipment. True Union designs enable fast body removal for service and seal replacement, while Anti-Block technology in ball valves prevents ball lock-up under sudden pressure spikes.

Table 1 – Cepex Material Suitability vs. Service Conditions
| Polymer Type | Max Temp (°C) | Acid Resistance | Alkali Resistance | Typical Applications |
|---|---|---|---|---|
| UPVC | 60 | Good | Very good | Municipal water, pools |
| CPVC | 95 | Excellent | Excellent | Thermal services, boilers |
| PP-H | 90 | Very good | Excellent | Wastewater treatment, fertilizers |
| PVDF | 140 | Outstanding | Outstanding | Strong acids, pharma/high purity |
Engineering Advantages that Lower Lifecycle Cost
- Inherent chemical resistance: No corrosion; eliminates periodic replacement of metal components.
- Low weight: Up to 60% lighter than comparable metal alloys; easier handling and installation without cranes.
- Low pressure drop: Optimized hydraulic passages reduce pump energy.
- Easy maintenance: Double O-rings, two-piece nuts, and Union bodies minimize emergency downtime.
Key Applications
- Municipal water & wastewater: Transmission lines, pump stations, treatment plants.
- Chemical & petrochemical: Transfer of acids, alkalis, and deionized water with zero-leakage risk.
- Irrigation & greenhouses: Quick PP-Compression connections; UV resistance.
- Pools & waterparks: High durability in chlorinated environments; reliable filtration circuits.
- Food & pharma: Minimal metal contact with media; compatibility with NSF/WRAS requirements.

| Metric | Cepex (Spain) | Georg Fischer (Switzerland) | FIP (Italy) | Pimtas (Türkiye) |
|---|---|---|---|---|
| Track record (years) | 40 | 220 | 70 | 48 |
| Material breadth | UPVC / CPVC / PP / PVDF | Broad + metal | UPVC / CPVC / PVDF | UPVC / PP |
| Butterfly valve size range (mm) | 63–315 | 50–400 | 63–315 | 63–225 |
| Potable-water certification | ✔ | ✔ | ✔ | Limited |
Selection & Installation Notes
- For media above 70 °C, choose CPVC or PVDF.
- Account for allowable thermal expansion of plastic pipes in design.
- Solvent cement must match the line’s pressure/temperature class; typical full cure at ambient temperature is ~24 h.
- When installing butterfly valves in flanged systems, use a plastic-compatible backing ring to distribute pressure evenly.
