⚙️ PVDF Injection Valve – Ball & Spring Type (FPM / Ceramic Wetted Parts)

This PVDF Ball & Spring Injection Valve is a high-quality non-return dosing accessory designed for reliable chemical injection in pool water treatment, industrial dosing, and filtration systems.
Manufactured with PVDF, FPM elastomers, and a ceramic check mechanism, it offers excellent chemical resistance, long service life, and stable dosing performance even under continuous operation.

Supplied as standard equipment with most professional dosing pumps, this injection valve ensures precise chemical delivery, prevents backflow, and protects the pump and dosing line from pressure fluctuations.

✅ Key Features
