Rola-Chem 521170 Injector Check Valve

Ensure precise pool chemical dosing with reliable backflow protection

The Rola-Chem 521170 Injector Check Valve is a compact inline valve designed for use with pool chemical injectors and dosing manifolds. It provides one-way flow to prevent backflow into the injector and downstream lines, helping maintain dosing accuracy and protecting upstream equipment. Designed to integrate with standard pool chemical injection fittings and feed lines, this valve is a practical choice for maintaining a reliable chemical dosing setup.

Construction, Compatibility and Integration

Built for durability in chemical environments, the 521170 uses a corrosion-resistant polymer body and precision-sealed internals to minimize leakage and maintain reliable operation in pool systems. Its inline form factor is intended for straightforward installation in the injector feed line, compatible with common fittings used in pool chemical dosing hardware. This design helps keep plumbing simple and reduces the risk of backflow contaminating the dosing supply.
