Anti-Syphon Valve Spring, 6 PSI

The Blue-White Industries C-354-2 is a genuine OEM replacement anti-syphon valve spring specifically engineered for use with the C-600HV series diaphragm metering pumps. This precision component is calibrated to maintain an opening pressure of 6 PSI, which is critical for ensuring accurate chemical dosing and preventing back-siphonage into the chemical feed lines. Designed for high-volume (HV) applications, it is often found within injection check valve assemblies where it provides reliable resistance in demanding water treatment, pool, or spa environments.
