Saf-T-Flo Chemical Injection

SAF-T-FLO Chemical Injection, based in Placentia, California, manufactures retractable and non-retractable chemical injection quills and flexible hose assemblies for delivering treatment chemicals into pressurized piping systems at water and wastewater treatment plants. The company’s flagship product line comprises four series of retractable injection quills that allow safe insertion and removal without system shutdown—critical because many treatment chemicals form deposits that clog injection ports over time. The Standard Service series handles process pressures up to 150 PSI with chemical feed sizes from 1/4 to 2-1/2 inches, offering the widest range of sizes, materials, and features. The Heavy Service (HS) series is rated to 250 PSI with dual-bolt restraint and all-alloy construction for large-diameter or turbulent process lines, available in models HS-075 through HS-300 (3/4 to 3 inch valve sizes) with SAF-T-Seal or integrated check valve options. The High Corrosion Resistant (HC) series shares the HS platform but uses specialty alloy materials for aggressive chemical environments, spanning models HC-075 through HC-300. The Flanged (FL) series uses flanged rather than threaded process connections for large-diameter lines, available in models FL-075 through FL-300. Non-retractable injection quills and flexible hose assemblies complete the product range, serving chlorine, coagulant, pH adjustment, and other chemical dosing applications throughout treatment facilities.
