Alfa Laval 660 Series Fractional Valves

Alfa Laval's 660 Series fractional valves from Central States Industrial (CSI) offer convenient manual operation in a fractional size valve. Alfa Laval designed these valves for applications which require a secure, sanitary or sterile environment.

Tri-Clamp® or hose barb outlets make this valve versatile for standard shutoff or sampling purposes. CSI also offers valve modification to fit specialized applications.
