Alfa Laval 650/655 Series Fractional Valves

The 650 and 655 Series of fractional valves from Alfa Laval were a range of valves in fractional sizes, including shutoff or divert valve bodies and manual or air-actuated models. This legacy valve series is no longer manufactured by Alfa Laval. However, many genuine OEM spare parts and service kits are available for the maintenance and repair of 650 and 655 series valves.

The 650/655 Series featured a sanitary design with multiple options in fractional (1/2" and 3/4") sizes. 650 valves were shutoff body styles, with manual, air-actuated, or relief valve options. 650 valves were available with two plug seal options: the lip seal or the o-ring seal. The 655 series of divert valves were air-operated, with molded elastomer seats.
