Tri-Clover® 100 & 200 Series Valves

The original 100 and 200 Series seat valves, including 241 and 161 valves, are a legacy valve series originally manufactured by Tri-Clover®, now Alfa Laval. The majority of these valves are no longer manufactured by Alfa Laval. However, many genuine OEM spare parts are available for the entire valve series.

This valve series included a variety of models and valve types. The 161 line included both shut-off and divert style valve bodies, with either a normally open or normally closed actuator. 241 and 262 models comprised several tank and kettle style valve bodies. The 171 line of throttling valves included both the air-actuated throttling valves and the 171-10M-90 micrometer valve, a manual valve with a fine adjustment knob. The 171-10M-90 micrometer valve continues to be manufactured by Alfa Laval.

Also in the 200 series of valves was the 262-121 Flo-Diversion valve. This valve, as well as the later 762-121 and 762-227 Flo-Diversion valves, are used in dairies for controlling product flow in HTST pasteurization systems.
