Tri-Clover® 300 Series Valves
Tri-Clover's® classic 300 Series seat valves were the standard for food, dairy, and beverage process valves for many years. While this legacy valve series is no longer manufactured by Alfa Laval (now owner of the Tri-Clover brand), the valves are still supported. Genuine OEM spare parts and service kits are available for the maintenance and repair of 300 series valve.
The 300 series featured the 361 model shutoff and divert valves. 361 valves were available in a range of body styles, including reverse acting, as well as with several types of air actuators. The 371 line of valves were throttling (or regulating) valves. The aseptic 561 seat valve was also included in this series.
