Typical Applications:
Hygienic Butterfly Valves are universal valves for isolation and
control, in the food, dairy, brewing, pharmaceutical and beverage
industries. These butterfly valves are designed to be easily
automated with the SS Actuator, combined with the Easymind
Electronic Control Top. Other automation options can also be made
with other Pentair rack and pinion actuators upon special request.
