Sanitary valves Working principle
Sanitary valves can be driven by electric or pneumatic actuator, with signal to automatic control the valve open and close. The actuators rotate the discs freely within 90° to open or close or regulate the flow of the medium.

Sanitary valves Leakage Class
Soft sealing butterfly valve: Zero leakage
Metal hard seal concentric butterfly valve: 1% leakage
Metal hard seal double/triple eccentric butterfly valve: Zero leakage
