 Model with aluminum actuator |
These butterfly valves controlled by a single-acting pneumatic actuator, NC or NO, or a double-acting one, allow or prohibit the passage of the fluid. Only the sealing sleeve and the butterfly valve are in contact with the fluid. Models equipped with an MT-type actuator can limit the opening or closing angle of the valve depending on the stops used. (contact us)
