 Model with aluminum actuator |
These butterfly valves controlled by a single-acting pneumatic actuator (normally closed or normally open), or a double-acting actuator, allow or shut off the flow of fluid. Only the sealing sleeve and the disc 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 (please consult us).
