multiple-spring diagram actuator
AoTu-D1 Series multispring pneumatic diaphragm actuators are designed to provide high performances in both direct and reverse acting configuration.
The thrust is supplied by a rubber, air-Ioaded diaphragm or, in the opposite configuration, by helical springs.
Standard model can be delivered either as direct-acting actuator (model 1-D11) or as reverse-acting actuator (model 1-D12), with any component change.
Where pneumatic cilynders are not applicable, double-diaphragm execution for type D63 is avaiable to perform high sealing class on very high pressure drops.
The series is composed by 6 actuator sizes: D12, D25, D33, D39, D46 and D63.
