摘要： The invention concerns pneumatic actuators for valves comprising a body closed by head flanges, two pistons moving in said body in opposite directions, an output shaft that turns actuated by the pistons, and a stop device on each head flange to limit the stroke of the pistons when they move away from each other towards the head flanges. On at least one side of the actuator body an adjusting device (22) is provided which includes stop means (26, 27) at varying distances from each other in a direction parallel to the movement of the pistons and arranged in a position to intercept and limit the stroke of the pistons when the latter move towards each other.

摘要： The invention concerns a coaxial valve, particularly for the delivery of chemically aggressive fluids in the pharmaceutical and medical sectors and also for use in the food industry. The opening and closing of the valve is achieved in a combined pneumatic and magnetic actuating system, realised with the help of a pneumatic piston-actuator (13) and an obturator (14) positioned in parallel chambers, separated and constrained one to the other by means of permanent magnets (30,32) for the movements of the obturator in opposite opening and closing directions in response to the movements of the piston-actuator caused by a fluid under pressure.

摘要： The invention concerns a releasing device (30) to be inserted between a power actuator (20, 87) for valves and a valve (10) to be controlled. It comprises a driving component (36) to be interfaced with the power actuator (20), a driven component (37) to be interfaced with the shutter of the controlled valve (10), and a connecting component (38) all rotating of at least 90° around the same axis (X). The connecting component (38) is provided with clutching means (50) to catch both with the driving component (36) and the driven component (37), or with the driven component (37) only. When the connecting component (38) is caught to the driving component (36), this causes the opening and closing rotations of the shutter of the valve (10) and the loading of return springs (60, 60'); when the connecting component (38) is caught to the driven component (37) only, this causes the shutter of the valve (10) to rotate rapidly in its closing direction due to the action of the return springs (60, 60') connected therewith.
