Description

Spring return or double effect pneumatic actuator it opens btowing compressed air in the oullet chamber and it automaticaly doses bringing it back to almospbenc pressure. (see functional diagram) it opens biowing compressed air in the outlet chamber and it doses biowing the compressed air in the return chamber. (see functional diagram) TECHNICAL FEATURES OF THE ACTUATOR • - maximum operating pressure: 8 bar • - minimum air suppJy pressure: 6 bar • - rotation: 90° See the above-mentioned diagram. In the opening phase, the actuator provides a decreasmg output torque with the openmg degree. while maintaining the supply pressure constant. The lowenng is due to the fact that. in this phase, springs are subject to a deformation and absorb elastic potential energy. The aforementioned energy will be available during the closing phase. It’s during this second phase, in fact. that spnngs stretch out and do their duty. without the need of any external power. The cut-off torque is therefore characterized by 4 main values: Opening rotation: MAD: actuator torque with stretched-out springs MAC: actuator torque with compressed spring Closing rotation: MMC: compressed springs torque MMD: stretched-out springs torque
