What happens to the actuator if the filter regulator gets broken during the actuator stroke?

In case of filter regulator loss and output pressure from the compressor above the minimum one during the air stroke, the actuator will continue the travel with no excess of torque produced. Any eventual pressure above the minimum one will be applied on the mechanical end stopper at the end of the stroke. For most of our pneumatic actuators, such stopper is however designed to withstand a maximum supply pressure of 12 bar - see definition of MAWP above.
如果在上述滤波器故障和拖把值的气压供应上增加的条件下，阀在行驶期间卡住了，圆柱体产生的执行器输出扭矩可能会超过（取决于提供的入口压力）执行器和阀门也是如此。
Technically, if the actuator is selected considering both minimum and maximum supply pressure (by selecting the option 'Actuator MAST mandatory' in the sizing sheet) the actuator MAST issue disappears, but the output model is oversized in most of the cases with a non negligible commercial impact and probably issues on the valve MAST. A possible proposal to remove or at least reduce the extent of the oversizing is the introduction of a relief valve limiting the real maximum pressure far below the one available from the compressor.
