Why the use of a relief valve after the filter regulator?
The relief valve acts as a further protection in addition to the filter regulator as it limits the maximum air pressure to the cylinder in case of filter regulator malfunctioning. We foresee its presence in the actuator control system if:
- the maximum air supply pressure exceeds the actuator MAWP
- customer specifically asks its presence in the panel
- customer requires the actuator's torques developed at the maximum supply pressure and the same exceeds the actuator MOP. The introduction of a relief valve set below such maximum pressure avoids or reduces the actuator oversizing.
