The Fisher 4660 pneumatic pilot-operated pressure controller activates a safe shutdown system for flowlines, production vessels, and compressors. The pilot is available in single or dual setpoint capability models that use a switching point to maintain full output pressure when the process pressure is within the set point range. If the process pressure is outside of this range, the pilot switches from full output pressure to zero output pressure. The main switching mechanism of this commander is the plugging and draining relay assembly. The structure can be used for plugging and excretion and plugging only systems.
