Recirculating system 7142A Regulator
The 7142A Regulator can also be used for reducing compressed air supply pressures on the TwinBed II pneumatic control system.
The 7142A Regulator should be installed in the compressed air piping upstream of the cycle control solenoid valves when the plant air supply exceeds 70 psi. A constant supply pressure is desired to avoid cyclic pressure swings. (Reference TwinBed II Pneumatic Piping Schematics 1444A.) SCFH CAPACITIES COMPRESSED AIR
