ABSTRACT:
The control valve includes a spring refiner which is threadly retained in the valve body and which may be adjusted so as to incrementally vary the hydraulic pressure required to open the valve. The valve additionally includes stops or limits so as to prevent the spring retainer from being grossly misadjusted which, when used in the hydraulic control system of the recloser, may cause undesirable miscoordination with the operation of other circuit breakers and protective devices. The valve additionally includes a self-locking mechanism to prevent the valve from falling out of adjustment due to vibration or improper handling.
