The valve is a Crosby, Model HB-BP-86 Type E, self-actuating spring type safety valve. The vendor estimated that the actual lift pressure would have been 3530 psig, 1045 psig above the nominal setpoint pressure of 2485 psig. The vendor determined that the cause of the setpoint change was due to the spindle being engaged in the disc holder located within the valve. Proper assembly of the valve requires that the spindle be inserted past the threads of the disc holder until it turns freely. This was not performed during the jack-and-lap evolution and was determined by the vendor to be an isolated instance of human error.
