VALVE GATE AND NOZZLE:
Spider (25): Visually inspect the fluid discharge areas for erosion and corrosion. Some wear is to be expected.
If any damage extends deeper than .06”, then replace part.
Valve gate (21) Nozzle (26), and O-ring (27): These are considered expendable items and spares should be
kept on hand at all times. The life cycle of these parts is dependent on the length and type of service.
Visually inspect the gate (21) and nozzle (26) for wear, pitting, erosion, or corrosion damage. These are critical
components to the function of the valve. Any indications of deterioration of sealing surfaces will require
replacement of the component. Lapping may be conducted on new seals to increase performance.
