In the case of ball valves, mainly seats, gaskets, packings, bearings, thrust washers, etc. are consumable parts.
For the automatic valve, O-rings used in the actuator are also a consumable parts.

Metal parts are basically not consumable parts, but they may not be reusable due to disassembling, inspecting, or replacing parts caused by "the snap ring has spread out" or "the bolts and nuts have been caught".
In such a case, we can supply parts, so please contact our sales representative.
