Motor Operated Valve

Answer / kj

Most likely what you are looking at is a Metal Oxide
Varistor. This a a component which will start to conduct
when the voltage across it reaches a pre-designed level.
They are normally used to absorb spikes where these can
damage electronic components. Placing a MOV across the
input will shunt any spikes through the MOV and prevent it
from damaging other components.
