It prevents the gate from slowly drifting down under load. When the valve's coil or internal seat wears, you'll typically see the platform sag, and replacing this valve/coil unit restores proper holding. This is the basic valve and coil; for a complete block-and-harness assembly, order Maxon 281308-01, and for a weather-protected version, use Maxon 282620-01.
