The 503/31 block valve locks the cylinder in its current position when pressure drops, thereby preventing uncontrolled lowering of the raised tipper body.

It differs from related types by the port diameter – M18x1.5 instead of M20 or M36. The wrong type requires adapters, which introduce additional leak points.
