Progressive Blocks

Progressive Blocks

A Progressive Block is a hydraulic valve in block form with a single inlet and multiple outlets. It efficiently distributes grease into equal metered amounts using plunger pins that reciprocate within controlled holes in the segments. Under input grease pressure, the piston pins sequentially move to one side, ejecting precise quantities of grease. Once the grease completes its passage from the last outlet back to the first, the cycle repeats.

Each outlet of the Progressive Block must be connected to a lubrication point. Blocking any outlet will disrupt the operation, as the system ceases to function if a lubrication point becomes clogged.

To monitor functionality, one of the plungers is designed to extend outward. When this plunger moves, the indication pin becomes visible, confirming the block's operation. For enhanced monitoring, an electric sensing system can be integrated by fitting a proximity switch into the block, providing real-time operational feedback.
