Progressive Blocks
Progressive Block with one inlet & number of outlets is a hydraulic valve in block form which divides in going grease in equal metered amount with a help of plunger pins moving to & fro in the controlled holes of the segments.
With the input grease pressure, piston pins move to one side in sequence ejecting metered amount of grease. When passage is clear from last to first outlet, cycle is repeated.
Outlets from Progressive Block must be connected with lubrication points. DO NOT BLOCK ANY OUTLET OF PROGRESSIVE BLOCK. It will stop working in case of choking of any lubrication points.
To get the indication, one of the plungers is extended out. When this plunger moves, the indication pin can be visualized which ensures the working of the Block. Electric Sensing can also be monitored by providing Proximity Switch in the block.
