The DS type progressive distrbutor is composed of several valve block, including a first block, a tail block, and several working valve block.By continuously operating the plunger inside the working valve block, oil is supplied to each lubrication point point point by point. The working valve block of the distributor can be combined with dliferent displacement specifications to meet various displacement requirements. Intemasealing is used between each valve block, with high pressure rating and stable and reliable oil output. The distributor can be equipped with various cycle indicators to monitor the working status of the distributor, The DS type progressive distributor is divided into four types based ondisplacement specifications (DS1, DS2, DS3, and DS4). The mulf displacement specifications meet various working conditfons and can besuitable for high pressure and wide temperature changes.
