Rotating Unions
Rotating unions are a rotary connection, feeding pressure to fixtures while allowing full 360° rotation of the fixture with or without pressure. A machine or independent indexer may do this indexing. Rotating unions allow “live” hydraulic power to be supplied to fixtures during the machining cycle. Single, dual, quad and 6 path models are available to fit your application. G 1/4 models are required for major fluid distribution and all remote valve systems. G 1/4 models may be used on double acting systems and small single acting systems where speed of retraction is not critical. Most units may be either manifold mounted or used with standard fittings. Slip Rings are electrical rotary connections which can be operated with some models below. The leak free design eliminates the need for a drain or vent ports common on standard industrial models. This feature eliminates the need for continuous running pumps due to industrial grade rotary union leakage. All units include internal bearings to increase service life. Quad path models are often installed in machine doors to feed two independent dual path models on fixtures, making VektorFlo® the choice for all of your machine clamping needs. Integral mounting holes and multiple plumbing options make VektorFlo® designs easier to use than specialized larger industrial model. Standard Features for Single, Dual, Quad and 6 Flow Path Models
