Hydraulic Rotary Unions

Rotary couplings transfer hydraulic oil from a fixed to a rotating machine part. The assembly is done in the rotating axis of the subassembly. Depending on the number of junction levels several single or double acting hydraulic elements can be connected. On principle,the rotary couplings is only suitable for hydraulic oil. Rotary Valve Couplings transmit hydraulic fluid to revolving tables. The structure is designed as a rotary slide valve, which permits several hydraulic devices to be supplied simultaneously with hydraulic fluid under pressure, and independently of that, a loading and unloading station to clamped or un-clamped by means of distributing valves.
