Innovation and investments: a pragmatic approach Hydrocontrol has always concentrated its efforts on being a reliable, proactive partner for both large OEMs and small and medium-sized manufacturers. Hydrocontrol’s decision to take an active part in designing and developing products for earth moving machinery is not only a strategic choice but is essentially it’s vocation. Over the past forty years of activity, this decision has enabled the company to reach all the major international markets, obtain important accolades, and become one of the world leaders in the production of hydraulic valves....

Living and working in the Global Market Hydrocontrol started its strategic activity of catering for the global market in 1998, since then we have opened subsidiaries in Europe, USA, China and India in order to be close and support the growth of these markets. The close proximity to the diverse markets has enabled us to understand their specific requirements, in many cases due to extreme working conditions, and by collaborating with local and global manufacturers of Mobile machinery we have found customised solutions. As a consequence of direct contact and problem solving activities with the Customer,...

Product range Hydraulic schematic - Sectional valve Parallel circuit When the spool is operated it intercepts the by-pass gallery by diverting the flow of oil to service port A or B. If two or more spools are actuated at the same time, the oil will power the service port that has the lower load; by throttling the spools, the flow of oil can be divided between two or more service ports. Parallel-Tandem circuit When the spool is operated it intercepts the switch gallery by diverting the flow of oil to service port A or B. The Tan- dem circuit is powered by the switch gallery thus permitting the...
