Hägglunds Launches New Valve Program

Thursday, November 06, 2003
Hägglunds Drives launched a new valve program designed to optimize the full potential of their Compact brand industrial motors. Hägglunds hydraulic Compact motors have a reputation for their wide speed and power range. Only a few of the valves available on the market have so far proven to be suitable for the flow capacity of these motors, according to Hägglunds Business Segment Manager Ingemar Borg. To match the Compact motors capabilities to stand tough environments, the design of these new valves is compact and robust, corrosion resistant and completely sealed. There are huge variations in the drive performance requirements for marine, industrial and mobile business. Hägglunds new valve program is engineered in order to meet these demands. This standard valve program includes crossover relief valves, counter balance valves, two-speed valves, four-way proportional valves, freewheeling valves, free-circulation valves as well as constant tension valves. "We really put some tough demands on the design specification from the start," Borg said. "We did not want too many valves and we wanted to be able to combine various valves to produce multifunctions." The valves have already proven successful on several demanding marine applications. For example in a winch drive system in South Africa, lifting a 178 metric ton sub-sea crawler back and forth from the seabed to the ship deck, as well as on a large number of fishing boats manufactured in Spain.
