Hägglunds Launches New Valve Program
November 6, 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.
