On Demand Load Sensing
Most of Nimco’s open center valves as designed so that they can be ordered in load sensing version which we call ‘’ On Demand Load Sensing’’. On demand load sensing valves enable the valve to work in a system where a variable displacement pump is the source of oil and pressure supply.
The on demand load sensing valves will activate the pump when the spool is shifted from neutral position but does not offer individual pressure compensators for the spools.
A useful feature on some of these on demand Load Sensing valves is that it is possible to limit the maximum flow of any section which cannot be exceeded during any time of operation thus limiting the speed of any specific machine function without having to use a Load Sensing Valve equipped with pressure reducing valves in the cylinder ports.
