and proportional directional valves automatically isolate the load from the load-sense network when they are de-energized. Load-holding valves are not needed unless there are overrunning load conditions that require the use of counterbalance valves. In any application where there is a need for multiple functions to operate simultaneously, and a need for speed to remain independent of load pressure, a flow-on-demand type compensator can easily be connected to the load-sense lineto provide...

on/off delivery of coolant to the toolhead in fractions of a second. 3) The flow must be manually adjustable when required. 4) The valve must integrate an adjustable bypass to maintain constant coolant flow in the event the primary port is closed. 5) The valve must accommodate dual pressures simultaneously. The co-ax® valve in this case is a 4-unit modular valve configuration. One of the units is fitted with an isolation plate to allow a different operating pressure on demand. The OEM's material...

to achieve higher safety records. Due to safety critical testing limitations, these two requests tend to contradict one another. In reality, these opposing concepts can easily be achieved through periodic partial stroke testing. Maxon's patent pending PSTrend technology, applied to Maxon's Series 8000 safety shut-off valves, trends test results to help predict a valve's probability of failure on demand. Maxon's proven metal-to-metal seating technology actually benefits from repeated full... (read more)Browse Gas Valves Datasheets for Maxon - A Honeywell Company

Valves do double duty
over their fixed-displacement counterparts. Fixeddisplacement pumps always deliver the same flow, regardless of demand. So if the crane sits idle, all the flow dumps to the tank in an inefficient waste of energy. Variabledisplacement, loadsensing pumps, however, only provide the flow required
