Directional Control Valve Equipment for Front End Loaders
nimco-controls.comComplete control. One of the most critical factors for any loader operator today is absolute control of the load at all times. This is made easier by the use of well-designed valves that include load holding check valves and ‘turned’ spools which not only allow the operator to have absolute control
Specalog for 140H Motor Grader, AEHQ5449
crosscountryis.comImplement Control Valves. PPPC valves have different flow rates for the head and rod ends of the cylinder. This insures consistent extension and retraction properties for each cylinder, and improves operator ‘feel’ and system response. All control valves use lock valves to maintain blade settings. Line relief valves protect cylinders from
