DFR Pump Control Valve

DFR valve through the pressure control device and external throttle valve, changing the throttle valve opening can achieve the non-polar regulation of the piston pump output flow, regardless of the load size; By adjusting the standby pressure of the load sensitive valve to achieve the response speed.

Technical characteristics

• The flow at the outlet of the plunger pump does not vary with the pressure and is only related to the opening of the external throttle valve

• Good opening and closing characteristics ensure stable pump pressure and energy saving
  

• High strength and high elongation cast iron body for peak pressure of 45MPa

• Imported alloy steel wire spring ensures the long service life of the valve under high pressure
