Rexroth R900450964 DR 6 DP2-53-75YM Direct acting proportional pressure reducing valve for Concrete Pump Truck Parts

Product Description/Features:
The direct-acting pressure reducing valve is directly driven by the secondary outlet pressure to open and close the valve, so that when the outlet pressure is less than the set pressure, the valve automatically opens, and the pressure adjustable range and the set pressure are associated with the valve to reach the full open position.

The product adopts a pressure balance design, which does not affect the export pressure due to fluctuations in the import pressure.

The pressure reducing valve is controlled by the control chamber to control the action of the valve, and the control chamber is communicated with the pressure behind the valve through the small hole. When the pressure behind the valve fluctuates, the control chamber pushes the action of the valve disc to keep the pressure stable, and the pressure gauge shows the pressure at the outlet.

Pressure reducing valve is a pressure control valve that uses the principle of hydraulic oil flow through the gap to produce pressure drop, so that the outlet pressure is lower than the inlet pressure.

According to different adjustment requirements can be divided into:

(1) Fixed pressure reducing valve: used to ensure that the outlet pressure is a fixed value of the pressure reducing valve
(2) Differential pressure reducing valve: used to ensure that the pressure difference between the import and export is unchanged
(3) proportional pressure reducing valve: used to ensure that the inlet and outlet pressure is proportional to the pressure reducing valve

Among them, the fixed value pressure reducing valve is the most widely used, referred to as pressure reducing valve.
