VALVE PLATE L - ERL-130B-RP-21-20NNN

Precision-engineered valve plate (Left-Hand Rotation) designed for Danfoss Sauer ERL-130B axial piston pumps (Series 45, RP-21-20NNN). This valve plate controls the port timing of hydraulic fluid flow within the pump, ensuring efficient displacement and smooth operation.

Application:

• Fits Danfoss ERL-130B pumps

• Commonly used in excavators, cranes, and other heavy-duty hydraulic machinery

• Works in combination with cylinder block, swash plate, piston shoe assembly, and retainer plate

Technical Details:

• Pump Model: ERL-130B (RP-21-20NNN)

• Orientation: Left-Hand Rotation (L)

• Function: Directs oil flow between pump’s high-pressure and low-pressure chambers

• Material: High-grade alloy steel with hardened and ground sealing surfaces

Purpose:

The valve plate ensures precise hydraulic timing and flow control. The L designation indicates it is for pumps with left-hand rotation, making it essential to match pump rotation when selecting replacement parts.
