High-performance Rear Pump Regulator Valve For Construction Machinery Xcmg *******43 Kr3k-9n4a-v37t
New Products From This Supplier
The *******43 KR3K-9N4A-V37T Rear Pump Regulator Valve is a genuine XCMG OEM component designed to control and stabilize hydraulic pump output in excavators, wheel loaders, and other heavy machinery. Mounted on the rear of the main pump, this regulator maintains consistent system pressure under variable engine speeds and load conditions, preventing pressure spikes and ensuring smooth, efficient operation.
Manufactured to XCMG’s exacting standards, the valve body and spool are precision-machined from hardened steel, and sealed with high-performance elastomers to withstand pressures up to 25 MPa. Its built-in damping grooves minimize pressure oscillations, reduce noise, and protect downstream components from hydraulic shock. Direct-fit mounting and standard porting allow drop-in replacement with no modifications required.
