KMX13 316-2157 Control Valve Assembly Overview
The KMX13 316-2157 Control Valve assembly manufactured by Tatan is a sectional multiple-spool hydraulic distribution unit belonging to our Main Control Valve Assembly classification. Engineered specifically for Caterpillar CAT 307, 307B, 307C, 307D, and 307E 7-to-8-ton compact excavators, replacing your worn valve with a Tatan complete assembly eliminates boom sinking, restores dozer blade holding stability, and cures internal pressure bypass across demanding utility trenching and civil construction applications.
Powered by the machine’s main hydraulic pump and matched with the diesel engine platform, this KMX13 316-2157 Control Valve integrates micro-lapped alloy spools, load-check poppets, auxiliary thumb/breaker circuits, and a dedicated dozer blade section, ensuring 100% direct bolt-on installation with chassis hydraulic hard lines and pilot control hoses.

KMX13 316-2157 Control Valve Diagnostic & Troubleshooting Guide
Use this technical guide to diagnose common hydraulic control valve issues on Caterpillar 307 series excavators:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Boom drops or drifts downward during neutral hold | Boom holding check valve poppet seat wear or port relief valve O-ring leakage allowing pressurized fluid to pass to tank. | Replace with Tatan complete KMX13 316-2157 Control Valve assembly with factory pre-seated holding check poppets. |
| 2. Machine veers off course when traveling and blading together | Flow-splitter spool sticking or internal load check poppet seat wear causing unequal flow distribution to travel motors. | Inspect straight travel pilot pressure; install Tatan pre-calibrated replacement valve to restore balanced flow. |
| 3. Auxiliary attachment weak (breaker / auger stalls) | Auxiliary section port relief valve spring fatigue or foot-pedal pilot actuator shuttle spool contamination. | Clean pilot passages, verify 28.0 MPa relief setting, or bolt on brand-new complete control valve assembly. |
| 4. External fluid seepage between valve sections | Tie-rod bolt elongation or inter-section fluororubber O-rings degraded from continuous oil temperatures over 80°C. | Install new Tatan sectional valve pre-torqued with industrial O-rings and calibrated tie-rod fasteners. |
