HVME400-060000 Main Safety Valve (Main Spool of Distributor Valve) Original Factory Parameters
Hengli Part Number: HVME400-060000 | 02.02.09.00088
Sany Material Code: 150688000155
Compatible Valve Body: Hengli HVME400 Multi-way Valve (Sany 150601080024A Main Control Valve Assembly)
I. Compatible Machine Models (Dedicated to National IV Hengli Valves)
SY365H, SY375H, SY395H, SY415H, SY485H (Equipped with HVME400 distributor valve; cannot replace old Kawasaki KMX32 main spools)
II. Basic Parameters
1. Original Factory Standard Set Pressure: 32.5 MPa (325 bar), Overload Opening Pressure 34.5 MPa, Main Machine System Maximum Pressure Limiting Valve
2. Installation Location: Upper end of the oil inlet manifold block on the distributor valve, main pressure protection spool for the entire machine
3. Structure: Pilot-operated relief valve, consisting of a pressure adjustment screw, main spool, and pressure adjustment spring assembly, integrated cartridge structure
III. Core Functions
1. System Overload Pressure Relief: Relieves pressure when the boom is jammed or the machine stalls, protecting the main pump and distributor valve from explosion due to overpressure
2. Limit Main Machine Pressure: Determines digging force. Low pressure → weak excavator performance, slow lifting; High pressure → stalling, oil pipe bursting, easy damage to hydraulic components
3. Load-Sensitive Pressure Stabilization: Cooperates with the HVME400 positive displacement system to stabilize the main pump output pressure
IV. Common Faults
1. Spring Fatigue / Spool Scoring Leading to Internal Leakage: Weak operation throughout the machine, pressure not rising, adjusting the pressure adjustment screw ineffective
2. Stuck Spool in Constant Open Position: System low pressure, stalling under no load, high fuel consumption
3. Sealing Damage: External leakage of hydraulic oil from the valve body
V. Product Differentiation
- Original Factory New: Hengli original coded parts, factory preset pressure, can be installed directly without repeated pressure adjustment
- Aftermarket Parts: Unstable spring elasticity, easy pressure drift, high failure rate under heavy mining loads
