Sany Original 150601080024A Hydraulic Control Multi-way Valve HVME400-000000-014, suitable for SY365H/SY375H/SY395H/SY415H/SY485H/SY500H models

Original Factory 150601080024A | HVME400-000000-014 Hydro-Control Multi-Way Valve Full Analysis
I. Model Code Explanation
1. Sany Part Number: 150601080024A: This is the original factory drawing number from Sany Heavy Industry, serving as the whole machine parts library code for assembly of SY series excavators and for after-sales ordering traceability.
2. Valve Body Model: HVME400-000000-014: OEM custom model by Hengli Hydraulics.
- HVME = HVS-E Series hydro-controlled positive displacement multi-way master control valve from Hengli; 400 = Port size specification (32mm port, rated flow level of 400L/min); suffix 014 represents the valve plate configuration scheme (5-way main valve + auxiliary overload valve layout, corresponding to dual spool configuration for the boom).
II. Compatible Models (Sany 35~50-ton Class Large Excavators)
Mainly compatible with: SY365H, SY375H, SY395H, SY415H, SY485H (standard equipment on new National IV models, replacing old Kawasaki KMX32 distributors). The same series HVME400 also equips domestic 45-ton class mining excavators such as Liugong 950 and XCMG 490.
III. Core Technical Parameters 
| Item | Parameter Value |
| Control Method | Pilot hydraulic control, positive displacement control system (matching K7V160/K7V180 main plunger pumps) |
| System Rated Pressure | Main oil circuit 35MPa, Overload protection 42MPa |
| Nominal Bore | 32mm, Maximum single-way flow 400L/min |
| Valve Plate Layout | 5-way main control: Dual valve plates for boom + Bucket cylinder + Rotation + Travel, integrated main overflow valve and individual overcharge make-up valves |
| Manufacturer | Jiangsu Hengli Hydraulics (Sany's designated original factory配套 supplier) |
IV. Valve Body Structure Breakdown (Referencing Real Photos)
1. Upper Cylindrical Assembly: Each section corresponds to a main overflow valve + overcharge safety valve assembly (yellow vertical cylinders, adjustable system pressure and anti-shock suction make-up).
2. Valve Body Main Block: Split-cast steel valve block, divided into left/middle/right three valve groups, integrating main spools and pressure compensation valves internally.
3. Side Small Valves: Load-sensitive logic valves, regeneration valve blocks (014 model exclusive boom regeneration oil circuit, enhancing lifting fuel efficiency).
V. Parts and Maintenance Key Points
1. Consumable Parts List: Main spools for each way, overcharge valve spool assemblies, valve rod oil seals, valve body O-ring seal kits;
2. Common Faults: Valve core sticking caused by oil impurities (slow operation / stalling), fatigue of overcharge valve springs (boom drop, depressurization);
3. Replacement Notes: The -014 suffix denotes an exclusive boom dual-spool regeneration structure; HVME400 valve bodies with other suffixes (-011/-043) must not be mixed.
VI. Product Attributes
- Original New Parts: Installed in Sany host machines, featuring yellow original high-temperature baked paint;
- Salvaged Parts: Second-hand refurbished valve bodies circulating in the market, commonly used for repair replacement of old machines.
