Sany Original Equipment Allocation Valve Linear Travel Valve Core Assembly HVME400-TS01-ASSY 02.02.10.00197, Sany Material Code: 150688000139

HVME400-TS01 Linear Travel Valve Spool Assembly | Sany Original Parts Explanation
I. Model Code Explanation
1. Part Number: HVME400-TS01-ASSY 02.02.10.00197
Compatible Valve Body: Hengli HVME400 (Sany 150601080024A Multi-way Main Control Valve). TS01 is the exclusive component code for the linear travel valve. ASSY denotes the valve spool assembly (complete set including valve spool, reset spring, and limit washers).
2. Sany Material Number: 150688000139
Sany ERP original order code, used for after-sales procurement and whole machine assembly配套 for SY365H/SY375H/SY485H.
II. Compatible Models
Assembly Compatibility: Sany SY365H, SY375H, SY395H, SY485H Euro IV models (dedicated to HVME400 main control valve).
Only compatible with Hengli HVME400 series distributor valves; not interchangeable with old Kawasaki KMX32 valve bodies.
III. Structural Disassembly (Refer to Actual Photos)
1. Main Valve Spool Rod: Quenched and tempered alloy steel, surface precision ground and chrome-plated, featuring multiple annular throttling grooves and radial oil control holes. It switches oil circuits by moving the valve spool.
2. Positioning Snap Ring Seat: A middle-slotted tooth ring structure that limits the maximum travel of the valve spool and controls the opening of the linear travel oil ports.
3. Rear Reset Spring Assembly: Heavy-duty high-temperature alloy compression spring with limit washers. After the pilot oil pressure is released, the spring pushes the valve spool back to the neutral position, disconnecting the linear travel function.
IV. Functional Principle 
Linear Travel Valve = Core Component for Excavator Confluence Straight Travel
1. During travel operations, pilot oil pushes the valve spool against the spring to shift, directing the combined supply from both pumps to the two travel motors.
2. Enables simultaneous operation of the boom/ dipper stick without deviation during travel, solving issues of deviation with single-pump supply and weak travel performance.
3. Neutral Position: The spring returns the valve spool to neutral, allowing the left and right pumps to independently supply oil to the left and right travel systems, ensuring normal conventional steering actions.
V. Common Faults and Maintenance
1. Fault Phenomenon 1: Travel deviation, deviation when retracting the boom → Valve spool sticking (valve rod scratched by hydraulic oil impurities, throttling holes clogged).
2. Fault Phenomenon 2: Inability to perform linear travel → Fatigue fracture or insufficient elasticity of the rear reset spring, preventing the valve spool from returning to neutral.
3. Replacement Note: Must replace as a complete assembly (valve spool + spring set). Replacing the spring alone is not recommended; the valve rod and valve hole are precision-matched and ground components.
VI. Product Classification
- Original Factory New Parts: Produced by Sany/Hengli, complete assembly with spring, dimension tolerance matching the valve body.
- Aftermarket Replacement Parts: Domestic precision-machined valve spools, mainly used for cost reduction in repairs.
