OEM 813501010 The XCMG Expansion Valve (813501010) is a genuine OEM precision metering device engineered specifically for reliable refrigerant flow control in the HVAC systems of XCMG articulated dump trucks. This precision‑manufactured expansion valve, identified by part number 813501010, ensures consistent superheat regulation, optimal evaporator performance, and exceptional durability in the most demanding mining, quarrying, and heavy construction environments worldwide.
Manufactured with high‑grade brass or aluminium bodies, precision‑orificed seats, and robust sensing elements, the 813501010 expansion valve delivers accurate refrigerant metering, excellent response to thermal load changes, and exceptional reliability across a wide temperature and pressure range. Its precision‑engineered dimensions and connection fittings guarantee a perfect, drop‑in fit without modification.
The 813501010 expansion valve features a thermostatic sensing bulb that modulates the valve opening based on evaporator outlet temperature, a corrosion‑resistant body that withstands refrigerant and moisture exposure, and precision‑machined orifices that ensure stable superheat control, making it an essential component for maintaining cooling capacity, preventing compressor slugging, and maximising cabin comfort while reducing fuel consumption in your ADT fleet.
The 813501010 Expansion Valve is manufactured with a precision‑machined orifice, a robust thermostatic sensing element, and a corrosion‑resistant body, ensuring accurate superheat control, stable evaporator performance, and predictable cooling capacity across every unit.
Its thermostatic expansion mechanism modulates the refrigerant flow rate based on the temperature and pressure of the refrigerant exiting the evaporator, maintaining the optimal superheat to maximise heat absorption and prevent liquid refrigerant from returning to the compressor.
The precision‑ground valve seat and needle assembly provide excellent throttling characteristics, ensuring smooth modulation and stable operation across a wide range of thermal loads and engine speeds.
The remote sensing bulb with capillary tube is carefully positioned on the evaporator outlet line, providing fast and accurate temperature feedback that ensures the valve responds rapidly to changing cabin heat loads.
In demanding applications such as open‑pit mines, aggregate quarries, and heavy construction sites, the 813501010 delivers reliable, long‑lasting expansion valve performance for your ADT’s cabin cooling and dehumidification systems.
The 813501010 expansion valve is produced using advanced CNC machining, precision assembly, and charge calibration processes, achieving tight tolerances on all critical parameters, including orifice diameter, superheat spring rate, and sensing bulb charge quantity.
The orifice is laser‑drilled or broached to exacting diameter tolerances, ensuring consistent refrigerant flow characteristics and stable superheat control across the full capacity range.
The sensing bulb is filled with a specific refrigerant charge (cross‑charge or liquid charge) that provides the necessary pressure‑temperature relationship to achieve the desired superheat characteristic.
The diaphragm and push‑rod assembly are manufactured from corrosion‑resistant alloys, ensuring responsive movement and long‑term sealing integrity without sticking or hysteresis.
After production, each valve undergoes 100% functional testing, including superheat calibration, leak testing (helium or refrigerant), and flow capacity verification to ensure it meets the required specifications.
Sample units from each production batch are subjected to cycling endurance, thermal shock, and corrosion testing (salt spray) to validate long‑term durability and performance.
Articulated dump trucks depend on precisely controlled refrigerant flow to maintain evaporator temperature and prevent compressor damage. The expansion valve is the key metering device that ensures liquid refrigerant is vapourised at the correct rate within the evaporator.
The 813501010 expansion valve regulates the flow of refrigerant into the evaporator based on superheat, ensuring that the evaporator is fully utilised for cooling without allowing liquid refrigerant to reach the compressor (which can cause slugging and severe damage).
A substandard or stuck expansion valve can lead to poor cooling, evaporator freeze‑up, or compressor failure — risks that are eliminated by using genuine XCMG expansion valves.
Field data from mining operations shows that ADTs equipped with genuine XCMG expansion valves experience 35% fewer HVAC cooling‑related complaints and a 20% reduction in compressor replacement costs, directly improving machine availability and operating costs.
The valve’s accurate superheat control ensures that the compressor operates within safe temperature limits, extending its service life and reducing the risk of refrigerant oil breakdown.
Regular inspection of expansion valves for signs of corrosion, bulb damage, or erratic performance is recommended; any compromised valves should be replaced promptly with genuine 813501010 components.
The 813501010 expansion valve is manufactured from high‑grade materials that provide an exceptional combination of thermal conductivity, corrosion resistance, and mechanical strength, ensuring reliable performance with modern refrigerants and lubricants.
The brass or aluminium body is treated with a conversion coating or anodised to prevent galvanic corrosion and pitting, ensuring long‑term integrity even in high‑humidity environments.
The internal components (needle, seat, diaphragm) are made from stainless steel or specialised alloys that resist wear and chemical attack from refrigerant and oil mixtures.
The sensing bulb and capillary tube are protected by a corrugated or braided sleeve to resist abrasion and mechanical damage during installation and operation.
With proper installation and routine maintenance, the 813501010 expansion valve can provide reliable service for the entire lifespan of the ADT, reducing the need for premature replacements.

The 813501010 expansion valve is designed for straightforward installation using standard refrigeration tools, minimising downtime and labour costs during routine servicing or component replacement.
Before installation, carefully inspect the new valve for any signs of damage, bent capillary tube, or deformed fittings that may have occurred during storage or transport, and ensure that the system is properly recovered and evacuated.
Position the valve in the liquid line before the evaporator, ensuring correct flow direction (indicated by an arrow on the body), and securely connect the inlet and outlet fittings using the appropriate torque to prevent leaks.
Mount the sensing bulb firmly on the evaporator outlet line, using the supplied clamp and insulation tape to ensure good thermal contact and protection from ambient heat.
After installation, evacuate and recharge the system with the correct refrigerant and oil, and verify superheat adjustment using manifold gauges and a thermometer to ensure optimal performance.
During routine maintenance, inspect the valve and sensing bulb for signs of corrosion, leakage, or insulation damage, and replace it if any degradation or performance loss is detected.
