Analysis of functional features
1.Precise temperature control, energy saving and consumption reduction
The oil circuit circulation ratio is dynamically adjusted through the paraffin temperature sensing element to keep the oil temperature stable in the golden range of 80°C±5°C. This not only reduces the heating energy consumption by 6-8%, but also avoids the emulsification of lubricating oil caused by the generation of condensed water.
2.Double protection to extend life
Low temperature protection: bypass the oil cooler during cold start to accelerate the oil temperature to the working point and reduce cylinder wear.
Overheat protection: fully open the cooling passage when the temperature is >105°C to prevent carbonization failure of the seal.
3.Modular quick-install design
The valve body and the temperature sensing element adopt a split structure (reference model 98603-15). There is no need to disassemble the oil pipeline when replacing, and the maintenance time is shortened to within 15 minutes.

Typical application scenarios
1.Variable frequency compressor: Balance oil temperature fluctuations under variable working conditions in l22-l290 vsd models.
2.Mobile air compressor station: Provide anti-vibration temperature control solutions for c20-c140 series engineering compressors (especially suitable for -30°c extremely cold environment).
3.Oil-free machine system: Control gearbox lubrication temperature in ultima two-stage oil-free screw machine.
4.Heat recovery unit: Stabilize oil temperature to above 80°c to ensure the quality of waste heat output.

Details make reliability
1.Temperature sensing element: Filled with aviation-grade paraffin (phase change accuracy ±0.5°C), life>100,000 cycles.
2.Flow optimization: The conical valve core design makes the oil flow pressure drop <0.2Bar, saving 3% energy compared with traditional ball valves.
3.Anti-misinstallation structure: Asymmetric interface to avoid reverse oil pipe installation during maintenance.
Authoritative supporting data
1.Energy efficiency improvement: In the actual test of Compair L55, the unit equipped with A10630675 saves 7.2% of electricity compared with the mechanical temperature control valve.
2.Life verification: After Taibri laboratory accelerated aging test (ISO 19973:2015), the valve body can withstand more than 5 million starts and stops.
3.Compatibility certification: Suitable for the following lubricants:
Renner R400 (mineral oil)
Shell Corena S4 P (synthetic hydrocarbon)
Total Azolla ZS 46 (ester oil)

FAQ
Q1 How to judge whether A10630675 needs to be replaced?
A1: Check immediately if the following symptoms occur:
The oil temperature exceeds 100°C and cooling is still not triggered (temperature sensing element failure);
The oil temperature rises for more than 20 minutes after cold start (the valve core is stuck in the cooling position).
Q2 Can it be mixed with other brands of temperature control valves?
A2: Mixing is strictly prohibited! Although Edmac 3004086622 is an equivalent product, the difference in spring preload may cause the oil temperature deviation to be ±8°C2.
Q3 Is debugging required after installation?
A3: Only three steps are required:
Start the compressor and run it without load for 10 minutes;
Use an infrared temperature measuring gun to detect the valve body outlet temperature;
Adjust the temperature sensing element preload nut when the temperature difference is greater than 5°C.
Note:Achieving greater energy efficiency through precise temperature control – this is not only the technical mission of the Compair Thermostatic valve A10630675, but also the cornerstone of reliable operation of your compression system.
