Product Features

 

1.Precise temperature control
Adopting wax-type temperature sensing elements imported from Germany, the response speed of Compair thermostatic valve replacement is 30% faster than that of ordinary valves, ensuring that the compressor lubricating oil is always in the optimal operating temperature range.
2.Double seal design
The A11203274 model adopts a stepped seal structure at the valve stem, which still maintains zero leakage after 20,000 opening and closing tests, significantly extending the maintenance cycle.
3.Corrosion resistance upgrade
The inner cavity of the valve body is specially nickel-plated to resist the corrosion of sulfur-containing lubricating oil, solving the problem of early failure of traditional Compair thermostatic valve replacement under harsh working conditions.

Product Details

 

1.Precision Casting Process
Each A11203274 valve body is formed by lost wax casting, and the inner surface roughness is controlled within Ra0.8μm, which is 50% smoother than the industry standard Ra1.6μm.
2.Modular Design
This Compair thermostatic valve replacement adopts a quick-release structure. When replacing, there is no need to empty the entire cooling system, saving 90% maintenance time.
3.Anti-misinstallation slot
The unique asymmetric positioning pin design ensures that the A11203274 will not be reversed during installation, avoiding equipment damage caused by human operating errors.

FAQ

 

Q: How do I determine if the A11203274 thermostatic valve needs to be replaced?
A: Inspection is recommended when the lubricating oil temperature fluctuates by more than ±5°C, the compressor frequently issues high temperature alarms, or the energy consumption increases by 15%.
Q: Does a non-original Compair thermostatic valve replacement affect the warranty?
A: Using third-party spare parts that meet the specifications will invalidate the warranty.
Q: What are the improvements of A11203274 over the old A11203273?
A: The new model has an anti-vibration bracket interface, which increases the life in a vibration environment by 40%, and the flow coefficient by 12%.
