Compair Thermostatic Valve A11072374A11072374

Tips： This model belongs to the Compair temperature control valve family (such as A11175274, A11513574, etc.), adopts a modular design, and supports quick replacement.

The Compair Thermostatic Valve A11072374 is a key temperature control component designed specifically for Compair screw air compressors. It regulates lubricating oil flow, ensuring the oil temperature quickly reaches and stabilizes within the optimal operating range. This valve, typically installed between the oil separator, cooler, and compressor head, is made of copper and bypasses high-temperature oil to the cooler, preventing premature condensation and ensuring efficient compressor operation and long life. As an equivalent replacement for the original manufacturer, it is suitable for a variety of industrial scenarios and requires professional installation to ensure compatibility.

1.Precise temperature control to ensure energy efficiency
Compair Thermostatic valve automatically adjusts the bypass oil opening by sensing oil temperature changes through paraffin thermistors. The bypass is closed during low-temperature startup to accelerate the oil temperature rise; the bypass is fully opened during high-temperature operation to prevent oil oxidation and reduce energy consumption by more than 12%.
2.Anti-wear and long-lasting design
The copper valve body is equipped with a hardened stainless steel spring to withstand high-frequency start-stop impacts. The measured life span exceeds 15,000 hours, which is 30% longer than that of ordinary cast steel valve bodies.
3.Wide environmental adaptability
Supports cold start in an extremely cold environment of -10°C, and the seal does not fail under high-temperature conditions of 120°C, adapting to the operating requirements of compressors in different climate regions around the world.

Compair thermostatic valve a11072374 is the "temperature gatekeeper" of industrial compression systems. Typical scenarios include:
1.Manufacturing: Pneumatic systems of injection molding machines and cnc machine tools to prevent condensed water from causing component corrosion.
2.Energy mining: Screw compressors of oilfield drilling rigs to ensure the cleanliness of the oil circuit in high-temperature dusty environments.
3.Food and medicine: Oil-free compressors are equipped with oil cooling circuits to meet ISO 8573-1 class 0 pollution-free requirements.
4.Transportation: High-speed rail/ship brake system compressors to avoid response delays caused by low-temperature oil viscosity.

1. Thermal Response Core Technology
The valve core is filled with high-purity paraffin (phase change material), which expands and pushes the piston when the temperature reaches 70°C. The valve opening response time is less than 3 seconds, and the accuracy is 40% higher than that of mechanical temperature control valves.
2.Anti-stuck structure
The valve stem adopts chrome plating and polishing process, the friction coefficient is ≤0.08, and the oil and dirt adhesion rate is reduced by 60%. The unique conical return spring design eliminates the risk of impurities blocking.
3.Compatibility design
The interface conforms to the Compair G1/2" standard, and an adapter kit (optional) is also provided, which can be adapted to Atlas Copco GA series and Ingersoll Rand IRN models.

1.Performance benchmarked against OEM: Third-party testing shows that its flow curve coincides with the original Compair valve by more than 98% (test standard: ISO 1217).
2.Supply chain traceability: Each valve is laser engraved with a unique serial number, which supports the original factory database verification (official website verification portal: taibri.com/verify).
3.Industry application performance: Purchased by compressor service providers in 40+ countries around the world, including leading channel providers such as NPS Compressed Air Solutions.

We understand the core demands of industrial spare parts procurement: zero-error delivery and worry-free after-sales service. To this end, we provide:
1.Precise matching: Provide compressor serial number, free verification of model compatibility (24-hour response).
2.Global logistics: DHL/FedEx express line, 4-6 working days to the United States, support customs clearance agency.
3.Technical support: Free access to installation videos and technical manuals (including torque parameters, leak detection steps).
4.Warranty upgrade: 2-year extended warranty (industry standard 1 year), faulty parts can be replaced directly without return.

Q1: Can it replace A11175274 or A11513574?
A1: Yes. A11072374 and A11175274 are upgraded models of the same series, with the same interface size, but improved temperature control accuracy (±3°C → ±1.5°C). The spring preload matching with A11513574 needs to be confirmed.
Q2: Is the valve body resistant to synthetic ester oil?
A2: Fluororubber seals are compatible with PAO/ester full synthetic oil (oil resistance grade: ISO 6072 Class 3). However, avoid using acidic cleaning agents containing ester groups.
Q3: The oil temperature still fluctuates greatly after installation. How to troubleshoot?
A3: Operate in three steps:
① Check the installation direction of the valve body (the arrow must point to the oil cooler inlet);
② Use an infrared thermometer to monitor the valve shell temperature. If the valve does not open at >80°C, replace it;
③ When the oil filter pressure difference is >2 bar, replace the filter element first.
