Sullair Thermostatc Valve Kit 02250142-940

Tips:Sullair temperature control valve kit 02250142-940 - original factory standard, reliable performance

The 02250142-940 temperature control valve kit is designed specifically for Sullair screw air compressors. Made of stainless steel, it controls the valve core opening by utilizing the thermal expansion and contraction of a paraffin/brass mixture. As the oil temperature fluctuates, the valve automatically adjusts the amount of oil flowing through the oil cooler, ensuring a mixed flow of hot and cold oil before entering the airend. This precisely maintains the compressor exhaust temperature (typically set at 76°C), ensuring efficient and stable operation. This valve core offers a long lifespan, is wear-resistant, and can operate thousands of times. Suitable for models such as the LS20S, it is a reliable alternative to the original spare part (replacement number: 02250142940).

1.Precise temperature control, energy saving and consumption reduction

By dynamically adjusting the oil flow, the air compressor is kept running at a constant temperature, avoiding low-temperature startup wear and high-temperature shutdown, and reducing energy consumption by 12%.

2.Double-effect seal anti-deterioration

The metal bellows + fluororubber double seal structure is used to withstand oil corrosion and high-pressure impact, and the service life is 2 times longer than that of ordinary valve bodies.

3.Ready-to-install and no adjustment

Pre-calibration design, replacing the original valve only requires 4 steps (remove the old valve → clean the interface → install the new part → power on the test), and the maintenance efficiency is increased by 50%.

"The 02250142-940 kit perfectly matches our Sullair 75kW unit. After replacement, the oil temperature fluctuation is reduced from ±15℃ to ±3℃!" --Buyer's technical evaluation

02250142-940 Sullair thermostatic valve kit has been successfully applied to the following industrial scenarios:

1.Manufacturing: air compressor unit of automobile factory spraying line (to prevent low temperature sludge condensation).

2.Energy mining: air compressor system for oil field drilling rig (resistant to sand, dust and vibration environment).

3.Food and medicine: air source guarantee for aseptic filling equipment (in compliance with ISO 8573-1 oil-free air standard).

1.Structural design highlights;

Three-way diversion technology: through the independent oil bypass design, the oil temperature rise is accelerated at low temperatures and the cooling cycle is strengthened at high temperatures.

Modular components: the valve body, sensor, and spring can be replaced separately to reduce the subsequent maintenance costs.

2.Process quality;

Copper content ≥99.8% Copper content ≥99.6%

Terminal case: A Chinese wind power company purchased 320 sets in succession, and the failure rate dropped from 11% to 0.9% (data in 2024).

1.Quick response: 24-hour online technical support (WhatsApp/email), providing installation videos and fault code interpretation.

2.Flexible delivery: Support DHL/FEDEX expedited logistics, global delivery within 7-15 days (direct delivery from China warehouse).

3.Worry-free after-sales: 30-day unconditional return and exchange, free replacement within 1 year for non-human damage.

Q1: Is it compatible with non-Sullair brand air compressors?

A: It is only recommended for Sullair equipment! Third-party equipment needs to provide interface dimensions and oil circuit diagrams, and the technical support team can evaluate the compatibility.

Q2: How to identify genuine products?

A: The genuine 02250142-940 valve body has a clear laser engraved number without burrs, and comes with an ISO 9000 certificate and anti-counterfeiting QR code.

Q3: Is there a discount for large purchases?

A: Exclusive discounts for orders of ≥50 sets! Please contact customer service to obtain a step-by-step quotation (supports T/T and Western Union payment)
