We’re happy to help you find the best option for your application.
✅ Military-grade pressure relief technology: Utilizes a dual-spring redundant design with a response speed of <0.1 seconds, precisely controlling pressure fluctuations.
✅ Superior environmental adaptability: Stable performance in extreme temperatures ranging from -40℃ to +120℃, eliminating refrigerant leakage.
✅ Intelligent diagnostic function (optional): Real-time monitoring of system pressure, automatic alarm for abnormalities.
✅ Original factory precise matching: Customized specifically for the XE2000 air conditioning system, 100% compatible with the original vehicle interface.
• Opening pressure: 3.8MPa±0.2MPa
• Closing pressure: 3.2MPa±0.2MPa
• Maximum flow rate: 25L/min
• Valve body material: 316 stainless steel + special sealing ring
• Applicable refrigerant: R134a/R1234yf
✔ Completely solves the risk of high-pressure pipe bursts in mining equipment air conditioning systems.
✔ Prevent compressor overload damage (repair cost savings of ¥8,000+)
✔ Eliminate seal failure caused by extreme temperature differences
• ISO 13016 automotive air conditioning certified
• 5-year/10,000-hour warranty
• Pressure-flow characteristic curve included with each batch
▸ Overpressure protection on the high-pressure side of the compressor
▸ Air conditioning system overhaul and maintenance
▸ Equipment modification in high-temperature mining areas
⚠ Using a substandard pressure relief valve may result in:
• Compressor damage (repair cost: ¥12,000+)
• Refrigerant leakage of up to 30% annually
• A 60% decrease in cab cooling efficiency
“It is recommended to perform a pressure test every 2 years. Intelligent pressure relief valves can prevent 90% of air conditioning system failures.”
