The valve core of the air - conditioner maintenance valve is a precision control component inside the maintenance port of the refrigeration system pipeline, equivalent to a "mini - valve" of the system. Its core functions are normal - state sealing and operational conduction.
Material and Performance Advantages
1.Main Material: Brass: Low cost and easy to process, suitable for R22 and R134a systems (working pressure ≤ 300psi);
2.Stainless Steel: High strength and strong corrosion resistance, designed specifically for R410A high-pressure systems (pressure resistance ≥ 500psi).
3.Sealing Components: NBR O-ring: Temperature resistance - 20℃~100℃, compatible with R22;
Types and Application Scenarios
1.Standard Schrader Valve Core (Mainstream in Automotive Air Conditioning)
Features: It has a thimble - trigger structure. The valve core is opened and conducted through a tool. It is widely used in the high - and low - pressure maintenance ports of automotive air conditioners.
Scenarios: Pressure detection of automotive air conditioners, refrigerant charging or recovery.
2.Straight - thread Valve Core (Commonly Used in Home/Commercial Air Conditioning)
Features: Threaded interface (such as M12×1.25), requires a special wrench for installation, and has strong sealing performance.
Scenarios: Connection pipes between indoor and outdoor units of split air conditioners, multi - connected systems, or maintenance ports of large chiller units.
3.Tamper-proof Valve Core (for New Equipment Only)
Features: Non-standard interface, requires special tools to open, preventing non-professionals from misoperation.
Scenarios: Commercial air conditioners or systems with high safety requirements (such as cold storage, precision air conditioners).
