Access Valve Core for Air Conditioner R22 R134 R410
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).
