R410A R22 Liquid Safety Adapter Flow Control Ball Valve Refrigerant Charging Valve for Air Conditioner

R410A R22 Liquid Safety Adapter Flow Control Ball Valve Refrigerant Charging Valve for Air Conditioner

A refrigerant charging and control tool specifically designed for air - conditioning systems. It is suitable for refrigerants such as R410A, R22. The main functions include:

1.Safe Charging: Connect the refrigerant cylinder to the air - conditioning system, control the flow direction and flow rate of liquid refrigerant, and avoid high - pressure leakage or misoperation.

2.Flow Regulation: Precisely control the refrigerant flow rate through the ball valve, ensure accurate charging amount, and improve the system operation efficiency.

3.System Protection: The built - in safety structure prevents the reverse flow of refrigerant, avoiding system contamination or damage.

Working principle:

1.Connection: Connect one end of the adapter to the refrigerant cylinder, and the other end to the low/high pressure port of the air - conditioning system through a hose.

2.Switch control: Rotate the ball valve handle to open the passage, and the liquid refrigerant flows into the system through the adapter; when closed, the flow path is cut off to prevent leakage.

3.Flow regulation: Change the valve opening through the handle or fine - tuning knob to control the refrigerant flow rate (such as rapid filling or slow replenishment).

Application

First-time refrigerant charging for new units.
Refrigerant replenishment after system fluorine leakage (vacuuming with a vacuum pump is required).

Refrigerant replenishment for large systems such as cold storage and chiller units.

Some models are compatible with automotive air conditioning interfaces (such as R134a systems), but attention should be paid to the matching of refrigerant types.
