A charging valve is a special valve used in refrigeration systems that allows technicians to charge or discharge refrigerant into or out of the system. This valve is essential for installing, maintaining, and repairing refrigeration equipment such as air conditioners, refrigerators, cold storage, etc.
Here are some typical features and functions of charging valves:
Two-way flow: Charging valves allow refrigerant to flow in both directions, either into or out of the system.
Precise control: With charging valves, technicians can precisely control the amount of refrigerant charged, ensuring optimal performance of the system.
Safety features: Charging valves are often designed with safety features such as overpressure protection to prevent the system from over-pressurizing.
Durability: Charging valves are often made of durable materials such as brass and stainless steel to ensure long-term use.
Multiple connection options: Charging valves can be designed to connect to different types of refrigeration systems, including threaded connections, flange connections, etc.
Easy to operate: Charging valves are often designed to be easy to operate, allowing technicians to quickly charge or discharge refrigerant.
Easy to maintain: Charging valves are designed to be easy to clean and maintain to maintain their performance.

Features:
Copper valve body: The valve body may be made of copper, which has good corrosion and wear resistance.
Brass connector: The connector may be made of brass, which has good pressure resistance.
Different lengths: Different models of filling valves may have different lengths to suit different installation needs.
