New Copper Access Valve Filter Drier Brass Cover for Refrigeration

As a key component of the copper maintenance valve filter drier, the brass cover mainly undertakes the functions of sealing, connection and maintenance operation, and is a core component to ensure the stability of the refrigeration system and the convenience of maintenance.

Key features

1.High-strength Sealing: Made of brass (copper-zinc alloy), it is precisely processed to form a smooth sealing surface. When combined with the copper body, it achieves zero leakage in high-pressure environments, preventing refrigerant from escaping or outside air from infiltrating.
 

2.Integrated Maintenance Interface: The interface design complies with industry-wide common standards and is compatible with mainstream maintenance tools, improving maintenance efficiency.
 

3.Corrosion and Oxidation Resistance:The surface of the brass is nickel-plated or passivated. Its corrosion resistance is superior to that of ordinary copper materials. It can resist the long-term erosion of refrigerants (such as fluorine-containing compounds) and lubricating oil, extending the service life of components.
 

4.Convenient Installation and Maintenance:It adopts threaded connections (such as straight pipe threads or tapered pipe threads), which can be quickly tightened and fixed to the copper body. Welding is not required during installation, reducing the risk of high-temperature operations. It supports individual disassembly for cleaning or replacement. When the maintenance interface is worn or the seal fails, the brass cover can be directly replaced without replacing the entire dryer, reducing maintenance costs.

Application Scenarios:

1.Household/Commercial Air Conditioners: The drying filter installed between the outdoor unit condenser and the indoor unit expansion valve facilitates regular maintenance.
 

2.Cold Storage/Cold Chain Equipment: It provides reliable sealing in high-pressure refrigeration pipelines and supports frequent maintenance operations (such as pressure monitoring of cold chain transportation equipment).
 

3.Industrial Refrigeration Systems: It is suitable for equipment such as large chillers and screw compressors, meeting the sealing and maintenance requirements under high-load working conditions.
