SANHUA CHARGE VALVE (TCJ series)

Sanhua TCJ Series: Key Selling Points (KSPs)

Advantage: Captures even microscopic metallic debris during the initial system commissioning and throughout its life.
Benefit: Acts as “insurance” for the most expensive parts of the system. By preventing a $5 strainer from clogging a $200 expansion valve or a $1,000 compressor, it dramatically reduces warranty claims and service call-outs.

Advantage: Uses an optimized stainless steel mesh with a high open-area ratio.
Benefit: Ensures that while the refrigerant is being cleaned, the system efficiency is not compromised. It provides effective filtration without causing the significant pressure drops that lead to reduced cooling capacity.

Advantage: The internal mesh is made of high-grade stainless steel.
Benefit: Unlike lower-quality filters that can corrode or break apart over time, the TCJ mesh remains intact, ensuring that the filter itself doesn’t become a source of contamination in the system.

Advantage: Slim, copper-body design.
Benefit: Extremely easy to install in tight spaces, such as inside the outdoor unit cabinet of an AC or within the small mechanical compartments of commercial refrigerators.

Category: CHARGE VALVE Brand: Sanhua

Function: Filters out solid contaminants from the refrigerant to prevent clogging of small orifices and mechanical wear of moving parts.
Filtering Element: Uses a high-quality Stainless Steel Wire Mesh.
- Mesh Density: Available in various densities (e.g., 100 mesh or 150 mesh) to balance filtration fine-ness with pressure drop.
Body Material: Primarily Copper (for smaller/straight-way versions) or Brass, allowing for easy brazing into the system piping.
Design: Usually a Straight-way (pencil-type) or Y-type design for easy integration into liquid or suction lines.
Applications:
- Protecting Expansion Valves (TXVs/EEVs).
- Protecting Capillary Tubes in small appliances.
- Suction line protection for compressors.

Refrigerant Compatibility: Applicable for all common HCFC, HFC, and HFO refrigerants (R22, R134a, R404A, R407C, R410A, R32, R1234yf, etc.).
Max. Operating Pressure (PS): Typically rated up to $4.5\text{ MPa}$ ( $45\text{ bar}$ ).
Temperature Range ( $T_S$ ): $-30^{\circ}\text{C}$ to $+120^{\circ}\text{C}$ .
Connections: Available with ODF (Solder) connections in various sizes (e.g., $1/4''$ , $3/8''$ , $1/2''$ , etc.).
