HS-R1234yf MANIFOLD GAUGE SET

Main features
1. Dual pressure gauge design:
The blue pressure gauge is usually used to measure the pressure on the low-pressure side, and the unit can be psi or bar.
The red pressure gauge is used to measure the pressure on the high-pressure side, and the unit can also be psi or bar.
The pressure gauge is also marked with a temperature scale, which can measure the temperature of the refrigerant at the same time.
2. Manual regulating valve:
The manual regulating valve is used to control the flow of refrigerant, thereby adjusting the pressure in the system.
The regulating valve usually has two handles, which control the flow on the high-pressure side and the low-pressure side respectively.
3. Connection interface:
Dual gauge valves usually have two interfaces, which are connected to the high-pressure side and the low-pressure side of the refrigeration system respectively.
The interface usually adopts standard threaded connection for easy installation and disassembly.
4. Safety device:
Some dual gauge valves are equipped with safety devices, such as pressure relief valves, to prevent damage caused by excessive system pressure.
5. Material:
Dual gauge valves are usually made of corrosion-resistant materials, such as brass or stainless steel, to adapt to different refrigerants and working environments.

1. Product Overview
Double-gauge valve is a commonly used tool in the field of refrigeration and air conditioning maintenance and installation, also known as manifold pressure gauge set. It uses two pressure gauges to measure the pressure on the high-pressure side and low-pressure side of the refrigeration system respectively, to assist technicians in judging the system operation status, charging refrigerant and other operations.
2. Component Function
Pressure gauge: Generally, the blue interface is connected to the low-pressure side to measure the suction pressure; the red interface is connected to the high-pressure side to measure the exhaust pressure. The pressure value (in units of psi, bar, MPa, etc.) is often marked on the dial, and some are also marked with the corresponding refrigerant temperature value, which is convenient for comparison and judgment of the system status.

Valve: There is a manually controlled needle valve inside, which controls the refrigerant flow, system vacuum and refrigerant charging by rotating the opening and closing degree of the valve.

Interface: There are multiple interfaces for connecting refrigerant cylinders, vacuum pumps, refrigeration systems, etc. to realize the pipeline connection between different equipment. Some double-gauge valves also have a sight glass in the middle to observe the flow state of the refrigerant.
3. Refrigerant compatibility
Different dual-meter valves are suitable for different refrigerants, such as the common R134a, R410A, R22, and new environmentally friendly refrigerants such as R1234yf. When using, please make sure that the dual-meter valve matches the refrigerant used in the system.
4. Advantages
Multi-function integration: It can complete multiple operations such as pressure measurement, vacuuming, and refrigerant filling, reducing the tools that need to be carried.
Accurate measurement: It can accurately measure the high and low pressure side pressures of the system, providing a basis for fault diagnosis and system debugging.
