Next-generation valve that reduces operational variation and improves sealing performance.
This service valve adopts a new joint method using a compression fitting instead of a flare nut, which is prone to variations in work. The tightening process is completed when the gap between the nut and the body is eliminated, allowing anyone to easily perform the task. After the work is completed, checking for gaps ensures that the work was done correctly. Additionally, there is no need for lap flare processing during connection, which helps to reduce work deficiencies and variations, thereby eliminating refrigerant leaks caused by construction errors.

basic information
1. Reliable Metal Compression Seal As the tightening nut is tightened, the metal ferrule compresses against the outer circumference of the copper pipe to create a seal. The compression point with the copper pipe is large, providing stable sealing performance. 2. Permanent Joint Structure The outer circumference of the fixed nut is cylindrical, making it difficult to loosen a joint once it has been tightened. We aim to achieve a joint that meets European standards for permanent joints. 3. No Torque Management Required During Connection The connection is complete once the tightening nut is tightened and there is no gap between the fixed nut and the valve. There is no need to manage torque, allowing anyone to connect easily and reliably. 4. No Need for Flare Processing There is no need for flare processing during installation. This reduces concerns about refrigerant leaks due to variations in work or mistakes. 5. Temporary Fixing Function for Copper Pipe After inserting the copper pipe, it can be temporarily fixed by hand-tightening the tightening nut. There is no worry about the piping coming loose until the installation is complete, and there is no need for marking, etc. 6. Ferrule Loss Prevention The ferrule is assembled to the fixed nut to prevent loss. Therefore, there is no concern about damaging or losing the ferrule.
