Just turn 1/4 circle to make the valve from full open to full closed.and it has rotation limitation.
Valve seat sealing with modified PTFE, quick on/off, seal-compensation function.
With two-way liquidity, large flow rate, small resistance;explosion-proof valve stem design.
High Quality and Quantity.
We are proud to present to you our 3 8 Refrigeration Ball Valve, a highly efficient ball valve designed for refrigeration systems. Its precision and superior performance make it the first choice in the industry.
Ⅰ. Main features and functions
High efficiency: The closed performance of the 3 8 Refrigeration Ball Valve is excellent, and the torque is low, which can make the fluid operation fast and accurate, thus greatly improving the cooling efficiency.
High quality material: Ball valve is made of corrosion-resistant metal, which makes it can be used in a variety of environments, and has a long life and strong durability.
Flow design: The internal design of the bearing ensures the full movement of the fluid, so that the transmission of the cooling fluid is more smooth.
Ⅱ. Application field
3 8 Refrigeration Ball Valve is suitable for a variety of refrigeration systems, including refrigerators, air conditioning systems, industrial cooling equipment, etc. Its use can not only improve the freezing efficiency, but also help save power consumption and improve equipment performance.

Independent development & One integrated mass
◆ Each high temperature weld may damage the inner core of the valve,however Hengsen developed a new modified process. It is to reduce a weld at the junction of copper pipe,which makes valves more immersible,safer and more beautiful.
Welding technology-high frequency welding
◆ Since the current is highly concentrated in the weld area, it heats up quickly on a small area and is not easy to be oxidize to ensure a good organization and performance of the weld.
◆ The welding surface is more uniform, beautiful and environmental friendly.
Easier operation convenient installation
◆ Only need to turn 1/4 round to open completely from closed.
◆ With limit switch either full open or full closed.
Unimpeded access design
◆ The pipe is unimpeded when the valve is open to connect the pipe.
◆ Valve seat fixing device can install on the stand to significantly reduce pipe virbration.

Technical Data
◆ Applicable medium:R22、R134a、R407C、R410a etc.
◆ Applicable medium temperature:-30℃-+120℃.
◆ Maximum working pressure:4.2MPa.
◆ Applicable environment temperature:-20℃-+60℃.
The 3 8 Ball Valve is easy to install and use, making maintenance of your cooling system simple and convenient.Possible safety issues in the refrigeration system have been fully considered during the development process, and our valves have an overpressure protection function to ensure that it can operate safely and reliably under any circumstances.
To sum up, the 3 8 Ball Valve achieves its goal of being efficient, durable and user-friendly, while also taking into account all possible safety concerns. It is a beautifully designed, powerful and easy to use device that is ideal for your refrigeration system. Please feel free to contact us if you have any questions or needs.
