Aluminum hand lever valve is a type of manual valve used to control the flow of fluids or gases in a pipeline. It consists of a valve body made of aluminum, which houses an internal mechanism that opens or closes a passage for the flow of fluid or gas. The valve is operated manually by a lever or handle attached to the valve body. When the lever is moved, the internal mechanism either allows or blocks the flow of fluid or gas through the valve. Aluminum hand lever valves are commonly used in a range of industries, including oil and gas, chemical processing, and water treatment. They are known for their durability, corrosion resistance, and lightweight design. Aluminum is also a good conductor of heat, which makes these valves suitable for high-temperature applications.
