Analysis of the Inch and a Half Ball Valve

A inch and a half ball valve, that is a 1-1/2” ball valve refers to a ball valve with a pipeline diameter of 1and 1/2 inches, which is commonly used in household water pipes and air conditioners systems.

I. The size of the 1-1/2” ball valve

The 1-1/2” ball valve, actually means that the pipeline diameter of the ball valve is 1and 1/2 inches. The inch is an imperial unit of length, and “1 and 1/2″ is a commonly used way of expression, indicating 1 inch plus 1/2 inch, that is, 1.5 inches. Therefore, the diameter of the 1-1/2” ball valve is approximately 38.1 millimeters. And 1” equals to DN25; 1-1/2” equals to DN40; 2″ equals to DN50.

II. The application of the 1-1/2” ball valve

Because the size of the 1-1/2” ball valve is moderate, it is widely used in many pipeline systems. In household, this specification of ball valve is often used to connect equipment such as water pipes, water heaters, and air conditioners. In the industrial field, it may also be used in some pipeline systems with smaller diameters.

III. How to select a suitable 1-1/2” ball valve

When selecting a 1-1/2” ball valve, in addition to paying attention to its size, the following points also need to be noted:

• Material selection: the material of the ball valve directly affects its service life and performance. Generally speaking, 1 and 1/2 inch stainless steel ball valve and brass ball valves have good corrosion resistance and durability, making them suitable for long-term use.
• Valve type: select the appropriate valve type according to the usage requirements. For example, a manual ball valve is easy to operate and is suitable for household environments; electric or pneumatic ball valves are suitable for scenarios that require automated control.
• Pressure and temperature range: ensure that the selected ball valve can withstand the pressure and temperature range in the pipeline system to ensure its normal operation.

IV. Preautions for installation and use

When installing and using a 1-1/2” ball valve, the following points need to be noted:

• Ensure the pipeline system is clean: before installation, the impurities and dirt inside the pipeline should be cleaned to avoid damage to the ball valve.
• Correct installation direction: according to the identification and instructions of the ball valve, ensure the correct installation direction. Generally speaking, the handle or operating rod of the ball valve should be easy to operate.
• Regular inspection and maintenance: regularly inspect the ball valve to ensure its good sealing performance and operability. If problems such as leakage or difficult operation are found, they should be dealt with timely.

In conclusion, the 1-1/2” ball valve is a common pipeline fitting specification, which is widely used in both household and industrial fields. By understanding its size meaning, application scenarios, and the precautions for selection, installation, and use, we can better select and use this ball valve to ensure the normal operation of the pipeline system.
