Understanding the pressure and temperature requirements of your application. It is crucial to choose a suitable electric globe valve. Valves receive a rating for a specific range of pressure and temperature. It exceeding these limits can result in valve failure or compromised performance. Choose a valve that can withstand the highest pressure and temperature levels.

3.Flow Characteristics

Consider the flow characteristics of your application. It requires on-off control or precise throttling. Globe valves are known for their excellent throttling capabilities. It allows for accurate regulation of flow rates. Other valve types, such as ball valves or butterfly valves. It may be more suitable for simple on-off applications. Determine your specific flow control needs before making a decision.

4.Size and Connection Type

Selecting the right valve size is crucial. It ensures proper flow rates and system compatibility. Valves come in various sizes, ranging from a few inches to several feet in diameter. Consider the connection type, such as flanged, threaded, or welded. It ensures seamless integration into your existing piping system.

5. Actuation Method: Electric

When it comes to electric-actuated globe valves, the actuation method is critical. Electric actuators or motors power electric globe valves. It provides automated control and eliminates the need for manual operation. These valves are very preferred for applications. It needs remote control, precision, and reliability.

Preparations before Installing the Electric Globe Valve

2. Select the Right Valve

• Choosing the right electric globe valve is crucial. It achieves optimal performance and longevity. Consider the following factors when selecting a valve:
• There are different types of electric globe valves. It includes straight patterns, angle patterns, and three-way valves. Choose the type that best suits your application.
• Ensure that the valve materials are compatible with the fluid and environmental conditions. It prevents corrosion and damage.
• Choose a device supplying the necessary torque or force to operate the valve well.
• Calculate the required valve size based on the flow rate, pressure drop, and pipe diameter.

3.Prepare the Installation Area

• Before installing the electric globe valve, must prepare the installation area well. Follow these steps to ensure a suitable environment for the valve.
• Remove any debris, dirt, or obstructions that may interfere with the valve’s operation.
• Ensure that the mounting surface can support the weight of the valve. It also supports actuators without any structural issues.
