After understanding the structure and working principle of electric threaded ball valves - and exploring their advantages and applications - the next step is learning how to select, install, and maintain them properly.
Proper selection and maintenance are key to extending service life and ensuring safe, efficient performance of your valve system. In this guide, we'll walk you through the main selection criteria, installation precautions, and maintenance practices to help you get the most from your electric threaded ball valve setup.
Selecting the right electric threaded ball valve involves evaluating both mechanical and electrical parameters.
The following table summarizes the main considerations:
| Selection Item | Considerations |
| Medium Characteristics | Corrosiveness, temperature, viscosity, and whether the fluid contains particles or impurities. |
| Pressure Rating | Choose the valve pressure class according to system pressure (e.g. PN16, PN40, Class 150). |
| Bore Size | Match valve size to the pipeline diameter to ensure the required flow capacity. |
| Connection Type | Confirm thread standard (NPT, BSPP, BSPT, etc.) and dimensions. |
| Power Supply | Match actuator voltage (AC/DC), frequency, and power rating. |
| Control Signal | Select from on/off type, modulating type, or fieldbus communication type. |
| Protection Grade | Choose a suitable IP rating (e.g. IP65, IP67) based on installation environment. |
| Material Compatibility | Valve body, ball, and seat materials must be compatible with the medium and operating conditions. |
Tip:
For ball valves, body and seat materials are crucial to long-term durability and sealing performance.

Proper installation ensures leak-free performance and prevents premature wear of valve components.
Here are key points to follow:
· Clean the pipeline before installation to remove welding residues or impurities that could damage the valve seat.
· Check the flow direction - if there's a directional mark on the valve body, make sure to follow it during installation.
· Leave sufficient space around the valve for maintenance or actuator removal.
· Avoid excessive piping stress that could distort the valve body.
· Ensure correct wiring- follow electrical standards and apply waterproof sealing where necessary.
Proper installation not only guarantees sealing reliability but also helps protect the actuator and valve seat from early damage.
Even with high-quality components, regular inspection is essential for reliable operation:
· Periodically check actuator operation and response time.
· Inspect for any external leakage, unusual noise, or vibration.
· Test valve opening and closing performance at scheduled intervals.
· For valves idle for long periods, operate them periodically to prevent sticking.
· Replace seals and soft parts according to wear condition or planned maintenance cycles.
Routine maintenance helps extend service life and ensures the system continues to operate safely and efficiently
