Description
This smart irrigation butterfly valve combines a butterfly valve assembly with an ST-A2 solar-powered controller. It is an option for irrigation distributors and installation contractors specifying remotely operated shut-off points in commercial pipe networks. The selected valve body and connection type must match the site’s hydraulic and installation requirements.
Applications
- Remote opening and closing of irrigation pipe sections or zone inlets.
- Solar-powered operation where supplying mains electricity to each valve is inconvenient.
- Integrator-led pipe network upgrades requiring a specified actuator-and-valve assembly.
Application Illustration
The gallery also includes an edited detail view based on the reference product image. Use the confirmed datasheet and drawings for technical selection.
Smart Irrigation Butterfly Valve Selection
Start with the pipe connection and working conditions rather than the controller model alone. The available family includes UPVC wafer, metal wafer and metal flanged options. The product image shows one representative plastic-body assembly; it does not show every quoted variant. Check flange drilling, face-to-face length, disc clearance and gasket arrangement before selecting a replacement for an existing installation.
Technical Configuration
Listed values describe the available configuration. Confirm the current datasheet, dimensional drawing and itemized supply scope before ordering.
| Item | Configuration |
|---|---|

| Power | Solar panel + lithium battery |
| Communication | 4G configuration, subject to destination network compatibility |
| Listed actuator torque | ≥100 N·m; verify valve operating torque |
| Ambient / medium temperature | −20 to 60°C / 0 to 50°C |
| Feedback options | Pressure sensor, flow meter and external solar panel |
Installation and Integration Checks
- Provide maximum working pressure and differential pressure during opening/closing. Actuator torque must suit the selected disc, seal and operating conditions.
- Specify wetted materials and water quality. A metal valve body does not establish the seal’s compatibility with fertilizer or cleaning chemicals.
- Check the required closing sequence and pipeline surge conditions with the project designer.
- For overseas installations, confirm modem bands, SIM provisioning, platform language, account access and service charges.
Frequently Asked Questions
Does opening percentage provide a measured flow rate?
No. Disc angle, pressure and pipeline resistance determine flow. Volume-based irrigation requires appropriate measurement and supported control logic.
Is the pictured body supplied for every size?
No. Select the body and connection standard in the quotation. The representative image should not replace an approved dimensional drawing.
Are pressure and flow sensors included?
They are listed as options. Specify the required instruments, signal interfaces and mounting arrangements in the order.
