1.5″ Stainless Steel Motorized Ball Valve Low Flow Resistance Auto Control
DN40 1.5-inch Electric Ball Valve – full port with low flow resistance, available in DC12/24V and AC110/220V, supports PLC automation control, suitable for HVAC, irrigation, and water treatment, with manual override.
Description
1. Core Function & Operating Principle
This 1 1/2″ stainless steel motorized ball valve is driven by an electric actuator for 90° on/off control, enabling automated pipeline flow isolation. The body features a full port design with no internal bore reduction, ensuring extremely low flow resistance—significantly reducing system pressure losses compared to solenoid valves, and making it well suited for continuous fluid transfer applications. The actuator is available in 2 wire motorized ball valve and 5 wire motorized ball valve wiring configurations, supporting passive feedback signal output for direct integration with building automation systems and smart agriculture PLC platforms.
2. Materials, Specifications & Technical Parameters
The valve body is offered in brass or 304/316 stainless steel, with EPDM/PTFE temperature‑resistant seals. Connection is via NPT female thread, with a standard bore of 1‑1/2″ (DN40), compatible with a wide range of industrial piping systems.

3. Industry Applications
This valve is ideal for HVAC motorized ball valve applications in heating/cooling circulation systems, smart agricultural irrigation, pure water equipment, small‑scale chemical process lines, and swimming pool water recirculation. It is suitable for both indoor equipment and outdoor exposed pipelines, with good resistance to light sediment fouling.
4. Real‑World Project Case – Central California Irrigation Farm
A large‑scale irrigation farm in Central California (4125 W Shaw Ave, Fresno, CA 93701) adopted this 1 1/2″ motorized ball valve across its entire zoning irrigation network. The farm utilizes a SCADA automation platform, where the valves are triggered by soil moisture sensors to automatically open/close branch lines. The full‑port low‑resistance design reduced pump load by 22%, delivering water and energy savings. After 18 months of continuous operation, no leakage or sticking issues have been reported, making it a standardized choice for smart irrigation systems in North America.
5. Procurement & Selection Advantages
Compared with solenoid valves or butterfly valves of the same size, this product offers a higher flow coefficient (Cv) and more stable remote automation control. A manual override feature is available for emergency manual operation during power outages. CE certification is provided, and we support custom voltage and wiring configurations for bulk orders, catering to the needs of overseas procurement projects.
