3/8 Inch 3 Way Motorised Brass Ball Valve Mini Series – ABVM03B3
The ABVM03B3 is a compact 3/8 inch motorised brass ball valve designed for automatic diverting, mixing and changeover of potable water and compatible fluids.
Available with either L-Port or T-Port flow configurations, the valve provides flexible automatic flow control for building services, process control, OEM equipment and water management systems. The T-Port version offers four selectable flow configurations, making it suitable for a wide range of diverting and mixing duties.
Manufactured from high-quality CW617N brass with WRAS approved PTFE and EPDM seals, the valve combines reliable bubble-tight shut-off with low power motorised operation and IP67 environmental protection. Power Open/Close and Failsafe Return versions are available to suit virtually any control system.

GREEN – Control wire
Power applied to the GREEN wire moves the valve to the powered position.
Removing power from the GREEN wire returns the valve to its start position.
Failsafe Return (2 Wire)
Power ON drives the valve to its operating position.
Power OFF automatically returns the valve to its start position using the internal reserve power system.
Requires approximately 30 seconds of applied power to fully recharge the reserve capacitors.
