Description
1 Inch 3 Way Motorised Brass Ball Valve Mini Series – ABVM08B3
The ABVM08B3 is a compact 1 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 HVAC systems, Building Management Systems (BMS), water treatment, renewable energy and industrial process applications. The T-Port version offers four selectable flow configurations, making it ideal for mixing, diverting and changeover duties where higher flow capacity is required.
Manufactured from high-quality brass with WRAS approved PTFE and EPDM seals, the valve combines reliable bubble-tight shut-off with a low power IP67 motor actuator. Power Open/Close and Failsafe Return versions are available to suit virtually any control system.

Visual position indication included.
Control Options
Power Open / Power Close (3 Wire)
Simple PLC or control system interface.
RED – Positive supply
BLACK – Negative supply
GREEN – Control wire
Applying power to the GREEN wire moves the valve to its powered position.
Removing power from the GREEN wire returns the valve to its start position.
Failsafe Return (2 Wire)
Power ON moves the valve to its operating position.
Power OFF automatically returns the valve using the internal reserve power system.
A minimum of 1 minute power ON is required to fully recharge the reserve capacitors between failsafe operations.
Operating Speeds
9–24V AC/DC
Open: 7.5 seconds
Close: 8.5 seconds
110–240V AC
Open: 8 seconds
