WRAS 3 Way Motorised Stainless Steel Ball Valve Mini Series – ABVMS3TL
The ABVMS3TL® is a compact WRAS approved 3-way motorised stainless steel ball valve designed for automatic diverting, mixing and changeover applications in potable water and compatible fluid systems.
Available with L-Port or T-Port ball configurations, the valve provides flexible flow control with up to four T-Port flow patterns, making it ideal for building management systems (BMS), solar thermal installations, rainwater harvesting, grey water systems, heating controls and water treatment applications.
Manufactured from 304 stainless steel with WRAS approved EPDM/PTFE seals, the ABVMS3TL® combines excellent corrosion resistance with reliable bubble-tight shut-off and low power motorised operation. The IP67 actuator is continuously rated for 100% duty operation and is available with Power Open/Close or Failsafe Return control options.

Control Options
Failsafe Return (2 Wire)
Power ON drives the valve to its operating position before automatically removing power from the motor.
Power OFF returns the valve to its start position using the internal reserve power system.
Approximately 1 minute of applied power is required to fully recharge the reserve capacitors.
Power Open / Power Close (3 Wire)
Ideal for PLC and Building Management System (BMS) control.
The valve remains in its commanded position when power is removed.
Available Voltages
9–24V AC/DC
110–240V AC 50/60Hz
L-Port & T-Port Configurations
The ABVMS3TL® is available with either an L-Port or T-Port stainless steel ball.
L-Port
Designed for flow diversion, allowing one inlet to be switched between two outlet ports.
T-Port
Provides four selectable flow configurations:
TA
TB
TD
TE
These configurations allow diverting, mixing and changeover functions depending on the installation requirements.
Optional Features
Manual Override
Allows manual valve operation without electrical power.
(Available on 9–24V models.)
E2 Position Feedback Switches
Volt-free fully OPEN and fully CLOSED end-of-travel confirmation switches.
ABVM Weather Cover
Provides additional protection for outdoor installations.

Building Management Systems (BMS)
HVAC control
Solar thermal systems
Domestic hot water systems
Rainwater harvesting
Grey water recycling
District heating
Heat interface units (HIUs)
Tenant heat metering
Caravans
Motorhomes
Canal boats
Water treatment
Automatic changeover systems
Mixing and diverting duties
Why Choose the ABVMS3TL?
Unlike conventional 2-way valves, the ABVMS3TL® provides automatic flow diversion and changeover using either L-Port or T-Port ball configurations. Combined with WRAS approved materials, IP67 protection and configurable failsafe or Power Open/Close control, it provides a compact, reliable solution for potable water and building services applications.
Its combination of stainless steel construction, WRAS approval and multiple flow path options makes it particularly suitable for professional installers requiring dependable automatic valve control in clean water systems.
