Description
½"–2" UPVC 3-Way Modulating Motorised Ball Valve – ABV3P/9M
The ABV3P/9M Series 3-way motorised UPVC ball valves provide precise proportional flow control, mixing and diverting for industrial automation, water treatment, chemical dosing and process-control applications.
Available from ½" (DN15) to 2" (DN50), these electrically actuated valves combine a corrosion-resistant true union UPVC valve body with a compact IP67 proportional modulating actuator.
Supporting 4–20mA, 0–5V or 0–10V control inputs with 4–20mA valve position feedback, the ABV3P/9M is designed for Building Management Systems (BMS), PLC automation, HVAC, water treatment and industrial fluid-control systems.
Available with L-Port or T-Port flow configurations, integrated NPN actuator fault-status output, manual override and optional capacitor-powered failsafe return.
Standard BSP threaded connections are complemented by optional NPT, metric and imperial solvent-weld socket connections, subject to availability.

3-Way Ball Valve Flow Configurations
The ABV3P/9M is available with L-Port or T-Port ball configurations for automated flow routing, mixing, diverting and proportional flow distribution.
The internal ball configuration determines which valve ports communicate as the actuator rotates.
L-Port Configuration
An L-Port ball connects two of the three valve ports, allowing flow to be directed between alternative flow paths.
Typical applications include:
✓ Automated Flow Diverting
✓ Two-Path Flow Selection
✓ Industrial Process Switching
✓ Water Treatment Equipment
✓ HVAC Flow Routing
T-Port Configuration
A T-Port ball incorporates a three-way internal passage, providing additional flow routing arrangements depending on the selected ball orientation.
Available T-Port Flow Arrangements:
- Flow D – Standard
- Flow A
- Flow B
- Flow E
Depending on the selected configuration, T-Port valves can provide:
✓ Flow Mixing
✓ Flow Diverting
✓ Multi-Port Flow Distribution
✓ Automated Process Routing
✓ Proportional Flow Distribution
**Important:** L-Port and T-Port configurations have different internal flow paths. Not every configuration permits the same mixing, diverting or intermediate-position operation.
The required flow diagram, port arrangement and actuator travel should be confirmed before ordering.
Media Compatibility & Temperature
Suitable Media, Subject to Material Compatibility:
- Water
- Process Water
- Air
- Compatible Chemicals
- Salt Solutions
- Dilute Acids
- Dilute Alkalis
- Chemical Dosing Solutions
- Compatible Industrial Liquids
Media compatibility must be checked against the UPVC valve body, PTFE seats and selected EPDM or FKM sealing materials.
EPDM Seals
Suitable for water and many dilute chemical solutions where EPDM is chemically compatible with the process medium.
FKM (Viton®) Seals
An alternative sealing material for applications involving compatible oils, chemicals and industrial fluids where EPDM may be unsuitable.
Maximum Media Viscosity: 100 cSt
Media Temperature: +2°C to +90°C stated range, subject to confirmation of the valve manufacturer's UPVC material and pressure/temperature limits

Modulating Control & Position Feedback
The ABV3P/9M supports proportional valve positioning using industrial analogue control signals.
The actuator adjusts the 3-way ball position according to the selected control input, allowing intermediate positioning between its programmed operating limits.
This enables automated regulation of flow distribution where supported by the selected L-Port or T-Port configuration.
Available Control Inputs
✓ 4–20mA – Standard stocked configuration
✓ 0–5V – Optional
✓ 0–10V – Optional
✓ 1–5V – Special-order matched input/output configuration
Valve Position Feedback
✓ 4–20mA proportional feedback with 4–20mA control input
✓ 4–20mA proportional feedback with 0–5V control input
✓ 4–20mA proportional feedback with 0–10V control input
✓ Optional matching 1–5V input and 1–5V feedback version
The 4–20mA feedback signal allows compatible PLC, BMS and process-control systems to monitor actual actuator position independently of the selected control input.
A matching 0–5V input/output configuration is not available.
Electrical Wiring & Signal Connections
Power Supply
RED Wire – Positive 12–24V DC supply
BLACK Wire – Negative DC supply / common
Modulating Control Input
GREEN Wire – Positive analogue control input
BLUE Wire – Signal common / negative
Input signal depends on the selected actuator configuration.
Proportional Position Feedback
WHITE Wire – Positive analogue position feedback output
BLUE Wire – Signal common / negative
Standard Feedback Output: 4–20mA
Special-order matching 1–5V input/output configuration available.
Actuator Fault-Status Output
YELLOW Wire – NPN switching fault-status output
Normal Operation: Yellow output electrically connected to black common.
Valve Blocked: Yellow output disconnected from black common.
This output provides a switching indication for compatible PLC, BMS and external monitoring circuits.
The yellow wire is not a proportional position feedback signal.
Electrical output ratings and external circuit requirements should be confirmed before connection.
Modulating Performance
Operating Time: Approximately 12 seconds for 90° travel
Positioning Range: 0–90°
Position Resolution: 75 individual positioning steps
Step Resolution: 1.2° nominal
Continuous Duty: 100%
The actuator provides intermediate valve positioning in response to the applied analogue control signal.
For 3-way valves, actual flow distribution depends on the internal ball drilling, selected flow configuration, pressure differential and valve position.
Intermediate positioning does not necessarily produce a linear relationship between control signal and flow rate.
Optional Capacitor-Powered Failsafe Return
The ABV3P/9M Series is available with an optional ABV/9MAR failsafe modulating actuator.
The failsafe version incorporates an electrical energy-storage system designed to return the valve to a predetermined safe position following loss of power.
✓ Automatic failsafe positioning following power failure
✓ Capacitor-powered return system
✓ 4–20mA control with 4–20mA position feedback – standard stocked failsafe configuration
✓ Optional 0–5V or 0–10V control with 4–20mA feedback – available to special order
✓ Suitable for industrial process protection and automated control systems
Failsafe Capacitor Recharge Requirement
A minimum of approximately 1.5–2 minutes with electrical power ON is required to recharge the reserve capacitors between failsafe operations.
Repeated power interruptions before the capacitors have fully recharged may prevent the actuator from completing another failsafe return.
The required failsafe position and 3-way flow configuration must be specified when ordering.
True Union UPVC Valve Construction
The true union design allows the centre valve assembly to be removed from the pipeline without disturbing the adjoining pipework.
This simplifies inspection, cleaning, seal replacement and maintenance, particularly in water treatment and chemical dosing equipment.
Benefits include:
✓ Removable Centre Valve Assembly
✓ Simplified Maintenance
✓ Easy Seal Inspection
✓ Reduced Pipeline Disruption
✓ Corrosion-Resistant UPVC Construction
✓ Choice of EPDM or FKM Seals

Modulating vs Open/Close Control
The ABV3P/9M Modulating Series is designed for applications requiring intermediate valve positioning rather than simple fully open or fully closed operation.
Choose the modulating version where the control system needs to:
✓ Command Intermediate Valve Positions
✓ Adjust Flow Distribution
✓ Control Mixing or Diverting Arrangements
✓ Receive Analogue Position Feedback
✓ Integrate with PLC, BMS or SCADA Systems
✓ Monitor Actuator Fault Status
For applications requiring only fixed-position switching, the standard ABV3P open/close series may be more appropriate.
For applications requiring automatic positioning following loss of electrical power, select the optional ABV/9MAR failsafe configuration.
Proven Actuator Reliability
The ABV Series electric modulating actuator has a manufacturer-rated service life of approximately 70,000 operating cycles.
During Connexion Developments' in-house endurance testing, the actuator successfully completed over 977,000 open and close cycles.
This extended endurance test demonstrates the actuator's potential for long-term operation in demanding automated valve applications.
Actual service life depends on operating conditions, valve loading, switching frequency and maintenance.
