Description
½"–1" Stainless Steel 3-Way Modulating Ball Valve – ABVSV3TL/9M
The ABVSV3TL/9M Series stainless steel 3-way motorised ball valves provide proportional flow control, mixing and diverting for HVAC, chemical processing, water treatment and industrial automation applications.
Available in ½", ¾" and 1" BSP sizes, these valves combine corrosion-resistant SS304 stainless steel construction, PTFE/FKM (Viton®) seals and a compact IP67 electric modulating actuator.
Featuring 4–20mA control as standard, with optional 0–5V or 0–10V inputs, all three configurations provide 4–20mA analogue position feedback. L-Port and T-Port flow arrangements, NPN fault monitoring, manual override and supercapacitor failsafe options are available.
Valve Specifications
Valve Type: 3-Way proportional modulating stainless steel ball valve

Valve Orifices: 12mm, 15mm, 18mm respectively
Flow Configuration: L-Port or T-Port
Operating Pressure: 0–10 bar
Body, Ball & Internals: SS304 Stainless Steel
Valve Seats: PTFE
Seals: FKM (Viton®)
Media Temperature: 0°C to +90°C

Optional Connections: NPT Female
Media compatibility must be checked against SS304 stainless steel, PTFE and FKM seals, taking account of fluid concentration, temperature and operating conditions.
3-Way Flow Configurations
L-Port: Connects two of the three ports, allowing flow to be diverted between alternative flow paths.
T-Port: Provides additional mixing, diverting and flow distribution arrangements depending on ball orientation.
Available T-Port arrangements:
- Flow D – Standard
- Flow A, B or E – Optional
Important: L-Port and T-Port configurations have different flow paths. The required port connections, intermediate positions and failsafe position must be confirmed against the relevant flow diagram before ordering.

Modulating Control & Position Feedback
The ABV/9M actuator provides proportional valve positioning across its 90° operating range, with 4–20mA analogue feedback available for all three principal control inputs.
Control Input / Position Feedback:
- 4–20mA / 4–20mA – Standard
- 0–5V / 4–20mA – Optional
- 0–10V / 4–20mA – Optional
- 1–5V / 1–5V – Special order
Position feedback allows compatible PLC, BMS and industrial control systems to monitor actuator position independently of the selected control input.
Actual flow distribution depends on the internal L-Port or T-Port ball configuration, pressure differential and valve position. Actuator position is not necessarily proportional to flow rate.
Electrical Wiring & NPN Fault Output
Power Supply:
- RED – Positive 12–24V DC
- BLACK – Negative DC supply
Modulating Control:
- GREEN – Positive analogue control input
- BLUE – Signal common
Position Feedback:
- WHITE – Positive analogue feedback output
- BLUE – Signal common
NPN Fault Status – YELLOW Wire:
- Normal: NPN ON – Connected to BLACK (0V)
- Fault / blockage: NPN OFF – Open circuit
- Maximum Switching Voltage: 25V DC
- Maximum Switching Current: 100mA
The NPN output provides a separate fault indication for compatible PLC and BMS monitoring circuits. It is a switching output, not an analogue signal or positive-voltage supply.
Optional Failsafe Return – ABVSV3TL/9MAR
The optional ABV/9MAR supercapacitor-powered failsafe actuator automatically returns the valve to its specified safe position following loss of electrical power.
Available Failsafe Configurations:
- 4–20mA input / 4–20mA feedback – Standard stocked
- 0–10V input / 4–20mA feedback – Available
- 0–5V input / 4–20mA feedback – Available on request
Failsafe Features:
✓ Automatic return to a predetermined valve position
✓ 4–20mA analogue position feedback
✓ NPN fault output rated 25V DC / 100mA maximum
✓ Approximately 1.5–2 minutes capacitor recharge time with power applied
The required failsafe position and L-Port/T-Port flow arrangement must be specified when ordering. Repeated power interruptions before recharge is complete may prevent another full failsafe operation.
Failsafe operation is optional and is not included with the standard ABVSV3TL/9M.
