INTRODUCTION
U.S. Solid 1/2-inch brass 3-way T-port motorized ball valve for switching or diverting flow in compatible non-potable fluid circuits. The 3-wire dual-control version uses separate OPEN and CLOSE inputs; at each end position, the actuator automatically cuts power and holds the valve position. The brass body uses a PTFE sealing ring and is rated for a maximum operating pressure of 16 bar. Confirm the thread, pressure, temperature, and electrical rating for your exact valve before installation.
HOW IT WORKS
FEATURES
APPLICATIONS
Use in compatible non-potable water circulation, hydronic heating and cooling loops, and systems using water mixed with up to 50% ethylene glycol. Select the T-port orientation and control method to match the system flow path.
Not for drinking-water service. Brass valves may contain lead; see the WARNING section.

FAQ
The ball's T-shaped passage routes flow between three ports. Confirm the port orientation and flow direction against your piping layout and the manual diagrams.
The 3-wire version uses separate OPEN and CLOSE control connections. It stays at the reached position and does not provide auto-return.
The supplied product data lists water and a solution containing up to 50% ethylene glycol. Confirm chemical compatibility with all system materials and stay within the rated pressure and temperature limits.
WARNING
- Brass valves may contain lead. Do not use this valve for drinking-water service.
- Disconnect the power supply before wiring or servicing. Use the voltage listed in the specifications and verify the wiring before connecting the supply.
- The manual instructs that the valve remain powered for at least 1 minute. Follow the wiring diagram and instructions before operation.
- Do not exceed 16 bar, 0–90 °C media temperature, or 0–60 °C ambient temperature. IP54 protects against dust ingress and splashing water; it is not an immersion rating.
