This is a Belimo 3-way ball valve with a nickel-plated brass housing and EPDM sealing. The bore diameter of the valve is DN 40 and the port size is Rp 1 1/2 inch with female threads. The maximum pressure differential is 10 bar (145 psi). The valve can operate between -10 and 120 °C (14 to 248 °F). The Kv value of the valve is 31 m3/h, equivalent to a Cv-value of 35.87 gpm. The actuator requires a supply voltage of 24 V AC/DC. The actuator features BACnet IP/Modbus TCP control, enabling versatile communication and interoperability with other systems for streamlined control and monitoring capabilities. The actuator opens/closes the valve in 90 seconds. The actuator has an IP40 rating.
The actuator, equipped with overload protection, doesn’t need limit switches and will stop automatically when the end stop is reached. Manual override is possible using a push-button, which disengages the gear train as long as the button is pressed or remains locked. Manual triggering of adaptation can be done by pressing the “Adaptation” button. Both mechanical end stops are detected during the adaptation (entire setting range). The actuator then moves into the position defined by the control signal. The actuator can be directly mounted on the ball valve using a single screw. The mounting orientation relative to the ball valve can be chosen in 90° increments. The actuator is controlled via the Cloud, BACnet IP, or Modbus TCP and moves to the position defined by the control signal. Various data points can be written and read via the same interfaces. In hybrid mode, the actuator receives its analog control signal from the higher-level controller and moves to the defined position. Various data points can be read and written (except for the control signal) using the Cloud, BACnet IP, or Modbus TCP. The rotation angle can be adjusted with mechanical end stops. The recorded data (integrated data recording for 13 months) can be utilized for analytical purposes. CSV files can be downloaded via a web browser. Upon initial power supply, i.e., during commissioning, the actuator performs an adaptation where the operating range and position feedback adjust to the mechanical setting range. The actuator then moves into the position defined by the control signal.
Pros:
- Manual override
- The actuator is overload protected
- Visual position indicator
Cons:
- The time to open/close of 90 s is slow for some applications
