This is a 2-way Belimo ball valve with a brass housing and EPDM sealing. The bore diameter of the valve is DN 10 and the port size is G 3/4 inch with male threads. The maximum pressure differential is 8 bar (116 psi). The valve can operate between 2 and 130 °C (36 to 266 °F). The Kv value of the valve is 4 m3/h, equivalent to a Cv-value of 4.63 gpm. The actuator requires a supply voltage of 24 V AC/DC. The actuator utilizes the MP-Bus communication protocol and provides position feedback in the range of 0-10 V or 2-10 V, allowing for precise control and accurate monitoring of its position within the specified voltage range. The actuator opens/closes the valve in 90 seconds. The actuator has an IP54 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. 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 connects with a 0-10 V control signal and moves to the position defined by the signal. Voltage measurement is employed both for visually displaying the valve position within the 0.5% to 100% range and as a control signal for other actuators. In bus operation, the actuator receives its digital control signal from the upper-level controller via the MP-Bus and moves to the defined position. The U connection serves as a communication interface without providing an analog measuring voltage. The rotation angle can be adjusted with mechanical end stops.
Pros:
- This modulating actuator can position the valve anywhere between 0-90 degrees with a control signal of 0-10 V/2-10 V
