Belimo Characterized Valve DN125 Flange Kvs250 24VAC/DC 90s MP-Bus 0-10/2-10V 40Nm IP54 R6125W250-S8/GR24A-MP-5

This is a Belimo 2-way characterized ball valve with a cast iron housing and EPDM sealing. The bore diameter of the valve is DN 125 and the flange size is DN 125. With its integrated characterizing disc, it ensures equal percentage flow control, enabling precise and consistent regulation of fluid flow. The maximum pressure differential is 4 bar (58 psi). The valve can operate between -10 and 120 °C (14 to 248 °F). The Kv value of the valve is 250 m3/h, equivalent to a Cv-value of 289.25 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 can be mounted on the valve via the ISO 5211 flange. 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 rotary or butterfly valve with a mounting flange. The mounting orientation relative to the valve can be selected 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:

• The integrated characterized disc ensures equal percentage flow, ideal for heating circuits
• This modulating actuator can position the valve anywhere between 0-90 degrees with a control signal of 0-10 V/2-10 V
