Belimo Characterized Valve DN80 Flange Kvs100 24VAC/DC Fail-Safe NC/NO 150s 2-10V 40Nm IP54 R6080W100-S8/GRK24A-SR-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 80 and the flange size is DN 80. 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 100 m3/h, equivalent to a Cv-value of 115.7 gpm. The actuator requires a supply voltage of 24 V AC/DC. The modulating actuator is requires a 2-10 V input and offers position feedback, ensuring precise control over its operation and accurate monitoring of its position within the designated voltage range. The actuator opens/closes the valve in 150 seconds. The actuator can be mounted on the valve via the ISO 5211 flange. The actuator has an IP54 rating. The actuator is equipped with a fail-safe (NC/NO) feature that ensures safe operation in the event of a power failure.

The actuator opens/closes the valve in 150 seconds. The actuator can be mounted on the valve via the ISO 5211 flange. The actuator has an IP54 rating. The actuator is equipped with a fail-safe (NC/NO) feature that ensures safe operation in the event of a power failure.
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 moves the valve to the desired operating position simultaneously as the integrated capacitors charge. If the power supply is interrupted, the valve shifts to the chosen fail-safe position using the stored electrical energy. The rotation angle can be adjusted with mechanical end stops. The capacitor actuators require a pre-charging period to bring the capacitors to a usable voltage level. This ensures that, in case of a power failure, the actuator can move from its current position into the fail-safe position at any time. The rotary knob fail-safe position allows for adjusting the preferred fail-safe position. In case of a power outage, the actuator moves to the selected fail-safe position, considering the factory-set bridging time of 2 seconds. Post-factory delivery, the actuator is fully discharged and requires about 20 seconds of pre-charging before initial setup to attain the necessary voltage level in the capacitors.
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 2-10 V
- The actuator is equipped with a fail-safe feature
