Belimo 3-Way Characterized Valve DN15 Flange Kvs1.6 24-125VDC/24-240VAC Fail-Safe NO 75s 2-point 10Nm IP54 SPDT R7015R1P6-B1/NRFA-S2-O

This is a Belimo 3-way characterized ball valve with a nickel-plated brass housing and EPDM sealing. The bore diameter of the valve is DN 15 and the flange size is DN 15. With its integrated characterizing disc, it ensures equal percentage flow control, enabling precise and consistent regulation of fluid flow. The maximum pressure differential is 1 bar (14.5 psi). The valve can operate between -10 and 100 °C (14 to 212 °F). The Kv value of the valve is 1.6 m3/h, equivalent to a Cv-value of 1.85 gpm. The actuator requires a supply voltage of 24-125 V DC / 24-240 V AC. The actuator opens/closes the valve in 75 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 (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. The valve can be manually operated and secured in any position using a hand crank. Unlocking can be done manually or automatically by applying the operating voltage. 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 equipped with a universal power supply module that can utilize supply voltages of AC 24-240 V and DC 24-125V. The actuator moves the valve to the operating position while also tensioning the return spring. The valve returns to the fail-safe position by spring force when the supply voltage is interrupted. The rotation angle can be adjusted with mechanical end stops.

Pros:

• The integrated characterized disc ensures equal percentage flow, ideal for heating circuits
• The actuator is equipped with a fail-safe feature
