Belimo 3-Way Characterized Valve Rp1-1/4 Kvs16 24-125VDC/24-240VAC Fail-Safe 75s 2-point 10Nm IP54 R3032-16-S3/NRFA

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 32 and the port size is Rp 1 1/4 inch with female threads. With its integrated characterizing disc, it ensures equal percentage flow control, enabling precise and consistent regulation of fluid flow. The maximum pressure differential is 3.5 bar (50.8 psi). The valve can operate between -10 and 120 °C (14 to 248 °F). The Kv value of the valve is 16 m3/h, equivalent to a Cv-value of 18.51 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 has an IP54 rating. The actuator is equipped with a fail-safe (NC) 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
