Belimo Characterized Valve G3/4 Kvs0.63 230VAC 105s 3-point 2Nm IP40 R406DK/TR230-3

This is a Belimo 2-way characterized 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. 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 2 and 130 °C (36 to 266 °F). The Kv value of the valve is 0.63 m3/h, equivalent to a Cv-value of 0.73 gpm. The actuator requires a supply voltage of 230 V AC. The actuator features three-point (open-close) control. The actuator opens/closes the valve in 105 seconds. The actuator has an IP40 rating.

Manual override is possible using a lever, which disengages the gearing as long as the self-resetting lever is pressed. The actuator automatically switches off when end stops are reached, with a pulse duration of ≥0.5 s. 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.

Pros:

• The integrated characterized disc ensures equal percentage flow, ideal for heating circuits
• Manual override
• Visual position indicator

Cons:

• The time to open/close of 105 s is slow for some applications
