Belimo 3-Way Characterized Valve G1 Kvs1.6 100-240VAC 35s 2/3-point 2Nm IP40 R511/TRY230

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 port size is G 1 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 2 bar (29 psi). The valve can operate between 6 and 100 °C (43 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 100-240 V AC. The actuator features two-point and three-point control. The actuator opens/closes the valve in 35 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 has overload protection and automatically stops upon reaching the end stop. In case of blockage, the actuator switches off for seven seconds before attempting to restart. If the blockage persists, the actuator attempts to restart 15 times every two minutes and subsequently only once every two hours. 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 35 s is slow for some applications
