Belimo 3-Way Ball Valve G1-1/4 Kvs21 24VAC/DC 100s 2/3-point 2Nm IP40 R520/TR24
This is a Belimo 3-way ball valve with a nickel-plated brass housing and EPDM sealing. The bore diameter of the valve is DN 20 and the port size is G 1 1/4 inch with male threads. The maximum pressure differential is 4 bar (58 psi). The valve can operate between -10 and 100 °C (14 to 212 °F). The Kv value of the valve is 21 m3/h, equivalent to a Cv-value of 24.3 gpm. The actuator requires a supply voltage of 24 V AC/DC. The actuator features two-point and three-point control. The actuator opens/closes the valve in 100 seconds. The actuator has an IP40 rating.

Description
This is a Belimo 3-way ball valve with a nickel-plated brass housing and EPDM sealing. The bore diameter of the valve is DN 20 and the port size is G 1 1/4 inch with male threads. The maximum pressure differential is 4 bar (58 psi). The valve can operate between -10 and 100 °C (14 to 212 °F). The Kv value of the valve is 21 m3/h, equivalent to a Cv-value of 24.3 gpm. The actuator requires a supply voltage of 24 V AC/DC. The actuator features two-point and three-point control. The actuator opens/closes the valve in 100 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:
- Manual override
- Visual position indicator
Cons:
- The time to open/close of 105 s is slow for some applications
