Reference: V3EFR
Brand: Belimo
Mfr. Part: R520/TRF230

This is a 3-way Belimo 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. This valve withstands pressure up to 40 bar (580 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 100-240 V AC. The actuator opens/closes the valve in 75 seconds. The actuator has an IP42 rating. The actuator is equipped with a fail-safe (NO) feature that ensures safe operation in the event of a power failure.

This is a 3-way Belimo 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. This valve withstands pressure up to 40 bar (580 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 is equipped with a fail-safe (NO) feature that ensures safe operation in the event of a power failure.

Manual override is possible using a lever, which disengages the gearing as long as the self-resetting lever is pressed. The actuator, equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. 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 simultaneously moves the valve to the operating position and tensions the return spring. If the power source is cut off, the valve reverts to the fail-safe position driven by the spring force.

Pros:

  • The actuator is equipped with a fail-safe feature
