Belimo 6-Way Characterized Valve Rp3/4 Kvs0.63/4 24VAC/DC 90s BACnet/Modbus/MP-Bus 5Nm IP54 R3020-P63-4-B2/LR24A-MOD

This is a Belimo 6-way characterized 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 Rp 3/4 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 1 bar (14.5 psi). The valve can operate between 6 and 80 °C (43 to 176 °F). The Kv value 1 of the valve is 0.63 m3/h, equivalent to a Cv-value of 0.73 gpm. The Kv value 2 of the valve is 4 m3/h, equivalent to a Cv-value of 4.63 gpm. The actuator requires a supply voltage of 24 V AC/DC. The actuator supports BACnet MSTP/Modbus RTU/MP-Bus communication protocols and requires product ZTH EU for setting the protocol address and linking the actuator to the system. Furthermore, ZTH EU allows the setting of an analog 0-10V or 2-10V control signal. The actuator opens/closes the valve in 90 seconds. The actuator has an IP54 rating.

Pros:

• The integrated characterized disc ensures equal percentage flow, ideal for heating circuits
• Modulating actuator with fieldbus or a 0-10 V/2-10 V signal
• Manual override
• The actuator is overload protected
• Visual position indicator

Cons:

• Product ZTH EU needed (not included) to set protocol address and link the actuator to the system
• The time to open/close of 90 s is slow for some applications
