Product Description

Frequently Asked Questions

Where can I source the CBM ROB40212 ball valve in your region?

3G Electric stocks the CBM ROB40212 2" ball valve available to order. We handle delivery to your location with full customs import and customs clearance. Lead time on request—contact our team for pricing and availability.

What is the flow capacity and pressure drop for this valve?

The CBM ROB40212 delivers Kv 390 for 2 inch ISO 228/1 connections. Pressure drop (ΔP in mm H2O) = 10,000 × flow [m³/h] ÷ 390. Minimum tightness angle is 7°. Ideal for industrial water systems with consistent flow control.

What materials are used in the CBM ROB40212 construction?

Body and ball are brass P-OT 58 Pb 2 with nickel-chromium plating on the ball. Stem packing uses NBR rubber O-rings; seats are virgin PTFE. This combination ensures durability and reliable sealing in water applications.

Used in

Common applications for CBM

Industrial boilers — CBM circulation pumps (mod. CM 30W) and solenoid valves (ELV series) for heating-loop control and pump staging.

Burner systems — CBM oil nozzles (FLU atomizer types), electrodes (ELC 200 mm), and solenoid coils (ELV 230V AC) for combustion ignition and flame supervision.

Plant maintenance and retrofit — CBM cable glands (CLI M25), motor couplings (ACC type D), and small-radius fittings (RAC 90°) for equipment reconfiguration and sensor integration.

Boiler water treatment — CBM chlorine test kits (DET free+combined) for feedwater and circulating-water quality monitoring in closed-loop systems.

Pump and motor assembly — CBM couplings, fittings, and cable glands for assembly and rewinding of industrial motors, circulation pumps, and auxiliary equipment.
