Rotary valve HRB3 PN10 20/ kVs=6.3 PN10, female thread Rp 3/4 inch 065Z0405

Rotary valve for precise heat regulation

This HRB3 PN10 rotary valve, with a nominal diameter of DN20 and a flow coefficient of kVs 6.3, is a reliable solution for temperature regulation in heating systems. Made of dezincification-resistant brass (DZR), it ensures durability and corrosion resistance, which is crucial in water installations. Designed to work with Danfoss AMB 162 and AMB 182 actuators, it enables automatic flow control. A 3/4 inch Rp internal thread facilitates installation and integration with existing systems.

This valve is widely used in heating systems where very precise valve characteristics are not required, and a slight leakage in the closed position is acceptable – typical for most boiler systems. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.

Construction and user features

The HRB3 valve stands out with a well-thought-out design that translates into ease of use and installation. The ergonomic lever facilitates manual adjustment, and the position indicator is visible even after the actuator is mounted, allowing for a quick assessment of the valve status. Minimal leakage in the class ensures effective temperature regulation and reduces energy losses.

• Material: Dezincification-resistant brass (DZR) – guarantees durability and corrosion resistance.
• Connection: Rp 3/4 inch internal thread – standard size facilitating integration with existing installations.
• Kvs coefficient: 6.3 – optimal flow for medium-performance systems.
• Nominal pressure: PN10 – safe operation in standard heating installation conditions.
• Position indicator: Visible even after actuator mounting – facilitates valve status control.
• Ergonomic lever: Provides convenient manual flow adjustment.

Applications and compatibility

The HRB3 rotary valve is a universal solution for professionals and end-users. It will work in:

• Central heating systems powered by gas, oil or electric boilers.
• Heating installations in residential, commercial and industrial buildings.
• Domestic hot water temperature regulation systems (taking into account the permissible content of antifreeze agents up to 50%).

The valve meets safety and quality standards, which confirms its reliability and long-term operation. It is compatible with a wide range of Danfoss actuators, providing flexibility in choosing the appropriate automation system.
