Description
Compact and precise water-side control
The Belimo R409K control ball valve is specially designed for controlling, switching or shutting off water flows in heating and cooling systems. The rotary ball valve design combines compact installation with reliable valve movement. The DN 10 sizing clearly indicates for which pipe diameter this execution is intended.
Together with a suitable actuator, the control ball valve forms a compact control unit. Depending on the execution, the water flow is controlled, shut off or switched between circuits.
Important features & benefits
- 2-way execution – Targeted control or shut-off of one water circuit
- DN 10 – Clear sizing for connection to the relevant pipe diameter
- External thread – Practical integration in the appropriate piping or installation concept
- G 3/4" – Practical integration in the appropriate piping or installation concept
- PN40 – Designed for reliable operation within the specified system pressure
- ps 1600 kPa – Designed for reliable operation within the specified system pressure
