- with adjustment scale
- Differential pressure fully adjustable
- either space-saving angled version or straight version
For keeping the pump pressure in sealed heating systems as per EN 12828 constant and for reducing flow noise in the heating system.
Differential pressure bypass valve with directly readable adjustment scale. Housing made of brass. Available as straight version or angled version for space-saving installation. The differential pressure in the heating system at full load is set directly at the bypass valve. If the volume flow is reduced, the valve opens to keep the head of the circulation pump constant.
