GENERAL DESCRIPTION The FlowCon DPCV series are differential pressure control valves. Each valve has an adjustable differential pressure setting to enable differential pressure limitation for balancing or avoiding noise from the sub system that the valve is controlling. Furthermore, the DPCV can be used as a shut-off valve. The FlowCon DPCV is easy to adjust without special equipment or conversion tables since the setting is printed directly on the valve which is adjusted by hand. The valve is tamper-proof when the supplied lock ring is fastened with a cable binder.

Turn the top wheel by hand until the setting is reached. The picture shows a setting of 5 kPa (factory setting). For a more precise setting or to reach a setting in between the settings in the table, please measure the controlled differential pressure while adjusting the setting.
