Differential Pressure Control Valves (DPCV)

What is a DPCV?

Differential Pressure Control Valves - also commonly called DPCVs - are installed in heating or cooling systems to control sub-circuit pressure to a set or given maximum.

FlowCon’s DPCV range include three different types. A type with pre-set ΔpC (differential pressure across the circuit), a type with adjustable ΔpC and finally a type being a combined dynamic balancing valve and adjustable DPCV. They offer a flexible range meeting any system demand.

Why choose a DPCV?

With a DPCV installed in Your system, You will achieve reduced energy consumption, avoid the risk of annoying noise and have a simple commissioning process.

 

How does a DPCV works?

A DPCV includes a diaphragm, a spring and a capillary tube connecting the partner valve in the supply pipe and the DPCV valve in the return pipe to control the circuit pressure loss.

• ΔP Control

The DPCV diaphragm will regulate to control ΔpC (differential pressure across the circuit) depending on pressure impulse from the supply side and direct pressure from the return side. The spring force will equal the ΔpC.

In all FlowCon DPCVs the diaphragm will be a rolling diaphragm which will result in a very compact valve design. Depending on the FlowCon Differential Pressure Control Valve selected, ΔpC may be fixed or externally adjustable.
