Hydraulic distribution manifolds

Model : MBV

Function

This device consists of several different functional components, each of which meets specific requirements, typical of the circuits used in heating and air-conditioning systems.

· Hydraulic separator

To keep connected hydraulic circuits totally independent from each other.

. Dirt remover

To permit the separation and collection of any impurities present in the circuits. Provided with a valved connection with discharge piping.

· Automatic air vent

For automatic venting of any air contained in the circuits.Provided with a valved connection for maintenance purposes.

· Insulation

The separators are supplied complete with pre-formed shell insulation to ensure perfect thermal insulation when used in both hot and cold water systems.

Operating principle
When a single system contains a primary production circuit, with its own pump, and a secondary user circuit, with one or more distribution pumps, operating conditions may arise in the system whereby the pumps interact, creating abnormal variations in circuit flow rates and pressures.

The hydraulic separator creates a zone with a low pressure loss, which enables the primary and secondary circuits connected to it to be hydraulically independent of each other; the flow in one circuit does not create a flow in the other if the pressure loss in the common section is negligible.

In this case, the flow rate in the respective circuits depends exclusively on the flow rate characteristics of the pumps, preventing reciprocal influence caused by connection in series. Therefore, using a device with these characteristics means that the flow in the secondary circuit only circulates when the relevant pump is on, permitting the system to meet the specific load requirements at  that time.

When the secondary pump is off, there is no circulation in the secondary circuit; the whole flow rate produced by the primary pump is by-passed through the separator.

With the hydraulic separator, it is thus possible to have a production circuit with a constant flow rate and a distribution circuit with a variable flow rate; these operating conditions are typical of modern heating and
air-conditioning systems.

Three possible hydraulical balance situations are shown below.
