Hydraulic Header – 2m3/hr (50 Kw Set @ 20oC Δ T )

The Insulated Modvlvs Hydraulic Header is connected before the Distribution Header and hydraulically isolates the primary and secondary circuits; this allows the primary flow to be maintained at boiler manufacturer’s requirements and provides greater volumetric flow in the Distribution Header to all circuits. Specification of Hydraulic Header: –


Centre distance: 1” Male BSP = 125mm.

1” Female BSP = 250mm

Insulation Box Measurements: 110x110x142 mm.


PN 10 Max Temperature: 110°C


Connections: 1” Male BSP to the Modvlvs Distribution Header.

                           1” Female BSP to the Boiler

½” Female BSP Sensor Connection to the Boiler


Hydraulic Header Code: HW60/125-04


Applications: Up to 50 kW (with Δt 20 c) and maximum flow 1500 l/h.
