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.
