Data sheet
AB-PM DN 40-100
AB-PM DN 40-100 is a combined differential pressure controller for dynamic hydronic balance.
• The valve should be able to ensure hydronic balance for each zone with one or more terminal units.
• Valve shall have flexible functionality as either DPCV or PIBCV.
• The valve can be connected to either flow or return pipe via impulse tube
• With impulse tube connected to flow, the valve should keep differential pressure across the
branch by membrane driven controller.
• With impulse tube connected to the return, the valve should control the flow on every terminal unit
• Valve should have shut-off function.
• Valve should have possibility to mount actuator without effecting presetting.
• Valve should have variable setting. Setting value should allow to set a combination of needed
differential pressure and flow for zone.
• Setting should be lockable to prevent unauthorized change.
• Control valve should have metal to metal sealing to ensure sufficient performance of differential
pressure control at low flows.
• Shut-off service function should be possible to do with hand or a tool. The Dp controller should
have soft sealing to ensure suficient closing in case of zero flow
• Valve should be delivered with min. 2.5 m impulse tube. Diameter of impulse tube should not be
bigger than 1.2 mm.
• Valve should be delivered in reliable packaging for safe transport and handling.
