2/2 DIR. CONTR. PROPORTIONAL VALVE IN SEAT CONSTRUCTION

NW3 AND NW6 FOR HFA AND WATER

  • Hermatically sealed off in blocked position
  • No internal leakages
  • Actuation magnet protected against dirt
  • humidity
  • Wear parts are easy to access and fast to replace
  • Direct-controlled seat valve operated by proportional magnet
  • The proportional valve can be driven by a position control card BLS1


Application
direct-controlled 2 way proportional seat valve for the constant control of group HFA and clear water pressure media

Function
A constant electric input signal is converted into a proportional valve opening stroke by means of a proportional magnet. The volume flow is determined by the opening cross-section and the pressure difference on the valve. In their standard version the valves are closed when re-energized.
