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

NW 10 FOR HFA AND WATER

  • Hermatically sealed off in blocked position
  • No internal leakages
  • Wear parts are easy to access and fast to replace
  • Regilation electronic is inserted in the magnet, no further control card is necessary
  • Direct-controlled seat valve operated by proportional magnet
  • Actuation magnet protected against dirt and humidity



Direct controlled 2 way proportional seat valve for the constant control of group HFA and clear water pressure media.

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 differences on the valve. In their standar version the valves are closed, when de-energized.

By using a desired value between 0-10 Volt or 0-20mA a varince control is made from a proportional magnet between the way sensor and the desired value. The result is handeled by the inserted electronic control.

The desired value will be reached by approximation of the lever to the actual value sensor. By this kind of way monitoring it is possible to assign any opening position to the valve and in case of that it is possible to controle the volume flow.

The sensor allignment is made automatically by the inserted electronics.

The parameterization of the valves is realized by using an infrared interface which is controlled by an external Windows© based software.

Area of application: As a main valve, pressure and flow rate regulation, as pilot valve, pressure, speed and depth control in connection with the appropriate main valve.
