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.
Type direct-controlled ball seat valve | Mounted position any |
Sealing | Max. operating pressure 320 bar |
Medium HFA, clear water | Ambient temperature max. +35°C |
Connections plate mounting with O-Ring seal | Operating voltage 24 V DC |
Operating temperature +5°C bis +55°C |
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.
