Proportional valve assembly for refrigerant

A proportional valve arrangement for refrigerant comprising:

• a valve housing comprising a valve body chamber,
• a valve body which is arranged within the valve body chamber and which is configured to be transferable between a first sealing seat and a second sealing seat,
• an electrically operable drive which is connected to the valve body via a spindle, wherein:
• a closing device is arranged between the spindle and the valve body;
• wherein
• the closing device is configured to generate an axial preload between the valve body and the first sealing seat when the valve body abuts against the first sealing seat;
• the closing device is configured to generate an axial preload between the valve body and the second sealing seat when the valve body abuts against the second sealing seat;
• the valve body comprises a stepped mounting space configured to receive the spindle and the closing device;
• the closing device comprises a spring element arranged coaxially with respect to the spindle;
• the spring element is configured to cause an axial preload between the spindle and a first stop of the stepped mounting space;
• and
• the spring element is configured to cause an axial preload between the spindle and a second stop of the stepped mounting space.
