English term or phrase: Front seat the suction valve
Looking for the proper translation for front seating (and back seating) a valve.
I do have an explanation from my client, but cannot find any good translation for it

Explanation:
If the valve stem is all the way out, the valve is considered to be in the back-seated position. The gauge port is closed and the valve is open, allowing refrigerant to flow through the system. If the valve stem is all the way in, the valve is considered to be in the front-seated position. The gauge port is open to the compressor connection and the refrigerant line (suction or discharge) connection is closed.

front seat the suction valve
fermer le clapet d'aspiration


Explanation:
"If the valve stem is all the way out, the valve is considered to be in the back-seated position"
bach-seated : la tige est à distance du siège, la clapet est ouvert

voir schéma ici :
"Service valves can be set to three different positions (Figure 3):

Front seated position The valve stem is turned fully clockwise to effectively stop the flow of refrigerant vapour from the suction line union on the low pressure side of the compressor and to the discharge line union on the high pressure side of the compressor.

Back seated position The valve stem is turned fully counter-clockwise to stop the flow of refrigerant vapour to the gauge port of the service valve. "

"Be sure that the suction and the discharge service valves on the optional pumpout compressor are open (back-seated) during operation. Rotate the valve stem fully counterclock-wise to open. Frontseating the valve closes the refrigerant line and opens the gauge port to
compressor pressure."
