Huh? The pdf does not describe that. I am referring to the right angle Tvx. It says remove the Tvx.

A thermostatic expansion valve (TXV) is built up around a thermostatic element separated from the valve body by a diaphragm. Its purpose is to regulate the rate at which refrigerant flows into the evaporator.

TXVs can contain one of three different types of charge:

universal charge
Maximum operating pressure (MOP) charge.
MOP charge with ballast (standard for Danfoss expansion valves with MOP).
