    Because they can.

    I've seen those valves to many times. I like the screen inside a soldered inlet. Great just what I need.

    I think it all canes down to $.

    to remove the suction line is a miserable job..theres maybe 8" of room between the evaporator and the inside wall...I wish I could talk to the designer of the box and txv...

    The "fix" for that is diagnosing a "bad" TEV and installing a standard body valve.

    Eff that. It's not adjustable and you need a new one.

    It is not the design engineers you should blame. It is the commodity managers. They are the ones that insist on TXV pricing going down every year, and value upfront cost before all else.

    Actually, many OEMs want their TEVs factory set according to their specification, but also don't want technicians to have the ability to change that factory adjustment.

    This valve satisfies both requirements.

    So, it's not about the budget and it's not about some stupid engineer. It's really about the numerous techs who don't understand TEVs, and the OEMS feels more secure knowing the valve setting likely won't be altered from the factory setting.

    Almost all automotive TXVs are like that too. They're not meant to be adjusted.

    This is so true outside of Walk Ins and Supermarkets.
