Hello, good afternoon, people from the forum, thank you for your collaboration with the newbies on the subject. Well, I will explain to you, I need to know how to replace a VET valve that has the bulb cut off and is so old that it has no data, since I am putting together a 5-door counter refrigerator with two evaporators with a forger and it has a compressor motorcycle 1/2 hp with r134, it is for cooling drinks. In the area where I live the nearest refrigeration houses are 1000 or 2000 km away Atte. Emilio
