Sounds like you got things dialed in, but FWIW, I referenced the parts sheet and I believe what you are refering to is one of two parts (that are related). There's both an expansion valve as well as an expansion meter. The valve is a large cyclinder in line with copper tubing. The meter is a brass tee. Basically it's what Dan described above.
