Orifice tube expansion valve

Here is a short clip of under the hood. His spec sheet is calling for an expansion valve instead of an orifice tube , but I dont see one where he. It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the.

The expansion tube , better know as a fixed orifice tube (FOT), is a nonadjustable device that has a fixed orifice metering element and a fine-mesh strainer. Unlike the expansion valve , has not remote bulb and does not vary the amount of refrigerant entering the evaporator in the same manner.

The thermostatic expansion valve (TXV) is a precision device, which is designed to regulate the rate at which liquid refrigerant flows into the evaporator. Expansion Devices Full Product Listing. This controlled flow is necessary to maximize the efficiency of the evaporator while preventing excess liquid refrigerant from returning to the compressor (floodback). On ac gauges, with proper refrigerant charge, I show slightly low high side pressure, but very very low low side pressure.

A wide variety of orifice expansion valve options are available to you, There are orifice expansion valve suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Taiwan, and Hong Kong, which supply , , and of orifice expansion valve respectively. An expansion valve system also has the compressor running all the time when cooling with the valve preventing the evaporator from freezing and maintaining proper pressures. The orifice tube will change the high pressure liquid refrigerant into a low pressure liquid refrigerant. Once you seperate this line at the stationary fitting and flare nut, you can pull the orifice tube out with a pair of needle nose pliers.

The VOV is an improvement in performance over the fixed orifice valve , because like a TXV, it can change its output based on operating conditions. Smart Valve Orifice Tube - Retrofit Orifice Tube Brown Orifice Tube with Green HNBR O-Rings (R-134a). The valve senses the refrigerant level an when neede injects liquid to keep the air conditioning system.
