Description
The Trane VAL19891 is a Thermal Expansion stopcock( TXV) used with R410a refrigerant in Trane HVAC systems, such as air conditioners and heat pumps. This stop cock has a paramount role in controlling the admission of refrigerant in the system. Some people tend to describe it as a pressure-controlled doorkeeper. By sensing the pressure and temperature of the refrigerant, the TXV regulates the flow of the refrigerant through the opening of a stopcock, the amount of refrigerant that is allowed into the evaporator coil. Such a controlled inflow makes it possible to have the right amount of heat that can be immersed in your home as well as the right cooling. The Trane is typically made with long-lasting accoutrements for long- continuing performance.
