Application
The 29M11 TXV is ideal for use in split-system air conditioners and heat pumps where accurate refrigerant flow control is critical. By responding dynamically to evaporator load changes, it ensures the correct amount of refrigerant enters the evaporator coil at all times — preventing flooding or starving conditions that can reduce efficiency or damage equipment.
