Description
The Emerson Flow Control (Alco) 057317 Externally Equalized Valve is used for the accurate control of refrigerant flow in HVAC systems. This valve has a 15-ton capability and 5/8”x7/8” ODF connections to guarantee its efficiency. Valves such as external are equalized so as to always counter the pressure drop felt across the evaporator coil, which optimizing superheat and efficiency. This leads to the ability to increase cooling capacity and decrease energy usage, as well as increase reliability of the overall system. It is an important part of larger air conditioning and refrigeration systems.
