The Modular Silicon Expansion Valve (MSEV) from DunAn Microstaq (DMQ) is a fast-responding electronic expansion valve that can be used in a variety of refrigeration applications, including display cases, freezers, and walk-in and reach-in coolers.
Series HSV electric expansion valves offers precise superheat control. The valves feature a direct drive linear actuator using a hybrid step motor that provides increased power for its size, and eliminates unnecessary parts and their associated failure potential, the company said.
One of the basic components selected when installing a walk-in cooler/freezer or any field-assembled refrigeration system is the metering device, typically the thermostatic expansion valve (TXV). The TXV needs to be selected to match the Btu capacity of the system’s evaporator and compressor.
Seven models of the universal TR6 thermostatic expansion valve cover OEM air conditioner and heat pump designs in a wide range of applications, from 1.5 to 6 tons in R-22 and R-410A systems. According to the manufacturer, they easily install into almost any residential air conditioning system.
While refrigeration in supermarkets information ran throughout sessions at the Food Marketing Institute Energy & Store Development Conference, it also found itself as a stand-alone topic during several concurrent breakout sessions and as a front and center focus of a general session.
