Electric Refrigerant Valves

 

Modulating Refrigerant Valve

The MVS industrial electronic control valve utilizes electronic controls to regulate both liquid and vapor refrigerant flows.

 

  Product Overview

     Specification

The MVS electronic control valve provides precise management of flow for a variety of industrial and commercial refrigeration applications. Due to this precise control systems it will run more efficiently and with less charge which reduces operating costs and increases system safety. As an additional benefit the MVS is a normally closed valve which means that it will move to a fully closed position in the event of a power loss. This feature reduces complexity by eliminating the need for an upstream solenoid valve or power backup module.

MVS valves can be applied to manage liquid levels in vessels, liquid injection for compressor cooling, superheat for direct expansion evaporators, brine temperature in chillers, hot gas for defrost, and countless other installations.
