The Modular Silicon Expansion Valve (MSEV) is an electronically controlled, normally closed and single flow directional valve. It can be used for refrigerant mass flow control for today’s industry-standard HVAC and Refrigeration applications. The MSEV provides precise superheat control and quick mass flow adjustments through a closed loop control methodology achieved with DMQ’s Universal SuperHeat Controller (USHC). Embedded with the silQflo® Silicon Servo Valve (SSV), the MSEV is the fastest responding refrigerant expansion valve in the industry.
