New family of high-capacityelectronic expansion valves

By Chemical Engineering |

DunAn Microstaq

The VHC-MSEV family of modular silicon expansion valves (photo) provides cooling capacities ranging from 25 to 50 tons. The electronically controlled, normally closed and one-directional flow valves can be used for refrigerant mass-flow control in industry-standard HVAC and refrigeration systems. The VHC-MSEV provides precise superheat control and quick mass-flow adjustments through a closed-loop control methodology achieved with this company’s Universal SuperHeat Controller (USHC). — DunAn Microstaq, Inc., Austin, Tex.
