Very High Capacity Modular Silicon Expansion Valve (VHC-MSEV)
An electronically controlled expansion valve that is powered by silQflo® Silicon Servo Valve MEMS technology. The VHC-MSEV is the fastest responding refrigerant expansion valve in the HVAC and refrigeration industry. It is a normally closed and one directional flow valve that can be used for refrigerant mass flow control for today’s systems.
Like the MSEV (for sub 8 tons cooling capacities) and HC-MSEV (10 – 25 tons), the VHC-MSEV provides precise superheat control and quick mass flow adjustments through a closed loop methodology with the Universal SuperHeat Controller (USHC).
Special Features include:
- UL Listed
- Fast Response
- Precise Superheat Control
- Compact and Light Weight Design
- Single Footprint for all capacities
- High Durability and Reliability
- PWM Duty Cycle Control
- Cost Effective Electronic Control
