The Sporlan SEH series consists of electronically operated step motor expansion valves designed for precise refrigerant flow control in large-capacity air conditioning and refrigeration systems. They are the largest valves in the Sporlan EEV family, offering exceptional resolution for maintaining stable superheat even under widely varying operating conditions.

Key Features

• Large Capacity: Specifically designed for high-capacity applications, such as large chillers and air-cooled systems, with models like the SHE-P.
•  being the largest approved for air-cooled R-410A use.
• Tight Seating: Provides solenoid-quality tight shut-off to prevent refrigerant migration during the off-cycle.
• Built-in Sight glass: Integrated into the SEHImodels, this feature allows technicians to monitor moisture levels, refrigerant quality, and witness actual piston movement for diagnostics.
• Compatibility: Suitable for use with all common HCFC and HFC refrigerants(including R-410A) and subcritical CO2.
