Description

DPF Series EEV are designed for use in air conditioning and refrigeration systems or in heat pumps. The valve controls the automatic adjustment of refrigerant flow rate and makes the system work under optimized conditions for the purpose of fast cooling or heating, precise temperature control and energy saving. The valve can also be used e.g. for suction line pressure controls. These valves provide bidirectional operation to control the refrigerant flow rate in heating or cooling mode.

 

Features:
  • Applicable for reversible systems: Bidirectional Flow.
  • Smaller installation space: Low height, small volume, light weight.
  • Optimized flow path design for noise reduction.
  • Fast operation, energy saving.
