Biflow valves for OEM use are equipped with an unipolar stepper motor drive. They are mainly used for heat pumps, air conditioning and close control.
Features and benefits
• Capacity: 1.6 ~ 2.7kW • Unipolar stepper motor
• Bi-flow (same performance in both flow directions in term of capacity)
• High MOPD: 40 bar in normal flow direction
• Removable coils in two versions: 12 VDC/24 VDC
• Continuous modulation of mass flow, no stress (liquid hammering) in the refrigeration circuit
• Linear flow
• Resolution: 500 pulses (half steps) or 250 full steps
• Hermetic design
• Reliability: 225 millions pulses at continuous 40 bar differential pressure
• VDE tested according to IEC-60335-2-89 and IEC-60335-2-40
