The RANCO 4-Way Reversing Valve, when installed in a heat pump system, reverses the direction of refrigerant flow through the heat exchanger coils to provide heating or cooling from the system and to provide for defrosting of the outdoor coil in air source units. It is designed for residential and commercial heat pumps (unitary and split systems), including air and water heat sources.

  • Designed for minimal pressure drop to allow higher system efficiencies.
  • 4-way pilot valve uses high and low side refrigerant pressure to push and pull the main valve slide for positive reversals at low pressure differentials.
  • Hermetic construction using high quality materials (brass, copper, stainless steel) to eliminate external leakage for longer system life
  • Teflon® lubricated sliding surfaces provide reduced internal friction and high contaminant resistance to provide longer valve durability and reliability (V4?V12).
  • Low solenoid power consumption provides a Class B UL thermal rating for AC coils.
  • Solenoid coils have 1/4 male quick connects and are color coded by voltage.
  • Solenoid coils can be removed within the length of the valve body and can be shipped attached to the valve in a choice of 4 positions.
  • Available W29 wiring harnesses are shipped separately.
  • Wiring harnesses can be specified at various lengths, terminations, and identification.
