4-Way Reversing Valve DRVB Series


Application

DRVB series change the flow path of refrigerants by controlling the action of small DSF valve to switch the mode between cooling and heating.


Features

  • X-cross design ensures big flow area and low pressure drop;

  • Stability and reliability ensured by adopting a small 4-way valve as the pilot valve;

  • Flange construction makes assembly and maintenance easy;

  • Built–in self-lubricating bush;

  • Special material of seal ring ensures the valve's applicability to all common refrigerants.
