4-Way Reversing Valve DRVB Series
Application
DRVB series change the ow path of refrigerants bycontrolling the action of small DSF valve to switch the mode between cooling and heating.
Features
·X-cross design ensures big ow area and low pressure drop;
·Stability and reliability ensured by adopting a small 4-Way Reversing 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.
