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.
