Introduction
DSF4-way
Reversing
Valve is the
component to
provide
heating and
cooling from
the system
to the
conditioned
space by
reversing
the flowing
direction of
refrigerant,
which is
used at room
air
conditioners,
packaged and
central air
conditioners.
Our
reversing
valves are
designed for
heat-pump
systems with
the capacity
from 0.75PH
to 15PH;
they are
suitable for
most
refrigerants
such as
R22,R134a,R407C,
and R410A.
