Monoblock valves with integrated pressure compensated flow control
BF Series (patented)
The monoblock valves of the BF
series deriving from
the valves of the BM series differ from them by having at the inlet
a three ways priority integrated and pressure compensated flow control (RFP) or
two ways integrated pressure compensated flow control (RFS)
. In the RFP
type the exceeding flow is recuperated into the system and allows the simultaneous
use of the two sections of the valve, the first ruled by the priority (PF
and the second by the exceeding flow (EF
). In the RFS type the exceeding
) goes to tank. A very important feature is that the
flow control only works when a priority element is actuated.
On the contrary
the oil goes to tank without the flow control being actuated and, therefore, without losses
of flow and unnecessary heating.
In RFS circuits, non-priority sections get the whole flow when they are individually
operated; in RFP circuits, when a priority section is actuated, non-priority sections
get only the exceeding flow.
BF valves are available with One or more priority elements.
