The Bayne diverter valve establishes priority flow to the lifter circuit “P1” and “P2” ports and
bypasses oil to the “OUT” port, which typically supplies flow to the remainder of the truck’s
hydraulic circuit. This bypass occurs only after the lifter circuit is satisfied. The priority flow
is controlled by the flow regulator cartridge (FR1) (and FR2 in dual applications) in
combination with the differential pressure sensing valve (DPS). This allows the valve to
maintain constant flow regardless of changes in load pressure or volume flow rate. Since both
the lifter circuit and bypass flow can be utilized in the operation of the truck regardless of
which pressure is greater, a single pump can be used to supply two circuits or operations.
The lifter circuit flow is regulated and maintained by the flow regulator cartridge (FR1) (and
FR2 in dual applications). The differential pressure sensing valve (DPS), rated for 75 gpm of
flow and 3000 psi of pressure, is operated by an internal spring and dampening orifice (OR)
which establishes a pressure drop across the block sufficient to ensure the correct operation of
the flow regulator (FR1). For a dual diverter valve, a second flow regulator cartridge (FR2) is
installed in the “FR2” cavity and a shuttle valve (DSV) is installed in place of the SAE plug in
the “DSV” cavity. Once the pressure drop is established, a precision metered flow is provided
to the tipper circuit(s) with additional flow being bypassed to the “OUT” port.
The operation of the diverter valve does not require the use of a tank line to be run to the “T”
port. However, the efficiency of the block will be significantly increased if a tank line is
installed. The logic circuit of the block will manage the flow of oil returning from the tipper
circuit to ensure optimum performance. This is primarily controlled with the sequence valve
(PSV) which is factory set and should not be adjusted. All oil returning from the tipper circuit
will normally be regenerated into the outgoing flow to ensure that the downstream functions
are not slowed in any way. When the downstream backpressure rises to a predetermined
pressure, the block will redirect the flow to the “T” port to increase the overall efficiency of
the block and reduce the pressure drop through the block. If the “T” port is connected to a
tank line, the oil will be dumped through the block at a lower pressure. This allows
downstream functions to operate at the highest possible pressure when pressure is being
required. If the “T” port is blocked, the oil will be redirected back into the outgoing flow
through the check valve (CV).
A relief circuit for the tipper function is controlled by a relief valve (RV), which is preset to
2300 psi. This can be adjusted to limit pressure to the tipper(s). This relief valve is more
efficient than the relief in the hand valve and will operate with less noise. It is recommended
that it be adjusted to relieve before the hand valve relief. It may also be used to limit the
weight the lifter can dump. This may be beneficial in avoiding damage to cans resulting from
overloading. This should be the only adjustment that the block may require. Any other
adjustments should only be made after close consultation with Bayne’s Engineering
Department to ensure proper operation.
