New Products and
Applications:
LEFC – Large
Electric Flow Control
The Brand, LEFC (large
electronically adjustable proportional pressure compensated flow control) is an
electronically controlled version of the original large FC51 style flow control
valve. The LEFC performance as a flow
control is very similar to the large FC51 because they both use the same spring
and compensator spool. Thus, the
control flow port (CF) and the excess flow port (EX) remain usable and pressure
compensated.
Going
from Manual to Electric
Problem: Brand’s manual FC51-16SAE currently controls the
speed of a hydraulic motor that throws fertilizer a certain distance. To maintain the fertilizer distance the FC
must be adjusted periodically throughout the day. Right now, the truck has to be stopped so that the FC on the back
of the truck can be adjusted to the correct fertilizer distance. The down time, from stopping the truck,
increases the time to fertilize a field.
Solution: Use Brand’s LEFC164512L in conjunction with an EC-12-01
or EC-12-02. The customer no longer has
down time because now the fertilizer distance can be adjusted while the vehicle
is being driven.
SB4 – Non-Adjustable Divider
Combiner Valve
The valve receives a single stream of fluid and
divides it into two equal streams regardless of the pressure differential. When flow is passed through the valve in the
opposite direction, it receives the two streams and evenly combines them into
one stream. Better accuracy is achieved
when the orifices are sized to the specific input flow.
Synchronizing
Trash Bin Cover
Problem: State law requires trash dumpsters to be covered
when they are transported to county landfills.
One-way to do this is to have two arms, controlled by double acting
cylinders, unroll a tarp from the front of the dumpster to the back of the
dumpster. The problem is that the
cylinders do not extend and retract at the same rate, causing damage to the
mechanical apparatus.
Solution:
The extension and retraction of both cylinders can be controlled with
Brand’s new divider combiner. This
valve eliminates damage to the mechanical apparatus, thus reducing repair
costs.
EC –Custom
Electronic Package
Brand Hydraulics can produce custom electronic
turnkey packages. These packages can be
from simple switch boxes to complex proportional control-units. They can include controls, cables,
enclosures, wiring harness and hydraulic valves. Let Brand Hydraulics be your single source for electronic control
packages and hydraulic valves.
Mobile Beach
Cleaner
Problem: A mobile beach cleaner is a piece of equipment
pulled behind a tractor. The piece of
equipment sifts the sand to remove any types of impurities. The cleaner has motors and cylinders that
need to be proportionally controlled from the cab of the tractor.
Solution: Brand Hydraulics chose to use a handheld control
with a proportional controller and multiple switches. The cable on the handheld control has a circular connector for
easy removal. A proportional controller
will control the speed of the hydraulic motor using Brand’s EFC (Electronic
Flow Control), while the switches control the cylinder functions using Brand’s
Series 36 (Electronic Stack Valve).
Cable lengths and connector locations were also designed to the
manufacturers specifications. This
allows the customer to install the package right out of the box.
Grain
Harvester Improvement
Problem: A piece of agricultural equipment, with a spinning
reel, needs to maintain a ratio between the spinning reel and vehicle
speed. Right now, the reel speed
remains constant as the vehicle speeds up and slows down. This causes loss or destruction of grain,
thus causing a loss in profit.
Solution: Brand Hydraulics designed a package that uses a
sensor to measure the ground speed. The
signal from the sensor is feed into a custom electronic controller. The electronic controller has adjustable
gains so the reel can be adjusted for initial setup and different situations.
This allows the reel speed to automatically adjust, at a preset ratio, to
changes in vehicle speed.
Product Modifications, Additions and Changes:
Horizontal Hand Pump
Brand has modified the standard hand pump so that it can
now be mounted horizontally. The foot
brackets are made from 1/4” steel so that the pump can be mounted rigidly to
any flat surface. Four tie rods are
used to retain the foot brackets to the tank and casting. The foot bracket, which seals against the
tank, incorporates an o-ring seal to eliminate external leakage. Air is now vented through a hole on the vent
plug, instead of the notch on the tank.
Brand feels that these features create one of the most durable and
competitive horizontal hand pumps on the market.
Forty
gpm Relief Valve
In the past year, Brand added a manifold type relief to its
current line of RL’s. The new RLC (high
lift ball spring type) is designed for applications where the customer may need
high flow capabilities, less chatter and/or less noise. The RLC can be ordered with either #12 or
#16 SAE porting. The advantage of the
RLC over the RL is that it virtually maintains the same relief pressure from
crack open to full flow. The flow and
pressure rating is 40 gpm and 3000 psi respectively. It can be ordered under the following model codes RLC16-1500 or
RLC12-1500.
RLC
– Example of Common Model Codes
RLC12-1500….High
lift ball spring relief type, #12 SAE ports, rated
for 30-gpm and 1500 psi relief
setting.
RLC16-2000….High
lift ball spring relief type, #16 SAE ports, rated
for 40-gpm and 2000 psi relief
setting.
SERIES 34 JOYSTICK
OPTION
The Brand joystick handle kit may only be used on
two adjacent spool sections in a valve assembly. Both of the spool sections must have the “A” call out in the
sections model code, which designates that it is machined for the joystick
option. The joystick handle assembly
can be used on high spool sections with reliefs, double locks and with fourth
position float. The call out for the
handle kit is “34HA”.
SERIES 34 HANDLE UPDATE
Brand’s
handles are changing to increase durability, simplify design and reduce the
amount of play. The handle kits that
are being replaced are 34HX, 34HXA, 34HXAS and 34HXS. All of the model codes with an “X” will be switched to a “B”. Example: 34BFT4SX changes to 34BFT4SB. Assembly numbers with the “X” style handle will
be given a new assembly number with the “B” style handle. The 34HG and 34HGS is an additional handle
option for low, relief and double lock sections. Brand has been shipping valves with the new handle design since
September of 2001.
34HB
NEW HANDLE KITS
34HB Bent handle used for low spool sections
34HBS Straight handle used for low spool sections
34HG Bent handle, age-hardened aluminum extrusion and
used with all spool sections.
34HGS Straight handle, age-hardened aluminum extrusion and
used with all spool sections.
