BVA Hydraulics CVS1 - Manual (Page 2)

PRODUCT DESCRIPTION
BVA Hydraulics Pressure Switch limits pressure developed
by the hydraulic pump, regulating the force imposed on other
components. A wide variety of applications exist for this
category of product. Special skill, knowledge and training may
be required for a specific task and the product may not be
suitable for all the jobs described above. The user ultimately
must make the decision regarding suitability of the product
for any given task and therefore accept responsibility for that
decision.
WARNING: Always wear proper personal protective
gear when operating hydraulic equipment (i.e. safety
glasses, gloves, etc.)
CAUTION: Always check connections before using.
Alteration of these products is strictly prohibited. Use
only those equipment and attachments provided and
approved by the manufacturer.
WARNING: To reduce the risk of personal injury and/or
property damage, ensure that the rated working pressure
of each pressurized attachment be equal to or greater
than the rated working pressure developed by the hy-
draulic pump.

INSTALLATION AND ADJUSTMENT
PUMP MOUNTED INSTALLATION
Mount the pressure switch to the control valve or the manifold
by threading the switch fitting into the port provided for a
pressure gauge. An elbow may be used to change the angle,
and a tee fitting can be used if both a pressure switch and
gauge are required.
PRESSURE REGULATING CONTROL ADJUSTMENTS
The pressure regulating valve can be adjusted to bypass oil
at a specific pressure setting so that the pump will continue
to run. The pressure switch can be adjusted to stop the pump
motor at a specific pressure setting and then restart the pump
when the pressure falls below that setting.
ADJUSTING THE PRESSURE REGULATING VALVE
Adjust the pressure regulating valve by increasing to a
preferred pressure setting. Do not adjust by decreasing from
a higher to a lower pressure.
1. Place pipe plugs in valve ports.
2. Loosen the locknut on the pressure regulating valve. Turn
the adjusting screw a few turns counterclockwise to decrease
the pressure setting to a lower than desired pressure.
3. Connect the pump power supply and place the hydraulic
control valve in the ADVANCE position. Set the motor control
toggle switch to RUN.
4. Slowly turn the adjusting screw in the clockwise direction.
this will gradually increase the pressure setting. When the
preferred setting is reached, lock the adjusting screw in position
by tightnening the locknut.
