Counterbalance valve BVD and BVE

Travel drive/winch counterbalance valves are designed to reduce the danger of overspeeding and cavitation of axial piston motors

in open circuits. Cavitation occurs if the motor speed is greater than it should be for the given input flow while braking, travelling downhill, or lowering a load.

If the inlet pressure drops, the counterbalance spool throttles the return flow and brakes the motor until the inlet pressure returns to approx. 20 bar

BVD available for sizes 28 to 180 and BVE available for sizes 107 to 180

The counterbalance valve must be ordered additionally. We recommend ordering the counterbalance valve and the motor as a set. ordering example

HD-A2FE90/61W - VAB188 + BVD20F27S/41B - V03K16D0400S12

Note

The counterbalance valve does not replace the mechanical service brake and park brake.

Observe the detailed notes on the BVD counterbalance valve and BVE counterbalance valve.

For the design of the brake release valve, we must know for the mechanical park brake the pressure at the start of opening

The volume of the counterbalance spool between minimum stroke (brake closed) and maximum stroke (brake released with 21 bar)

The required closing time for a warm device (oil viscosity approx. 15 mm2/s)

Technical Information

Hydraulic fluid

Before starting project planning, please refer to our data sheets mineral oil and environmentally acceptable hydraulic fluids for detailed information regarding the choice of hydraulic fluid and application conditions.

When using environmentally acceptable hydraulic fluids, the limitations regarding technical data and seals must be observed.

Please contact us. When ordering, indicate the hydraulic fluid that is to be used.

Notes on the choice of hydraulic fluid

In order to select the correct hydraulic fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature.

The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range (nopt), see shaded section of the selection diagram. We recommend to select the higher viscosity grade in each case.

Example: at an ambient temperature of X ℃ the operating temperature is 60℃. In the optimum operating viscosity range (Vopt; shaded area) this corresponds to viscosity grades VG 46 resp. VG 68; VG 68 should be selected.

Important

The case drain temperature is influenced by pressure and input speed and is always higher than the reservoir temperature.

However, at no point in the component may the temperature exceed 90℃. The temperature difference specified on the left is to be taken into account when determining the viscosity in the bearing

If the above conditions cannot be met, due to extreme operating parameters please contact us.

Filtration of the hydraulic fluid

The finer the filtration the better the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit.

In order to guarantee the functional reliability of the axial piston unit it is necessary to carry out a gravimetric evaluation of the hydraulic fluid to determine the particle contamination and the cleanliness level according to ISO 4406.

A cleanliness level of at least 20/18/15 must be maintained.

At very high hydraulic fluid temperatures (90℃ to maximum 115℃), a cleanliness level of at least 19/17/14 according to ISO 4406 is necessary.

If the above cleanliness levels cannot be maintained, contact us.

General instructions

The pump HD-A2FO is designed to be used in open circuits. The motor HD-A2FM/E is designed to be used in open and closedcircuits.

The project planning, installation and commissioning of the axial piston unit requires the involvement of qualified personnel.

Before using the axial piston unit, please read the corresponding instruction manual completely and thoroughly.

During and shortly after operation, there is a risk of burns on the axial piston unit. Take appropriate safety measures (e.g. by wearing protective clothing).

Depending on the operating conditions of the axial piston unit (operating pressure, fluid temperature), the characteristic may shift.

Service line ports

The ports and fastening threads are designed for the specified maximum pressure.

The machine or system manufacturer must ensure that the connecting elements and lines correspond to the specified application conditions (pressure, flow, hydraulic fluid, temperature) with the necessary safety factors.

The service line ports and function ports can only be used to accommodate hydraulic lines.

The data and notes contained herein must be adhered to.

The product is not approved as a component for the safety concept of a general machine according to ISO 13849.

The following tightening torques apply

Fittings

Observe the manufacturer's instructions regarding tightening torques of the fittings used

Mounting bolts

For mounting bolts with metric ISO thread according to DIN 13 or with thread according to ASME B1.1, we recommend checking the tightening torque in individual cases in accordance with VDI 2230.

Female threads in the axial piston unit

The maximum permissible tightening torques MG max are maximum values for the female threads and must not be exceeded. For values, see the following table.

Threaded plugs

For the metallic threaded plugs supplied with the axial piston unit, the required tightening torques of threaded plugs MV apply. For values, see the following table.
