Proportional Directional Valves, Series LVS08 / LVS12
Description
The design uses the concept of pressure compensators integrated in the control spool to achieve very low pressure loss. This feature, together with the downstream system for flexible parallel actuation and the high degree of modularity, makes this proportional directional valve suitable for very adaptable application in mobile machines. The additional functions that can be incorporated, the high power density combined with high actuator flow rates of up to 180 L/min and the possibility of combining two different valve sizes in one control block round off the LVS08 / LVS12 proportional directional valves. They make up a flexible and compact modular valve system.
The valve blocks can be configured for fixed-displacement or load-sensing pump systems.
Proportional Directional Valves, Series LVS18
Description
This range of proportional valves is used to provide load-independent speed control of motors and cylinders. The LVS18 is operating according to the flow sharing principle. Also available with rapid-traverse and floading function.
Proportional Directional Valves, Series SC12 / SC18 / SC22
Description
This range of proportional valves is used to provide load-independent speed control of motors and cylinders.
Proportional Directional Valves, Series SV12 / SV18 and SV25
Description
This range of proportional valves is used to provide load-independent speed control of motors and cylinders.
Proportional Directional Valves, Series SVC25
Description
This range of proportional valves is used to provide load-independent speed control of motors and cylinders.
Proportional Flow-control Cartridge, Series MVRPLSA
Description
The two-stage proportional flow-control cartridge in this series guarantees outstanding load-holding function thanks to leak-free design and load-independent lowering.
The new principle makes it possible to combine several functions in one valve. On the one hand, the leak-free nature is preserved thanks to the ingenious seat design, which shuts off the main and control functions simultaneously and with zero leakage, allowing loads to be held in position for long periods. On the other hand, the integral pressure-compensator function enables responsive, controlled and load-independent lowering.
These unrivalled features are all-important for the economic and convenient handling of loads of all kinds.
Proportional Pressure Control Valves (SB1110 SB1190)
These are closed-loop type pressure control valves controlling the system pressure from low to high in proportion to the input voltage. The stable pressure control is possible even in a small flow rate.
PV2R Series Fixed Displacement Double Vane Pumps
These double pumps consist of two PV2R seires single pumps combined in tandem within a single housing and driven by a common shaft. A Single suction port and two discharge ports are provided so that the output flow can be supplied to separate circuits.
PV2R Series Fixed Displacement Single Vane Pumps
These pumps are high pressure and high performance, which have been developed especially for low noise operation.
To comply with a variety of applications including injection moulding machines, PV2R series single pumps provide the output flow of such a wide range as from 5.8 to 237 cm3/rev (.354 to 14.46 cu.in./rev).
The intergral driving parts of the pumps are combined into a kit form and available for supply as a cartridge kit. Therefore, the replacement of the driving parts can be done easily.
QX Internal Gear Pumps
Description
Pump ‘all-rounders’ up to 400 bar
The QX series is the 5th generation of Bucher’s internal gear pumps and has proven itself for decades in the mobile and industrial hydraulics markets. Many aspects of the design have been enhanced, and it is characterized by a simple layout with relatively few components. It is exceptionally compact and robust. As a direct result of the special gear profile that Bucher uses, QX pumps achieve extremely low levels of pulsation and noise emission, even at high pressures and speeds. Thanks to the wide range of variants, QX pumps can be used for virtually all applications.
QXEM Internal Gear Units
Description
Highly dynamic variable-speed multi-quadrant applications
The QXEM series is intended for operation as both a pump and a motor. A symmetrical design makes these units specially suitable for highly dynamic variable-speed multi-quadrant operation. In the industrial hydraulics field, they are therefore particularly appropriate for applications with highly cyclical loading. Thanks to the pinion-shaft technology, pressures up to 250 bar are built up in a single-stage. The direction of rotation can also be reversed in milliseconds, while maximum operational reliability is ensured at all times thanks to optimized hydrodynamic lubrication.
