NG 6 intermediate plates with pressure control valves and bypass valves from HAWE
HAWE Hydraulik SE, Munich, has developed additional versions of its intermediate plate, type NZP, with the hole pattern NG 6, thereby pursuing its strategy of offering components with tried and tested HAWE technology and hole patterns that conform with industry standards.
Newly added are versions for pressure control valves of the types CDK and CLK. Both these types are built as directional seated valves, which means that they are leakproof when closed. The CLK pressure control valve has an additional safety valve function so it can be integrated into clamping circuits that are pressurized for an extended period of time and subjected to the unwanted pressure increases due to temperature oscillations. The valve is equally well suited for systems in which processing forces or other external factors can trigger inadmissible high pressure peaks. The combination of the NZP intermediate plate with pressure control valves was devised to withstand operating pressures of up to 500 bar and a volume flow of up to 22 l/min.
Further new versions are realized by combining the intermediate plate with directional seated bypass valves. These arrangements connect the hydro consumer and/or the return at volume flows of up to 20 l/min and operating pressure of up to 400 bar, depending on the dimension of the solenoid. Other versions with energy-saving 8-Watt solenoids are also available.
The combination of intermediate plates and drain valves can be used to relieve consumers that are shut with zero-leakage directional seated valves.
Intermediate plates enable the flexible and straightforward assembly of hydraulic controls. Already existing intermediate plate versions can be combined with throttle valves and restrictor check valves as well as proportional pressure valves.

Sauer-Danfoss launches H1 Bent Axis Motor
Sauer-Danfoss launches H1 Bent Axis Motor
The new H1 bent axis motor joins the successful H1 family, providing further improvements in efficiency, reliability, and flexibility.
NORDBORG, Denmark, Sauernfoss Inc. (NYSE:SHS) Sauer-Danfoss has released its new H1 60cm3 bent axis motor, the next size in a series of motors designed to complement the growing range of H1 axial piston pumps. With the introduction of the H1 bent axis motors, Sauer-Danfoss offers a complete H1 transmission system, optimized around electrical control. The H1 motors not only provide OEMs with improvements in reliability and flexibility, but also provide higher overall efficiency, resulting in lower fuel consumption and reduced life cycle costs. Typical applications that will benefit from the new H1 bent axis 60cmm motor are rough terrain forklifts, combines, sprayers, road rollers, wheel loaders and road building equipment.
The new H1 bent axis variable displacement motors have been designed to ensure outstanding reliability and high quality. Optimized for electrical control, they are fully PLUS+1TM Compliant, enabling seamless integration with Sauer-Danfosss electronic machine control architecture. To withstand the harshest working environments, the electrical controls are designed with an IP67 and IP69K rating. The H1 60cmm bent axis motor is an evolution of proven technologies centered on a high displacement ratio of 32 degrees, zero degree capability, and higher overall efficiency. This combination provides a unique range of benefits that fit any OEMMs requirements for machine design.
High Efficiency
An extensive simulation and testing program for the H1 bent axis motors has resulted in significant improvements in overall efficiency and an extremely low pressure drop within the fluid galleries of the motor. The H1 bent axis motors have a 6 percent efficiency gain at maximum displacement (high torque working cycle), compared to the nearest competitor.
Zero Degree Capability
A key feature of the new H1 motors is their zero degree capability. It provides for seamless 'on the go' shifting from 32 to zero degrees, such as in wheel assist applications, providing for a smooth transition with little or no torque interruptions or sudden speed changes. This enhanced control is not only more precise, but also improves the feel of the system during operation. The H1 motor will also shift seamlessly between two speed ranges, for example, work mode and travel mode, regardless of displacement settings. The value that zero degree capability brings to the customer is the flexibility in design to meet many machine operating conditions,, says Horvat. It enables OEMs to offer additional features, such as anti-slip functionality and torque control, which optimize the use of available power and improve productivity..
Optimized for Electrical Control
Energy conservation and functional safety (Safety Integrity Level SIL) is driving the demand for electronic engine management and vehicle control for off-road mobile machinery. As such, H1 bent axis motors have been designed around electrical controls, which allow a range of vehicle control concepts to be produced using the same motor hardware. With electronic control, the H1 system can be optimized to match the requirements of specific vehicle functions by adjusting the software parameters.
Designed for Quality and Reliability
H1 motors have been developed around a common design concept, in order to ensure outstanding motor performance. This design commonality provides improvements in quality and reliability at the factory level and leads to benefits of uniformity and familiarity at the OEM level, supporting standardized machine design.
The H1 motors have the shortest length of any motor available on the market today, and at least one clean sidee, increasing vehicle design flexibility and facilitating installation. The higher speed capability of the motors also results in a high corner power and power density. This provides more power without increasing the size of the motors, which not only saves additional space, but also enables OEMs to design more compact system solutions.

Eaton releases new 420 Series Piston Pumps with Hydro-mechanical Torque Control
Eatonns 420 Series Piston Pumps with Hydro-mechanical Torque Control
Help Compact Equipment Users Meet Emissions, Fuel Economy Standards
EDEN PRAIRIE, Minn. . . . Diversified industrial manufacturer Eaton Corporation has added a hydro-mechanical torque control option and several performance upgrades to its 420 open circuit piston pump product line. The 420 pump with hydro-mechanical torque control automatically senses heavy loads and adjusts hydraulic fluid flow accordingly.
It is intended for moderate-flow, high-pressure mobile applications such as compact wheel loaders, telehandlers, rough terrain forklifts, telescopic booms, sweepers, backhoe loaders, and garbage trucks.
To accommodate the new torque control, the pump housing was designed to decrease airborne noise to 76 dBA at 1,800 rpm and 207 bar. A case-to-inlet check valve \ was added to improve cold weather operation and provide added protection to the seals and rotating group. The new torque control works in parallel with the standard compensator, using a special mechanism to replace the control piston.
In compact and mid-size equipment, torque almost always needs to be controlled,, said Eaton Product Manager Todd McIntyre. Limiting the torque at the pump shaft across a wide range of engine speeds provides operators with the benefits of increased productivity, greater efficiency and fewer engine stalls. The result is lower engine emissions and improved fuel economy.
Productivity is enhanced by increasing the speed with which the vehicle function is performed due to flow rate changes made by the torque control system. For example, raising a heavy load with a set of forks on a telehandler places a significant amount of pressure on the hydraulic pump and system. To prevent engine stalls without limiting the telehandlerrs lifting capacity, manufacturers not using torque control would be forced to use a smaller displacement pump that significantly slows the operation of the forks. Torque control automatically senses heavy loads and adjusts flow accordingly. Limiting the flow in high pressure situations limits the torque the pump can apply to the engine and, as a result, avoids the corner horsepower point and prevents the engine from stalling. It also allows for higher flow and quicker operation when the set of forks is empty, which means higher productivity..
Eatonns 420 pumps offer outstanding power density that is not compromised by the use of torque control.
