HYDAC proportional throttle valves for gravity lowering
Your partner for expertise in valve technology for electric drives
Clever energy savings: as the trend toward electric drives in mobile machinery increases, so do the demands on hydraulic components. To achieve a long discharge time with a small battery, all consumers must have the highest level of efficiency. HYDAC relies on leaktight proportional throttle valves that enable energy-efficient gravity lowering. Our valves have stable functions and save energy when lowering loads. Find out now how you too can benefit from this clever solution.

Increasing energy efficiency with electrificationUse HYDAC's expertise to increase the efficiency of electric drives with gravity lowering functions.
Always be a step ahead of the competition and optimize your hydraulic components with the right valve technology! Although electrification leads to progress, it also means high battery costs. With perfectly matched hydraulic components that meet the highest efficiency requirements, you can achieve a long discharge time with a small battery. The challenge is ensuring high handling rates with small pump sizes and minimizing throttle losses in pipes and valves. With our valve solutions for gravity lowering systems (GLS), you can eliminate the disadvantages of counter balance valves prone to losses.
HYDAC valve technology is tailored to your requirementsUse gravity for electrification—save valuable energy with gravity lowering!
Whether it's forklift trucks, elevating work platforms, or telescopic handlers—with the right HYDAC proportional throttle valves, you can save valuable energy by no longer needing hydraulic power when lowering the load. Traditional lowering brake systems require the control pressure for the load holding valves to be applied to the supply side of the cylinder. This has a fundamental disadvantage: when lowering the load, a relatively higher energy input is required at the pump. But this is avoidable with the help of gravity and a gravity lowering system (GLS) that saves valuable energy. Use gravity in a targeted way for your applications and discover our reliable, precise, and efficient valve technology, which is also suitable for systems with electric drives—our experts will be happy to support you in finding the right solution and specification.
The HYDAC solution: proportional throttle valves for systems with a gravity lowering functionPilot-operated leakproof proportional throttle valves from the PWS08Z to PWS16Z series
If you're looking for reliable, precise, and efficient valve technology, then PWS08Z to PWS16Z proportional throttle valves from the PWS series are the perfect choice. Thanks to the additional soft shift option, the valves can be used not only as proportional throttle valves, but also as a soft on/off switching function, without the need for complex proportional control. Our leakproof proportional throttle valves enable operation without a pressure compensator thanks to their stable function even at high differential pressures. With nominal sizes of 8, 10, 12, and 16 and impressive flow rates of up to 200 l/min, the valves are very versatile. Whether it's for gentle connection and disconnection of consumers or precise regulation, the PWS08Z to PWS16Z throttle valves impress with their overlapping and fine control ranges at the poppet as well as with their optional damping orifice in the solenoid armature.
Trust in tried-and-tested technology and rely on the proportional throttle valves from the PWS08Z to PWS16Z series! These valves offer maximum efficiency and precision for electric drives and more.
