Attention!
Faulty dimensioning of prefill valves and connection lines may lead to cavitation effects. The consequences affect the reliability and durability of products!
Attention!
An underdimensioned prefill valve and/or an underdimensioned line leads to gas leaks from the hydraulic fluid with corresponding consequences and often to long-term damage at the cylinder seals.
Notice!
For limit areas, please contact us. It is often sufficient, to select a pipeline which is one size larger.
