Calculate optimal nominal volume, operating pressure and N2 pre-charge using our certified sizing engine.
Open Volume Sizing Calculator →When the system requires stable flow regulation for a liquid—such as cooling water—a stainless steel cooling‑water pressure regulator must be installed in the piping. This regulator stabilizes the system’s water pressure, thereby delivering cooling water at a consistent pressure to the load side.

Direct technical answers from Schwerll fluid power application engineers regarding High-Frequency-Response Servo Valve Damper.
The servo valve damper is engineered to attenuate high-frequency pressure pulsations caused by servo valve movement and accumulator cycling. By damping transient spikes up to 207 MPa, it stabilizes the control loop, reduces strain on components, and ensures accurate response of the accumulator or piston energy storage unit under dynamic load conditions. It is suitable for high-speed switching applications requiring minimal pressure overshoot.
Every Schwerll accumulator is designed, inspected, and validated against international safety and quality standards.
