High-Frequency Servo Valve Damper | Schwerll

Q: How does the high-frequency-response servo valve damper improve stability in a 207 MPa hydraulic accumulator system?

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.

Q: Does SCHWERLL offer custom sizing and certification for servo valve dampers for export applications?

Yes. SCHWERLL manufactures servo valve dampers in accordance with ISO 9001, CE, and ASME standards. Custom connection sizes, pressure ratings, and flow dampening specifications can be provided to meet your OEM or retrofit requirements. Export documentation and material traceability are included. Contact us with your system schematic for sizing calculations and delivery lead times.

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.
