For consistent machine operation, Vickers by Danfoss servo valves provide closed-loop control with exact positioning, repeatable velocity profiles, and predictable force or torque regulation. At pressures up to 350 bar [5,000 psi] and flows up to 151 l/min [40 US gal/min], the symmetric designs enable dependable control-flow metering, minimal null shift, and frequency response over 100 Hz with a 90-degree phase lag.
