• A hydraulically piloted 2- or 3-stage valve for closed-loop control of force, position, pressure or velocity.
• The pressure chamber on the control valve sleeve is designed with a gap seal, with no seal ring wearing.
• Sound sensitivity, good rapidity, high dynamic characteristics, low hysteresis and zero drift.
• Mainly used for pressure, flow or position control in hydraulic servo control systems.
• The most important actuator element in the electro-hydraulic control system, applied for low pressure.
• Rotary valve core and clearance adjustment structure, small friction loss, high repetition accuracy.
• External manual mechanical adjustment, performance monitoring and online clean without disassembly.
• For high precision control cases such as strip centering and correction of electro-hydraulic control system.
• Core element of servo system control for electro-hydraulic signal conversion and hydraulic amplification.
• It can convert the low-power electrical input signal into high-power hydraulic energy output.
• Compact structure, fast dynamic response, high control precision, long service life.
• Suitable for position, speed, acceleration, force (or pressure) servo control system.
