Features
Electro-hydraulic servo valve is the core element of electro-hydraulic servo system control. It connects the electrical part with the hydraulic part to realize the electro-hydraulic signal conversion and hydraulic amplification, adopts dry torque motor and 2 stage hydraulic amplifier design with high sensitivity, good rapidity and large magnification, and can convert low-power electrical input signal into high-power hydraulic output. It stands out for compact structure, fast dynamic response, high control precision and long service life, etc. It is widely used in electro-hydraulic servo control systems of aviation, metallurgy, chemical and other industries.
