The FF-134 series electro-hydraulic servo valve is a linear direct drive flow servo valve with flow rates of 60L/min and 100L/min under a pressure difference of 7MPa. This type of servo valve is directly driven by a linear force motor, without a pilot stage or internal throttling holes. Therefore, it has low leakage, low hydraulic power consumption, strong anti pollution ability, and minimal impact on valve dynamics due to reduced system oil supply pressure. The product uses LVDT valve core position sensors for position closed-loop control, resulting in small hysteresis, high resolution, good repeatability, and high dynamic performance. According to user needs, power-off failure centering or fixed bias can be set to keep the system in a pre-set safe state after unexpected power failure. The control box is designed with an external electrical zero adjustment device, making it more convenient to use. The product shell is made of stainless steel or cast iron, with high structural strength and high pressure resistance. Suitable for steel metallurgy, testing equipment, etc.
