Product Description

The FF-638M series electro-Hydraulic Servo Valve is a linear direct drive flow Servo Proportional Valve with a flow range of 50L/min and 100L/min under a pressure difference of 7MPa. This type of Servo Valve is directly driven by a proportional solenoid, without a pilot stage or internal throttling holes, resulting in low leakage, low hydraulic power consumption, strong anti pollution ability, and minimal impact on valve dynamics due to reduced system oil supply pressure. The LVDT valve core position sensor is used internally for position closed-loop control, resulting in small hysteresis, high resolution, and good repeatability accuracy. Compared to general servo valves, this series of products has multiple power-off safety position functions to choose from, which can keep the system in a 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. It is widely used in heavy machinery, steel, metallurgical industries, as well as blowing and injection molding machines.

Operating Principle:

When a certain control signal is input to the control terminal of the valve, it is amplified by a digital amplifier to generate a corresponding driving current that acts on the proportional electromagnet. The proportional electromagnet generates driving force, which drives the displacement of the valve core and ultimately balances with the spring force and the hydraulic force of the valve core. The spool displacement sensor feeds back the position signal of the spool to the digital amplifier, forming a position closed-loop control, so that the spool displacement (i.e. valve flow) is proportional to the input signal.
