Product Description
D633 and D634 series are direct acting valves (DDV) with closed-loop position control of live feedback valve core. This valve is athrottle type flow control valve which can be applied to three-way, four-way and 2x2-way valves. They are suitable for electro-hydraulic position, velocity, pressure or force control systems and other systems requiring high dynamic response. The valve core is driven by a permanent magnet linear force motor, which can flexibly drive the valve core from the spring centering position in two directions. This is one of the advantages of the proportional solenoid valve, which can only produce one-way driving force. A closed-loop valve position control circuit board and a pulse width modulation (PWM) driving circuit are integrated in the valve. The integrated circuit of the valve is a great development characterized by SMD technology with PWM current drive output and 24V power supply.
Advantages of direct acting servo valve:
——Directly driven by permanent magnet linear force motor with high driving power
——No pilot oil source required
——Dynamic performance is not affected by pressure
——Low hysteresis and high resolution
——Low power consumption at and near hydraulic zero
——The standardized valve core position detection signal can be used to obtain the operation of the system and is very beneficial
to the maintenance of the valve
——The standardized valve core position detection signal can be used to obtain the operation of the system and is very beneficial
to the maintenance of the valve
——Electrical zero adjustment
——In case of power failure or cable damage or emergency stop, the valve core will automatically return to its spring centering position without external force.
