MOOG servo valve d634-341c/r40ko2m0nss2

​MOOG Servo valve D634-341C/R40KO2M0NSS2 It can be used for tee 、 Cross and 2×2 Throttling flow control valve with the a through , It is mainly used for electrohydraulic positioning 、 Speed 、 Pressure or force control systems and other systems requiring high dynamics , The valve has an internal integrated circuit board , Closed loop control and pulse modulation drive circuit .

Advantages of features

• Pressure does not affect dynamic performance .

• No pilot oil source is required .

• In case of power failure or cable damage or emergency shutdown , The valve core does not need to use external force to automatically return to the spring centering position .

• Low hysteresis , high resolution .

• It is a servo valve with valve core position feedback function .

• Electrical zero adjustment .

• The valve inner plate includes a pulse modulation (PWM) And a circuit for driving the position of the control valve core of the linear force motor .

function

1. valve A and B Flow control port ( Throttle control )

2. Can be used with 1.5% One 3% or 10% Positive coverage of the axial opening spool .

3. When used for tee , Valve port A or B The end should be blocked .

4. When the valve port T pressure P>5Mpa when , Valve port Y The valve port must be closed Y Connect back to the oil tank .

Be careful ：

1. The valve is a throttling control device , When the position of the valve core is constant and the pressure drop at the throttle port changes ( For example, due to the change of oil viscosity , System pressure or load pressure changes and other factors ), The load flow of the valve will change .

2. Before the installation , The hydraulic system must be cleaned .

3. In addition, be sure to refer to the sample materials for electrical precautions .
