DESCRIPTION
The servo valve is used for flow control and it is a 3 position 4-way valve. This is a two-stage design with R6Z as the torque motor in first stage and the hydraulic assembly as the second stage. The output stage is a closed center with four way sliding spool.
FUNCTION
The valve has a control fork which is closed in center position and operates when a current is given, and a magnetic difference is created. The valve operates with current and comes back to the home position with the help of centering spring on the Torque motor.
APPLICATION
Servo valve is used in HP Bypass system (Main valve and Spray valve)
