Web3.1 Servo-valve A servo-valve (Figure 4) consists of a torque motor and a sliding spool, which is positioned by a torque motor. The volume flow rate QV of the fluid (hydraulic oil) is controlled by the voltage uinon the torque motor. In the neutral (Zero) position uin = 0, the two output ports are at the same energy level (balanced position). WebOct 15, 2010 · Servovalve Circuits. When a cylinder or fluid motor application needs precise control of position, speed, or force, an on/off solenoid or proportional solenoid valve will not do the job. Some rolling mills control metal thickness to a tolerance of ±0.0005 in. This is with metal passing through the rolls at 2500 to 3000 ft/min and more.
WebSERVO VALVE CONSTRUCTION A servo valve is a precisely machined spool-type directional control valve with some type of actuator to control the spool position. A torque motor can be used with a hydraulic cylinder to move the spool, rather than a solenoid mounted at the end of the spool. SERVO VALVE CONSTRUCTION Three types of servo-valves.
WebJun 8, 2009 · Use proportional control valves to reduce shock and give a finer degree of control to circuits that do not require extreme position accuracy, or repeatable speed and force. Proportional valves restrict flow to and from an actuator.
