Servo Amplifier Sva Series - Chinaprice: contact company for price
stabilized power supply, mainly for driving and one-stage closed-loop
controlling of nozzle flapper servo valve and jet pipe servo valve, etc.
It uses a portable standalone box, and it is easy to use. The front
board is provided with a potentiometer with a scale locking mechanism
for easy parameter adjustment. An ammeter is used for displaying the
valve’s coil current for easy observation in commissioning. You can
select LVDT demodulation board as necessary for controlling a closed
loop having LVDT detection sensor.
I. Main Features:
Stage-I closed loop controlling of hydraulic servo system
Output current can be up to 100mA, also over current protection is provided
The front board is easy for adjusting such parameters as zero, gain, feedback volume, and disturbance, etc., also an adjustment locking mechanism is provided.
The ammeter on the front board displays the valve’s coil current
With a built in linear DC stabilized circuit. Needs only connecting with AC220V externally.
All the power supply, valve coil and LVDT sensor use independent plug connection, and it is convenient to connect peripherals.

Outline size: 110×225×300 mm
SVA-III-S is a board type electrohydraulic servo amplifier with position demodulator, mainly for controlling 3-stage valve having LVDT position sensor, is of LVDT demodulator circuit, and realizes closed-loop controlling with the inner loop of servo valve’s coil. Moreover, it is of PID controlling for external loop. By different settings of the jumping switch, it can also be used for controlling closed loop of position formed by a 2-stage servo valve and LVDT sensor.

SVA-III-M servo amplifier is a box type amplifier, which is a SVA-III board type amplifier integrated with standard 19-inch power chassis. Its controlling functions are same with that of SVA-III board type amplifier. It is mainly for controlling 3-stage valve with LVDT position sensor, has a LVDT demodulator circuit, and realizes closed-loop controlling with the inner loop of the servo valve’s coil, and is also of PID controlling of outer loop. By different settings of the jumping switch, it can also be used for controlling closed loop of position formed by a 2-stage servo valve and LVDT sensor. It is furnished with an integrated linear power supply. You can supply AC220V directly. It uses a standard casing. The front board ammeter indicates the valve’s coil current for easy observation in commissioning.
Easy and quick front-board testing and adjusting potentiometer
Straightforward valve coil current and power supply indication
Power supply: AC220V
