Enterprise profile

Starting the research and development of electro-hydraulic servo valves (EHSV in short) in 1968, AVIC Nanjing Servo Control System Co., Ltd. is an industrial base of EHSV with leading technical capability in China. Our company is mainly engaged in the R&D, manufacturing, test and repairs of EHSV and also has the ability to develop servo systems and non-standard equipment for industrial application.

We have staff of over 200 people with 29 of them being engineers and 51 being senior technicians. We have over 300 sets of equipment and machines, with fixed assets valued at USD 25 million. We are the only one in China to carry out performance test and environment test and validation with working fluid of mineral based hydraulic fuel, phosphate fuel and fuel.

Our EHSV are widely used in aeronautics, space, navigation, metallurgy, machine manufacture, geological exploration, construction machines and all kinds of test equipment. In aeronautics applications, EHSV are used in rudder actuation system, front wheel control system, inlet control system, electronic anti-skid system, radar servo system, cargo door retraction system, engine digital control system, APS and APU.

Our product line covers over 200 models, including force-feedback single stage servo valve, nozzle-flapper two stage servo valve, jet pipe EHSV ( jet pipe and jet deflector type ), DDV and RDDV, combined control valve, electro-magnetic hydraulic lock, pressure-reducing valve, hydraulic pump, servo amplifier and EHSV static and dynamic test bench. EHSV’s working fluid covers mineral based hydraulic fuel, phosphate fuel and fuel.

We are also the national leader in terms of EHSV performance test and environment test and validation using hydraulic fluid and fuel. Our test bench includes static and dynamic test, high and low temperature, vibration and shock, temperature-altitude environment test. Temperature test bench can go as far as fluid temperature: -55℃~+150℃, environment temperature: -55℃~+250℃.
Now we have setting 2 national military standards and one industrial standard. We have 28 technical patents covering EHSV design, measurement and process and test method for whole valve and parts. We also have state of art equipment for hydraulic grinding, deburring etc.

AVIC Nanjing Servo Control System Co., Ltd. boasts itself in its complete quality management system, advanced manufacture and development level. We are the national leader working towards the digitization, intelligenzation and high pressuration of EHSV. We will strive to keep our clients happy.
