电动调节阀阀体材料主要有青铜、铸钢两种类型。执行器为24V，反馈信号为0-10V或4-20mA，增量及调节量两种控制方法。
1．应用
HY-VA3000系列阀门驱动器适用于本公司小规格的各系列阀门，它以交流单相AC24V为电源，可接收控制信号为比例三浮点（双开关量）、比例调节模拟量（0-10VDC、4-20mADC）及浮点电压反馈等各种控制器的控制。根据调节阀口径及关断压差选择驱动力，同时还可以与其它厂家的调节阀阀体相互匹配。执行器设计有伺服系统（电子定位器），只需直接接入DC4 ~ 20mA、DC0~10V或自行预设的直流控制信号即可工作。
2．特点：
2.1选用合金铸铝支架，强度高、重量轻
2.2调整简单，便于操作
2.3阀门定位准确
2.4同步电机，低功耗
2.5高关断输出压力
2.6多种输入控制信号选择，可通过状态选择开关选择标准（DC4～20mA或DC0～10V）或非标准（自行设置）控制信号
2.7正反作用可选
2.8具备自适应功能，一键设定不同口径、不同行程阀门的零位和满位
2.9用状态选择开关可以设定断信号时，阀芯处于全开，全闭或保持状态。
2.10分辨率高，并可通过按键设置，最高可达到0.4％的控制精度
2.11三重保护功能，通过机械、电路及软件均能起到保护作用，避免对执行器本身的伤害
2.12具有机械手动和电子手动功能，可使操作更方便
2.13过载报警，当发生过载阻转时，定位器指示灯会立即闪烁并发出无源接点信号报警。
Electric control valve body materials are bronze, cast two types.Actuator to 24V, 0-10V feedback signal, or 4-20mA, incremental, and adjust the volume of two control methods.
1.Applications
HY-VA3000 series valve drive specifications applicable to the Company's various series of small valves, it AC24V to AC single phase power, control signals can be received as a proportion of the three floating point (double switch), analog proportional control (0 -10VDC ,4-20mADC) and other floating-point controller voltage feedback control.Under the control valve off caliber and selection pressure driving force, but also with other manufacturers of control valve body match.Design of a servo actuator system (electronic positioning device), only direct access DC4 ~ 20mA, DC0 ~ 10V DC or on its own preset control signal to work.
2.Features:
2.1 The selection of cast aluminum alloy frame, high strength, light weight
2.2 The adjustment is simple, easy to operate
2.3 The valve positioning accuracy
2.4 Synchronous motor, low power consumption
2.5 high output pressure off
Select more than 2.6 kinds of input control signals, through the state selection switch selection criteria (DC4 ~ 20mA or DC0 ~ 10V) or non-standard (self-setting) control signal
2.7 Optional positive and negative effects
2.8 with adaptive function, a key set of different calibres, different stroke of the valve position zero and full
2.9 can be set with the state selection switch off the signal, the spool is fully open, fully closed or on hold.
2.10 high resolution, and through key settings, up to 0.4% of the control accuracy
2.11 triple protection, by mechanical, circuit and software can play a protective role, to avoid damage to the actuator itself
2.12 with a mechanical manual and electronic manual functions, make the operation more convenient
2.13 overload alarm, when the transfer occurred when the load resistance, the Locator indicator light flashes and immediately issued a passive contact signal alarm.
