ADCA LINEAR ELECTRIC ACTUATORS AVF234S and AVM234S

ADCA linear electric actuators AVF234S and AVM234S

Product foundation and core positioning

Product model: ADCA brand AVM234S, AVF234S linear electric actuators, are valve specific drive equipment produced by VALSTEAM ADCA in accordance with the reasonable engineering specifications of the EU PED pressure equipment directive.

Core advantages: The AVF234S has the characteristics of automatic valve stroke adaptation, precise driving, high energy efficiency, and low operating noise. In addition, it has a fault safety function of spring reset.

Adaptation scenario: Ideal for use in DSH series direct steam jet humidifiers, VCP drain valves for TDS (total dissolved solids) control systems, and can also drive V series ADCATrol control valves. Other valves can be adapted as needed.

Core functional characteristics

Protection and Safety

Protection level up to IP66 (EN 60529), protection category III (IEC 60730), overvoltage category III, pollution level III;

AVF234S exclusive spring reset fault safety: In case of power outage/power interruption, the spring is driven to the fault safety position (with the thrust rod extended), and the spring reset times are * *>40000 times * *;

Under modulation conditions, terminal position sealing is achieved through limit switches.

Control and regulation

Support automatic detection of control signals and equipped with LED signal indicators;

Input types: switch input (2-point/3-point stepper control), analog input (0... 10 V or 4... 20 mA);

The characteristic curve (linear, quadratic, equal percentage) and motor operating time/speed can be adjusted through DIP switches to meet different valve control requirements.

Operation and Instruction

Support manual operation, capable of disconnecting the actuator motor and adapting to on-site emergency operations;

Equipped with mechanical stroke indicator, visually view the valve drive stroke status.
