Product Description

The SDA20*70 electric actuator is a compact linear drive designed for precise control of valves in industrial automation systems. Featuring a 20mm stroke, this valve actuator operates within a wide voltage range of 12-24V DC and supports both analog (4-20mA) and digital (PWM) input signals. It directly interfaces with PLC modules through RS-485/Modbus communication, offering seamless integration with control systems. With an operating temperature range of -20°C to +70°C, it is ideal for HVAC, water treatment, and process control applications. The actuator's IP67-rated housing ensures durability in harsh environments. Key advantages include zero-backlash mechanics and maintenance-free operation, though the fixed 20mm stroke limits flexibility for varied stroke requirements. Built-in position feedback provides accurate stroke monitoring, while its compact 70mm length enables installation in space-constrained environments.
