SD-3000 + LTU Series
SD-3000 + LTU Series
The SDTORK SD-3000 + LTU Series electric actuator is specifically engineered for linear actuation applications, providing reliable and precise remote control of globe valves, gate valves, dosing pumps, and rotary valves with lever mechanisms.
Integrated with a Linear Transmission Unit (LTU), this series delivers enhanced thrust capability, accurate linear motion control, and stable mechanical performance for heavy-duty industrial applications.
Designed for both on-off and regulating duties, the SD-3000 + LTU Series ensures consistent thrust output, operational reliability, and long service life even under demanding process conditions.
Its compact, balanced construction minimizes pipeline stress while ensuring smooth, vibration-free operation — making it ideal for critical infrastructure and continuous industrial processes.
