The PSL/Q series electric actuator is a high-performance mechatronic control unit designed for industrial automation. It encompasses the PSL series for linear stroke applications (e.g., globe and cage valves) and the PSQ series for part-turn applications (e.g., ball and butterfly valves). The actuator features an integrated electronic proportional module, eliminating the need for external amplifiers as it directly receives standard 4-20mA DC or 1-5V DC signals. Its precision transmission converts motor power into accurate linear thrust or rotary torque to achieve continuous valve regulation. Renowned for its compact size, light weight, precision, and self-locking capabilities, the series is widely utilized in power, chemical, water treatment, and food processing industries.

1.Highly integrated modular design:The control circuit uses an integrated electronic structure that combines servo amplification and position feedback. This compact layout reduces external wiring and minimizes the risk of electromagnetic interference.
2.High-precision transmission and positioning:Utilizes precision reduction gears with high-strength ball screws (PSL) or worm gears (PSQ) to ensure a highly linear relationship between output and command signals. It features minimal dead zones and excellent repeatability.
3.Reliable mechanical self-locking:The transmission system possesses natural self-locking properties. During power failure or shutdowns, it firmly holds the valve position against pressure fluctuations, ensuring process safety.
4.Comprehensive intelligent protection:Features built-in electrical limit switches, torque protection, and motor thermal sensors. The system automatically cuts power and triggers alarms during stall or abnormal load events to prevent damage.
5.Manual and automatic override:Equipped with an independent manual handwheel for intervention during commissioning, power loss, or maintenance. The transition is smooth, ensuring 24/7 operational reliability under extreme conditions.
6.Durable industrial housing:The high-quality die-cast aluminum alloy casing is treated with high-performance anti-corrosion coating. Rated at IP65/IP67, it resists dust, moisture, and corrosive gases in harsh outdoor environments.
7.Wide compatibility and interchangeability:Mechanical interfaces comply with international standards, allowing for easy adaptation to various global control valve brands. This facilitates system upgrades and onsite maintenance.
8.Low maintenance cost:Core transmission parts feature long-term lubrication for low mechanical wear. The electronic module supports non-intrusive online calibration, significantly shortening maintenance cycles.
