High quality Rotary Electric Actuator with Ball Valve Butterfly Valve Gate Valve for Environmental Protection
High Quality Rotary Electric Actuator with Ball Valve, Butterfly Valve, and Gate Valve for Environmental Protection
Application:
The PTK/PTM series electric actuators are designed for continuous multi-turn operation and can be directly connected to various types of valves such as gate valves and globe valves. These actuators are ideal for industrial automation systems where precise control is required. The maximum output torque reaches up to 3500 N·m, making them suitable for heavy-duty applications.
Advantages:
PT/PTJ Series Mechanical Features:
1. Compact design with advanced manufacturing technology and high-quality imported components.
2. Non-intrusive design allows for debugging and parameter adjustment without opening the electrical box.
3. Double-seal and double-protection structure ensures complete waterproofing and dustproofing, with an IP68 rating (3 meters for 48 hours).
4. Explosion-proof grade can reach Ex d IIC T6, suitable for hazardous environments.
5. Terminal connection options include plug or sunflower disk connections for customer flexibility.
6. Cast aluminum housing with powder coating for extreme conditions. Optional coatings available. Ductile iron used in large torque boxes for durability.
7. Long-life gear set made from hardened alloy steel worm and bronze worm gear, fully supported by bearings.
8. Removable high-strength bronze stem nut for customization to fit different valve stems.
9. Manual override lever enables manual operation; automatically disengages when motor is powered on and can be locked in place.
10. Multiple mounting configurations available for different valves and stems.
11. Three-layer paint system for corrosion resistance in harsh environments.
12. Maintenance-free lubricant suitable for both high and low temperatures.
