Newest Type Hydraulic Valve for Control Ball Valve
Application:
The PTK/PTM series electric actuators are designed for continuous multi-turn operation and can be directly connected to valves such as gate valves, globe valves, ball valves, and butterfly valves. These actuators deliver a maximum output torque of up to 3500 N·m, making them ideal for industrial control systems requiring precision and durability.
Advantages:
The PT/PTJ series actuators offer a range of advanced features that ensure reliable performance in demanding environments. Key advantages include:
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 full waterproof and dustproof protection, with an IP68 rating (3 meters for 48 hours).
4. Explosion-proof grade can reach Ex d IIC T6 for safe use in hazardous areas.
5. Flexible terminal connection options: plug-in or sunflower disk style.
6. Durable cast aluminum housing with powder coating, suitable for extreme conditions. Optional coatings available.
7. Long-life gear set made from hardened alloy steel worm and bronze worm gear, fully bearing-supported.
8. Removable high-strength bronze stem nut for customization to match different valve stems.
9. Manual override lever enables manual operation and automatic disengagement when the motor is on.
10. Multiple mounting types available for various valve configurations.
11. Three-layer paint system for enhanced corrosion resistance in harsh environments.
12. Maintenance-free lubricant for both high and low temperature applications.
