Newest Type Hydraulic Valve for Control Ball Valve
Application:
The PTK/PTM series actuators are designed for continuous multi-turn operation and can be directly connected to valves such as gate valves and globe valves. With a maximum output torque of up to 3,500 Nm, these actuators are ideal for industrial control systems where precision and reliability are essential.
Advantages:
The PT/PTJ series offers a range of advanced mechanical and protective features that make it suitable for even the most demanding environments. Here are some of its key benefits:
- Compact Design: Utilizes advanced manufacturing technology and high-quality imported components to ensure durability and performance.
- Non-Intrusive Operation: Allows for debugging and parameter setting without opening the electric box cover.
- Double Sealing & Protection: Offers IP68 protection (waterproof and dustproof), making it suitable for harsh environments.
- Explosion-Proof Grade: Can reach Ex d IIC T6, ensuring safety in potentially hazardous areas.
- Flexible Connection Options: Supports both plug and sunflower disk connections for customer convenience.
- Durable Housing: Cast aluminum housing with powder coating is ideal for extreme conditions. Ductile iron is used for high-torque models.
- Long-Lasting Gears: Hardened alloy steel worm and bronze worm gear provide long-lasting performance and support.
- Removable Stem Nut: High-strength bronze stem nut allows for easy machining to match valve stems.
- Manual Override: Features a declutch lever for manual operation, automatically disengaging when the motor is active.
- Multiple Mounting Options: Designed to fit various valve types and stem configurations.
- Corrosion Resistance: Three-layer paint system ensures protection in corrosive environments.
- Maintenance-Free Lubrication: Uses high and low temperature resistant lubricants for long-term performance.
Protection Features of PT/PTJ Series:
These actuators are equipped with multiple safety mechanisms to ensure reliable operation, including torque protection, valve limit protection, auto-phase correction, instantaneous reversal protection, phase loss protection, motor start-up time protection, motor thermal protection, electrical isolation, jammed valve discharge, and power-down data protection.
