Wye series electric valve actuator is a new generation of products developed independently by our company based on the original mature products, which improves and perfects the structure, optimizes the protection performance and key components. It has the advantages of compact structure, small size, beautiful appearance, stable and reliable performance. The good protection level can meet the needs of various designs: explosion-proof integral on-off type, integral modulating type.
Wye series products are used to control the opening and closing of valves. It is suitable for gate valves, globe valves, shut-off valves, diaphragm valves, and its derivative products can be used for ball valves, butterfly valves and dampers, etc. It can accurately act according to the control instructions and is an indispensable driving device for the valve to realize remote control, centralized control and automatic control.
FEATURES OF ELECTRIC ACTUATORS
This series electric valve actuator has the following features:
• Compact and robust construction, lightweight.
• Wide range of torque variation (Multi-turn: 100-3500Nm).
• Hard anodized aluminum housing inside and outside with external high temperature paint coating for use against severe industrial environment.
• Enclosure uses radial seals & O-rings that provide protection to waterproof IP67 and optional watertight lP68.
• lSO5211 standard.
• It automatically identifies and corrects phases. Automatic phase failure protection protects equipment safety.
• Reliable mechanical torque sensing system providing safe operation in overload condition.
• Large size window and indicator provides better position indication from a distance.
• Number of local position control options to provide easy commissioning and field operation.

PRODUCT STRUCTURE
1. Terminal box
The independent sealed terminal box ensures the sealing integrity of the electrical part of the electric actuator when performing on-site wiring, and meets the product explosion-proof requirements.
2. Sealed structure
The actuator adopts a double-sealed design structure to ensure that the actuator is completely waterproof and dustproof; the standard product protection grade is IP67, and the highest grade can reach IP68.
3. Power transmission
The power transmission of the actuator uses a precision reduction mechanism consisting of a bronze alloy worm gear and an alloy steel worm. The worm gear and worm run separately in grease, which is suitable for the maximum ambient temperature difference and maximizes the service life.
4. Output interface
The actuator flange complies with ISO5210/5211 (GB12222/12223) standards, and also provides flange interfaces that comply with JB2920 standards, and it can be specially customized according to customer requirements.
5. Shell anti-corrosion
The outer surface of the actuator is painted with a special aluminum alloy paint with a tough paint film and strong adhesion. It has strong UV resistance, corrosion resistance and high fullness, which can comprehensively improve the service life and self-cleaning properties of the coating and is suitable for various harsh production environments.
6. Motor
The motor adopts low inertia and high torque motor, which can quickly reach the peak torque after the motor starts, and there is almost no over-limit movement when not excited; there is a precise temperature sensor in the motor, and the over-temperature limit is set through the control system to avoid damage caused by overheating of the motor.
7. LCD interface
The LCD interface can display text information, graphical elements and actuator characteristics.
8. Selection of control mode
The selective switch “Remote”-“Stop”-“Local”installed on the local operating device can be used to set up remote operation (remote control) or local operation (local control) or stop mode. 9. Local electric operation The operating switch “Open”-“Close” installed on the local operating device can be used to open or close actuator locally.
