Description

Multi-turn IP68 Electric Actuator Overview

The multi-turn ip68 electric actuator relies on a robust mechanical system at the heart of reliable valve control. It must withstand extreme forces, variable environmental conditions, and frequent use. The BD350-C8 series, manufactured by Bonray, achieves this through superior materials and precision engineering. Our factory utilizes a lightweight yet durable aluminum alloy housing for the main body and a finely machined, hardened steel gear train. The mechanical efficiency of our transmission ensures that a smaller motor can deliver higher torque, reducing energy consumption. With a modular accessory design, we tailor each unit to the specific valve and control system, offering complete flexibility in installation.

Can I order this Multi-turn IP68 Electric Actuator with a different flange to fit an old valve?

Yes. We produce the actuators on demand. If you provide the valve flange drawings, our factory can machine the mounting flange and drive sleeve to match your existing infrastructure, saving you the cost of valve replacement.

Multi-turn IP68 Electric Actuator Features

• Ergonomic Manual Override: We designed the handwheel with a unique “pop-out” mechanism. To engage, the operator lifts the anti-misoperation pin and pushes the handwheel inward. The gear engages instantly for emergency operation. A padlock hole on the handwheel shaft prevents unauthorized manual intervention.

• Dual-Seal Technology: The housing uses O-rings for static seals and oil seals for dynamic seals (shafts). This ensures the actuator maintains its IP68 rating even after years of operation.

• Modular Terminal Board: The spring-loaded terminal blocks accept a wide range of wire gauges (0.8 to 2.5 mm²) and allow for quick, secure connections without the need for specialized tools.

Protect Function

Mechanical Over-Torque (via Software): While the multi-turn ip68 electric actuator does not use mechanical friction clutches, our software-controlled torque sensing provides a more accurate and repeatable torque limit that does not degrade over time.

• Motor Thermal Protection: The factory installs PTC thermistors or thermal switches within the motor windings. This direct contact method provides the most accurate measurement of internal motor temperature.

• Valve Seating Protection: The actuator manages the final seating of the valve. It can be set to “Torque Seat” for open and close positions, ensuring a tight seal without over-compressing the valve seat.

Control 

• Low Voltage Dry Contacts: For safe, explosion-proof control.

• High Voltage Control (AC 220V): For retrofit applications where existing control wiring uses high voltage.

• ESD (High/Low Level): Configurable for normally open or normally closed emergency loops.
