How to install an electric actuator on a coke oven flue damper valve?

2025-08-05

Most are likely familiar with the correct operation of coke oven flue gate valves. Let us now examine precisely how they function:

Installation of Electric Actuators: Coke oven flue gate valves are mounted on pipelines. With process adjustments, on-site operators can no longer easily manually operate these valves. Therefore, it is necessary to retrofit flue gate valves with electric actuators to meet operational requirements.

Requirements for actuators vary by location: - The actuator's torque or thrust must meet gate valve opening/closing demands, with stroke and torque protection required; - Based on position indication, the flue gate valve should enable localised opening, closing, and stopping; - Some locations mandate explosion-proof actuators.

When calculating the opening/closing torque for the gate valve, the flue gate valve's operating pressure and temperature must be considered. The actuator's output torque should be 1.2 to 1.5 times the valve's working torque. When converting a coke oven flue gate valve to an electric gate valve, a mounting bracket must be installed on the valve before the actuator can be properly fitted.
