Designed for high-cycle reliability in Intertherm and Miller furnaces

lifting flame or "flame rollout" due to excessive air velocity

a 440V rated capacitor is a suitable upgrade as it offers a higher insulation breakdown threshold

ensuring the rated torque is fully transferred to the valve ball

Durable steel construction maintains tension under continuous thermal cycles
