• Before requesting a quote, we recommend confirming the QJ model, diameter, installation orientation, signal contacts, and photos of the old parts.
• Gas relays are protective devices; it is not recommended to purchase them based solely on appearance or pipe size.

QJ gas relays are commonly procured for the maintenance of oil-immersed transformers, replacement of spare parts, and project supply. Since their specifications depend on oil pipe connections, installation orientation, and signal contacts, it is necessary to confirm the required pipe diameter and contact specifications before requesting a quote. Innotongda can supply relevant models, including the QJ9-25, QJ3-80/50, QJ2-80/50, QJ1-80/50, and other related gas relay products.

When requesting a quote, clearly state the intended use so that suppliers can more quickly identify the key points in the documentation.

If you need both spare parts and project products, we recommend listing the quantities, delivery dates, and documentation requirements separately. We will confirm these based on their specific uses and will not apply a single model or set of specifications to all procurement requests.

Confirmation of Information and Pricing
