How do I identify the model of a pressure relief valve with an electrical signal?

• Suitable for purchasing YSFpressure relief valve, customers who use pressure relief valves with electrical signals and safety accessories for transformers.
• Before requesting a quote, we recommend confirming the complete model number, signal suffixes (such as "K"), nominal diameter, opening pressure, and photos of the old valve.
• Electrical signal requirements relate to wiring and alarms; we do not recommend requesting quotes based solely on pipe diameter.

When purchasing pressure relief valves with electrical signals, it is necessary to confirm not only the nominal diameter but also the opening pressure, signal type, suffix, and wiring requirements. Pressure relief valves are safety accessories for oil-immersed transformers; whether replacing or selecting new ones, you should always refer to the confirmed specifications. Innotongda can assist in compiling quotation requests based on the confirmed information for the YSF series.

Confirmation of the Model Suffix for the Electrical Signal of the Pressure Relief Valve

YSF pressure relief valve suffixes include D (directional oil injection), K (electrical signal), SK/KK (dual electrical signals), J (mechanical signal), TH (humid tropical), and B (lockable device). Please provide the complete model number and suffix when placing an order.

If the nameplate on the old valve shows YSF9-70K/80K, YSF9-80K/130K, or any other designation, please take a clear photo of the nameplate. Different suffixes will result in different functions and pricing information.

Procurement Specifications for Electrical Signals for Pressure Relief Valves

Please provide the nominal diameter, opening pressure, installation connections, photos of the signal junction box, equipment model, tank installation location, and the original technical specifications. Drawings can be provided for new projects.

If you don’t have any drawings, you can start by taking photos of the entire old valve, the bottom connection, the junction box, and the installation location. We’ll use this information to determine what additional details we need.

Request for Quote on Replacement of Used Electrical Signals for Pressure Relief Valves

When replacing old components, check whether the original signal format is the same. If the original system is connected to an alarm or protection circuit, do not simply purchase a standard pressure relief valve.

If you wish to switch from a standard model to a model with electrical signals, you will need to reconfirm the wiring, contacts, and on-site safety requirements.

Discussions on Quotations from Manufacturers of Electrical Signals for Pressure Relief Valves

Manufacturers will provide quotes based on the complete model number, nominal diameter, pressure rating, signal type, quantity, and delivery date. Any special suffixes or environmental requirements must be specified separately.

Innotongda will base its communication on the nameplates, drawings, and on-site information provided by the customer to avoid using unconfirmed parameters.

Differences Between Electrical Signal Configurations and Spare Parts for Pressure Relief Valves

Project specifications focus more on drawings, order quantities, technical documentation, and delivery schedules, while spare part replacements focus more on old models, wiring, installation dimensions, and on-site compatibility. 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

To ensure that the quote more closely matches your actual procurement needs, we recommend that you clearly specify the product name, full model number, quantity, intended location of use, whether the product is a replacement for an existing item, whether English documentation is required, and your expected delivery date when making initial contact. If the product is to be used as part of a project, you may also provide drawings, technical specifications, and packaging and shipping requirements.

Innotongda will provide documentation and quotations based on the models, configurations, and technical requirements confirmed by both parties. This will reduce the need for repeated verification and minimize the risk of purchasing incompatible products.

Procurement Contacts and Responses to Inquiries

If the buyer already has photos of the used parts, they can simply send the images and quantities; if this is for a new project, they can first send the drawings, technical specifications, or a product list. We will first confirm the product details and then respond with the relevant materials, pricing, and any additional information required.

Related FAQs

1. Can I request a quote for a pressure relief valve based on a photo of the old part?

Sure. The photos can be used for a preliminary assessment, but we’ll need the model, quantity, and key dimensions to provide a formal quote.

2. Can we discuss this first even if we don’t have any drawings?

We can discuss this first. We recommend providing the nameplate information, installation location, and photos of the site.

3. Can you provide materials in English?

Once the model and configuration have been confirmed, we can provide English documentation or a quote as needed.

4. Why is it important to confirm the quantity before providing a quote?

The quantity will affect the price, delivery time, packaging, and documentation requirements.

5. How can we reduce the need for repeated communication?

When making your initial inquiry, please include the model number, photos, quantity, delivery date, and intended use—this will make communication more efficient.
