Frequently Asked Questions
Answers to the most common questions about product selection, the quotation process and technical topics.
Products
Why are there no prices on the site?
The price of an industrial valve or expansion joint depends on size, pressure class, body material, connection type and quantity. Publishing a single list price would be misleading. Prices are therefore prepared and sent according to the technical details in your request.
Where do the values in the dimension tables come from?
All technical values on the site are extracted structurally from the company's printed catalogs. The catalog and page number are stated at the bottom of every product page. A value that cannot be read in the source is never filled in by guesswork; it is left empty and marked “Awaiting Review”.
Why do some products have no product code?
For some products the Product Catalog does not carry a printed product code. Rather than inventing one, the field is left empty and shown as “Product code pending”. It is enough to state the product name and catalog page in your request.
Can a size not shown in the catalog be manufactured?
The dimension tables show the range printed in the catalog. For requests outside that range please write to our technical team; the assessment is made project by project.
Quotations and orders
How can I request a quotation?
There are three ways: build a list with “Add to quote list” on the product pages and send it in one go, fill in the quotation form directly, or write on WhatsApp. When you press the WhatsApp button, the product code and name are added to the message automatically.
What information should I prepare for a quotation?
For the fastest response, send: nominal diameter (DN or inches), working pressure, working temperature, fluid type and connection type. These five items are enough to select the right product in most cases.
Will my quote list be lost?
No. Your quote list is tied to your browser session and is kept while you browse between pages. Before sending, you can enter the required size, quantity, pressure and temperature on each line.
Technical questions
What is the difference between DN/PN and NPS/Class?
DN/PN is the European and NPS/Class the American designation system, and they are not translations of one another. A Class is not a pressure value on its own; the permissible pressure is read from the standard's pressure-temperature table together with body material and temperature. We have an article that covers this in detail: DN/PN and NPS/Class.
Which valve type should I choose?
In short: a globe valve if you will modulate flow, a ball valve for fast and tight shut-off, a gate valve for low-resistance isolation. See this article for a detailed comparison.
What should I consider when selecting an expansion joint?
First establish the type of movement (axial, lateral, angular) and its magnitude. Not every joint accommodates every movement. Where the axial thrust will land — on the fixed support or within the unit — must also be decided together with the design.
Can I get a technical drawing or CAD file?
Dimension tables and technical drawings are published on the product pages. If you need a CAD/STEP file for a project, you can request it from the quotation form or on WhatsApp.
Site and privacy
Why is there no cookie consent banner?
Because no cookie requiring consent is used. The site uses only two strictly necessary cookies, for the session and CSRF protection; there are no advertising or tracking cookies. See the Cookie Policy for details.
Is my data shared with third parties?
No. Your form data is not sold and not shared for advertising purposes. Details are on the Privacy Notice page.
