UL 262 and FM 1120/1130 Gate Valve Listing Verification
Technical guide · Supreme Valves India · Updated 2026-10-28
Direct answer: Before ordering fire-water gates, verify the exact model, size, rating and ends in the UL Product iQ directory (UL 262 family listings) and/or the FM Approval Guide (Class 1120/1130). A generic “UL/FM” claim without matching scope is not enough for civil defence or insurer review.
Verification checklist
| Check | Why it matters |
|---|---|
| Model designation | Listing is model-specific |
| Size range | Your NPS must be inside listed sizes |
| Ends (flanged / grooved) | Separate listing scopes |
| OS&Y vs NRS | Different constructions |
| Factory location | Follow-up inspection site must match |
UL vs FM vs both
Many specs say UL/FM — meaning both marks for the same construction. LPCB and VdS appear on European/Gulf packages. Ask which marks are mandatory before quoting commercial alternatives.
RFQ attachments to demand
- Listing excerpt for model + size
- Datasheet with resilient wedge / coating callouts
- Tamper switch requirement if butterfly control valves

Frequently asked questions
Is a UL file number enough by itself?
No. Confirm the exact model, size range, pressure rating and end connection in the UL Product iQ listing. A flanged listing does not automatically cover grooved ends.
What is FM Class 1120/1130?
FM Approvals standards covering fire-service gate valves. Approved products appear in the FM Approval Guide with manufacturer, model and size scope.
What should the quotation attach?
Listing/approval reference pages for the quoted model and size, datasheet, and confirmation that the factory location matches the listing.
