The MT Series full-bore brass ball valves in CW617N alloy (EN 12165, PN30) are engineered for applications where zero pressure drop and unrestricted flow are critical — irrigation mains, chilled water primaries and industrial utilities across the UAE. The internal bore matches the pipe bore exactly, eliminating turbulence and reducing pumping costs. An ergonomic stainless steel handle and colour-coded grips make field operation fast and reliable. CE · ACS · WRAS certified, stocked in Dubai.

Frequently Asked Questions
What does the pressure rating PN mean, and is it enough for UAE building systems?
PN (Pressure Nominale) is the maximum working pressure in bar at 20 °C. PN25 and PN30 comfortably exceed typical UAE building water pressure (4–12 bar). For fire-fighting risers up to 20 bar and industrial circuits these ratings remain within safe limits. For higher-pressure steam or industrial applications MT offers PN40 and PN63 ranges.
Why is DZR brass specified for UAE potable-water systems?
Dubai and UAE water supplies are predominantly desalinated — low mineral content, slightly acidic, and aggressive towards standard brass. DZR (Dezincification-Resistant) brass (EN 12165 / CW602N) resists selective zinc leaching that causes standard brass to fail prematurely. DEWA and Dubai Municipality specifications require DZR brass for potable-water pipework.
Are the threads BSP or NPT? Which standard is used in the UAE?
These valves use BSP (British Standard Pipe) threads — the standard throughout the UAE, GCC countries, and most of Asia, Africa, and Europe. NPT (American) threads have a different taper angle and are not interchangeable with BSP. All MT brass ball valves are supplied with ISO 7-1 BSP threads as standard.
What certifications do MT brass ball valves carry?
MT ball valves carry CE marking, comply with PED 2014/68/EU, and are manufactured under ISO 9001:2015. The range holds DVGW (Germany), WRAS (UK) and ACS (France) potable-water approvals — internationally recognised as the highest drinking-water certification standards. Datasheets with certification dossiers are available on request.
What are delivery lead times and minimum order from Dubai stock?
Items marked "In Stock — Dubai Warehouse" ship same or next business day with no minimum order quantity. Delivery within Dubai is typically 1–2 business days; across the UAE 2–3 business days. For project volumes, MT Middle East offers scheduled releases from stock — contact us with your bill of materials for a quotation.
