Frequently Asked Questions
What is the advantage of a 3-piece body design?
A 3-piece body allows the valve to be fully disassembled — end caps and ball can be removed inline without cutting the pipeline. This enables seat replacement, ball inspection, and in-line cleaning, significantly reducing maintenance costs in industrial service where the valve must be serviced regularly.
Why choose stainless steel AISI 316 over brass for industrial service?
AISI 316 stainless offers superior resistance to chlorides, acids, and aggressive media — essential where brass would corrode. In the UAE, SS316 threaded ball valves are specified for food and beverage, pharmaceutical, swimming-pool (chlorine), RO permeate lines, and marine applications where DZR brass would be inadequate.
What is the PN63 pressure rating?
PN63 (63 bar at 20°C) suits hydraulic circuits, compressed gas, high-pressure water injection, and industrial process lines. For standard building water (4–12 bar) and fire-fighting (up to 20 bar), PN63 provides a very substantial safety factor and margin for pressure testing.
What certifications and material documentation is available?
CE marked under PED 2014/68/EU. Material test certificates (EN 10204 3.1) for AISI 316 body, ball, and stem available on request. Manufactured under ISO 9001:2015 at MT Valves' Barcelona facility.
