Frequently Asked Questions
When should I use a gate valve instead of a ball valve?
Gate valves are preferred for large-diameter isolation (DN50 and above) where full-bore, unobstructed flow is critical and the valve will remain either fully open or fully closed — they are not designed for throttling. Ball valves are better for frequent operation and smaller sizes. In UAE building services, gate valves are common on mains water risers and fire-fighting systems.
What is the difference between rising-stem and non-rising-stem gate valves?
A rising-stem (OS&Y) gate valve provides a visual open/closed indication — the stem rises as the valve opens, requiring headroom above. A non-rising-stem (NRS) gate valve keeps the thread inside the body, staying compact — preferred in underground, valve-vault, or confined installations. Check the product spec for stem type.
Are these gate valves approved for potable water in the UAE?
MT gate valves carry CE marking, PED compliance, and WRAS / DVGW potable-water approvals. Body material and sealing elastomers are rated for drinking-water contact, meeting DEWA and Dubai Municipality requirements for water infrastructure projects.
What pressure rating do I need for UAE mains and building water?
PN10 covers the majority of UAE municipal distribution and building networks. For fire-fighting systems (10–20 bar) and high-rise risers, PN16 or PN25 is recommended. Always confirm your system design pressure and apply the appropriate pressure class with the required safety factor.
What are delivery lead times from Dubai stock?
