Building Regulations Approved Document B (ADB) 2019, BS 9990, BS 9999. Building Regulations Approved Document B (ADB) 2019, BS 9990, BS 9999 references BS EN 12845 and BS EN 12845 Section 7, LPC Rules TB203, LPCB LPS 1090 and LPS 1197 for fire sprinkler and standpipe system control valves. Gate valve selection must satisfy Section 903.3.5 sprinkler water supply and Section 905 standpipe isolation. UVG UNIVAL ships ADB and BS EN 12845 compliant.

BS EN 12845 Chapter 16 sprinkler system valves. BS EN 12845 Chapter 16 governs sprinkler system control valves. Section 16.9.3 (indicating-type valves) requires OS&Y, post indicator, listed butterfly or listed equivalent. UVG-OSY series satisfies this requirement. Section 16.9.5 requires all control valves be supervised per NFPA 72.

NFPA 20 fire pump installation. NFPA 20 Chapter 4.16 requires OS&Y gate valve on fire pump suction and discharge with listed tamper supervision. UVG-OSY-6F and UVG-OSY-8F with UVG-TS tamper switch satisfy fire pump isolation and supervision requirements.

NFPA 14 standpipe control valves. NFPA 14 Chapter 6 requires listed OS&Y or PIV isolation valves on standpipe incoming main and zone isolation. UVG-OSY-6F and UVG-OSY-8F with supervision satisfy NFPA 14 for London high-rise residential, commercial and mixed-use standpipe installations.

LFB acceptance. London Fire Brigade (LFB) and UK insurers (RSA, Aviva, Zurich, Allianz, AXA) inspection references Building Regulations Approved Document B (ADB) 2019, BS 9990, BS 9999, BS EN 12845 Section 7, LPC Rules TB203, LPCB LPS 1090 and LPS 1197 and manufacturer listing.

Frequently asked questions (London)

Is UNIVAL accepted by LFB? Yes. UNIVAL gate valves are UL 262 Listed and FM 1120 Approved. LFB accepts listed gate valves with factory submittal, ADB and BS EN 12845 compliance letter and BS EN 12845 Chapter 16 documentation.

Do I need OS&Y or butterfly on my sprinkler riser? Both are listed alternatives per NFPA 13 Section 16.9.3. OS&Y provides visual OPEN/SHUT indication via rising stem; listed grooved butterfly with integral tamper provides position indication via lever. London common practice uses OS&Y on fire pump room and main risers; grooved butterfly on zone isolation.

What working pressure do I need for high-rise standpipe? NFPA 14 requires 150 psi minimum at highest outlet with total system pressure often exceeding 250 psi in tall buildings. UVG-OSY-6F-HP 300 psi satisfies lower-zone high-rise standpipe isolation in London tall buildings.

Resilient wedge vs metal-seated? AWWA C515 resilient wedge provides tighter seal, easier operation and longer service life for buried potable/fire service applications. AWWA C509 metal-seated is legacy standard. UVG-NRS series defaults to C515 resilient wedge; C509 available on request.

What is the delivery time to London? Stock UVG-OSY-4F, UVG-OSY-6F and UVG-OSY-8F ship 1 to 2 weeks. UVG-NRS buried mains ship 2 to 3 weeks. UVG-OSY-HP 300 psi high-pressure factory-built ships 3 to 4 weeks. Metro freight from Toronto HQ 2 to 3 business days.

How do I substitute AVK, Patterson, Crane and Hattersley on a London project? Submit substitution letter with UNIVAL UL 262/FM 1120 certificates, factory submittal drawing and BS EN 12845 Chapter 16 compliance. Engineer-of-record approval follows; LFB accepts listed equivalent substitutions.
