Code and listing acceptance for Boston
780 CMR (Massachusetts State Building Code) Chapter 9. 780 CMR (Massachusetts State Building Code) Chapter 9 references NFPA 13 and 527 CMR 1.00, NFPA 13 Chapter 16, NFPA 14 Chapter 6 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 780 CMR Ch 9 compliant.
NFPA 13 Chapter 16 sprinkler system valves. NFPA 13 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 Boston high-rise residential, commercial and mixed-use standpipe installations.

Frequently asked questions (Boston)
Is UNIVAL accepted by BFD? Yes. UNIVAL gate valves are UL 262 Listed and FM 1120 Approved. BFD accepts listed gate valves with factory submittal, 780 CMR Ch 9 compliance letter and NFPA 13 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. Boston 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 Boston 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 Boston? 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 Kennedy, Clow, Mueller, M&H and AVK on a Boston project? Submit substitution letter with UNIVAL UL 262/FM 1120 certificates, factory submittal drawing and NFPA 13 Chapter 16 compliance. Engineer-of-record approval follows; BFD accepts listed equivalent substitutions.
