UVG-NRS-6 and UVG-NRS-8-RW 6 to 12 inch non-rising stem gate valves with mechanical joint end connections for direct bury on fire service mains feeding hydrants, post indicator valves and building incoming sprinkler mains. AWWA C509 (metal-seated) and AWWA C515 (resilient-seated) compliant with UL 262, FM 1130, AWWA C509 and C515.

Ductile iron body with fusion-bonded epoxy. UVG bodies are ductile iron ASTM A536 Grade 65-45-12 with factory-applied fusion-bonded epoxy coating per AWWA C550, rated for indoor dry-sidewall mount and direct-bury underground service. Stainless steel stem, EPDM or buna-N resilient seat and bronze operating nut rated for 175 psi / 200 psi / 250 psi working pressure.

Frost-protected for -10 F New England winter. UVG-NRS buried gate valves sized for Boston metro frost line (48 inches (1.22 m) bury per Boston Water and Sewer Commission (BWSC)). Operating stem and hand wheel extension accommodate bury depth with reliable OPEN/SHUT operation through winter freeze/thaw cycles.

Tamper-supervised with UL 753 switch. UVG-TS tamper switch kit UL 753 Listed, 24 VDC, compatible with BFD-approved fire alarm control panels per NFPA 72 supervisory signal requirements. Factory-wired to OS&Y handwheel or NRS operator for BFD fire alarm acceptance.

Code and listing acceptance for Boston

780 CMR (Massachusetts State Building Code). 780 CMR (Massachusetts State Building Code) references NFPA 13, 527 CMR 1.00 and NFPA 14 for fire sprinkler and standpipe system control valves. Gate valve selection must satisfy the sprinkler water supply and standpipe isolation requirements. The UVG series ships 780 CMR compliant.

NFPA 13 sprinkler system valves. NFPA 13 governs sprinkler system control valves. Indicating-type control valves must be OS&Y, post indicator, listed butterfly or listed equivalent. UVG-OSY series satisfies this requirement. NFPA 13 also requires all control valves be supervised per NFPA 72.

NFPA 20 fire pump installation. NFPA 20 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 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.

BFD acceptance. Boston Fire Department (BFD) and MA Board of Fire Prevention Regulations inspection references 780 CMR (Massachusetts State Building Code), 527 CMR 1.00, NFPA 13, NFPA 14 and manufacturer listing. Factory submittal with UL/FM/ULC certificates, tamper supervision acceptance test per NFPA 72 and hydrostatic test per AWWA C600 required for sign-off.

Approved-equal submittals

Where a specification names a specific manufacturer, we prepare an approved-equal submittal package (listing certificates, dimensional drawings and material data) for review by the engineer of record and the authority having jurisdiction.

Frequently asked questions (Boston)

Are these gate valves accepted by BFD? Yes. Our gate valves are UL 262 Listed and FM 1120 (OS&Y) or FM 1130 (NRS) Approved. BFD accepts listed gate valves with factory submittal, 780 CMR compliance letter and NFPA 13 documentation.

Do I need OS&Y or butterfly on my sprinkler riser? Both are listed alternatives per NFPA 13. 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.
