Why New York contractors choose ValveAtlas check valves

UL 312 and FM 1210 dual listing for FDNY acceptance. Every UNIVAL check valve is UL 312 Listed (check valves for fire-protection service) and FM Class 1210 Approved. FDNY accepts listed check valves with factory submittal, NYC BC Chapter 9 compliance letter and NFPA 13 Section 16.8 sprinkler water supply documentation.

Silent-closure non-slam for fire pump discharge. NFPA 20 Chapter 4.16 requires listed check valve on fire pump discharge. UVC-NR silent-closure design uses spring-assisted center-guided disc to close before flow reversal, eliminating water hammer, pipe shock and column separation damage that plagues swing check valves on pump shutdown. Critical for New York fire pump rooms with long discharge runs.

Swing check for sprinkler incoming main. UVC-SW-4F through UVC-SW-10F flanged swing check valves with bronze or stainless disc, ductile iron body and renewable resilient seat. UL 312 Listed for sprinkler water supply, standpipe isolation check and hose valve riser check per NFPA 13 Section 16.8.

Spring-loaded wafer for compact installation. UVC-WAFER-4 through UVC-WAFER-8 wafer-body spring-loaded check valves installed between ANSI Class 125/250 flanges with no external bolting. Ideal for New York mechanical rooms with limited space between pump discharge flange and downstream gate valve.

Double-disc for low-headloss high-flow. UVC-DBL-4 through UVC-DBL-10 double-disc (duo-check) wafer valves with spring-loaded twin discs provide lowest headloss and fastest closure for high-flow fire pump discharge service. UL 312 Listed and FM Class 1210 Approved equivalent to APCO CVS-6000 and Val-Matic Dual Disc.

Ductile iron body with fusion-bonded epoxy. UVC 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 wet pipe service. Stainless steel spring and shaft, EPDM or buna-N resilient seat and bronze seating surface rated for 175 psi / 250 psi / 300 psi working pressure.

Direct substitution for Mueller, Clow, Kennedy, M&H and AVK. UNIVAL UVC-NR, UVC-SW and UVC-WAFER are UL 312/FM 1210 listed equivalent to Mueller A-2061 and A-2062, Clow F-1100, Kennedy 1500, M&H Style 259 and AVK Series 53/35. FDNY accepts listed equivalent substitutions with engineer-of-record approval and factory submittal package.

Code and listing acceptance for New York

NYC Building Code Chapter 9 (2022 edition). NYC Building Code Chapter 9 (2022 edition) references NFPA 13 and FDNY Technical Manual 2, NFPA 13 Section 16.8, NFPA 20 Chapter 4.16 for fire sprinkler and fire pump check valves. Check valve selection must satisfy Section 903.3.5 sprinkler water supply and Section 913 fire pump installation. UVC UNIVAL ships NYC BC Chapter 9 compliant.

NFPA 13 Section 16.8 sprinkler water supply check. NFPA 13 Section 16.8 requires listed check valve on sprinkler water supply connection to prevent backflow into public water main. UVC-SW and UVC-NR series satisfy this requirement. Section 16.8.2 specifies check valve plus listed indicating control valve configuration.

NFPA 20 Chapter 4.16 fire pump discharge. NFPA 20 Chapter 4.16 requires listed check valve on fire pump discharge between pump and discharge gate valve. Silent-closure non-slam check preferred for water hammer control. UVC-NR-4F through UVC-NR-10F satisfy NFPA 20 discharge check valve requirement in all New York fire pump room installations.

Backflow prevention for potable water protection. Where sprinkler system connects to potable water main, double check valve assembly or reduced-pressure zone (RPZ) backflow preventer required per local water authority. UVC check valve series provides base check valve; RPZ/DCVA assemblies available as separate line item.

FDNY acceptance. FDNY (Fire Department City of New York) and NYC Department of Buildings inspection references NYC Building Code Chapter 9 (2022 edition), FDNY Technical Manual 2, NFPA 13 Section 16.8, NFPA 20 Chapter 4.16 and manufacturer listing. Factory submittal with UL/FM/ULC certificates, functional test per NFPA 25 Chapter 13 and hydrostatic test per AWWA C508 required for sign-off.

Frequently asked questions (New York)

Is UNIVAL accepted by FDNY? Yes. UNIVAL check valves are UL 312 Listed and FM 1210 Approved. FDNY accepts listed check valves with factory submittal, NYC BC Chapter 9 compliance letter and NFPA 13 Section 16.8 documentation.

Silent-closure vs swing check on fire pump discharge? NFPA 20 accepts both listed silent-closure and swing check on fire pump discharge. Silent-closure UVC-NR eliminates slam and water hammer on pump trip; swing check UVC-SW is lower cost and preferred on low-velocity sprinkler incoming mains. For New York fire pump rooms with long discharge piping or variable-speed drive (VSD), silent-closure is strongly recommended.

What causes check valve slam? Swing check valves close when flow reverses. On fast pump shutdown, flow reverses rapidly; disc slams shut, generating water hammer shock wave that can rupture piping. Silent-closure UVC-NR uses spring and center-guide to close disc before flow reverses, eliminating slam.

Do I need check valve upstream and downstream of fire pump? NFPA 20 Chapter 4.16 requires check valve on discharge side only. Suction side has listed OS&Y gate valve (UVG-OSY). Check valve on suction is not permitted; suction must be flooded with positive pressure per NFPA 20.

Spring-loaded wafer vs flanged swing check? Wafer UVC-WAFER-4 and UVC-DBL-4 install between flanges with no external bolting, ideal for tight spaces. Flanged swing UVC-SW-6F has full flange connections with standard face-to-face dimensions. Choose wafer for compact pump rooms; flanged for standard service.

What is the delivery time to New York? Stock UVC-NR-4F, UVC-NR-6F and UVC-SW-6F ship 1 to 2 weeks. UVC-WAFER and UVC-DBL wafer stock 2 to 3 weeks. UVC-NR-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 Mueller, Clow, Kennedy, M&H and AVK on a New York project? Submit substitution letter with UNIVAL UL 312/FM 1210 certificates, factory submittal drawing and NFPA 13 Section 16.8 compliance. Engineer-of-record approval follows; FDNY accepts listed equivalent substitutions.
