Grooved Check Valves London: UL Listed, ULC Certified and FM Approved Grooved-End Swing and Silent Wafer Check Valves for NFPA 13 Sprinkler, NFPA 14 Standpipe and NFPA 20 Fire Pump Discharge Applications
ValveAtlas supplies UL Listed, ULC Certified and FM Approved grooved-end swing check (UVSC-G310) and silent wafer check (UVSC-W310) valves in DN50 through DN300 (2″ through 12″) with ductile iron body and EPDM-encapsulated disc or bronze disc with EPDM seat to fire protection contractors and mechanical subs across London. 300 psi working pressure. Full NFPA 13/14/20 compliance and London Fire Brigade (LFB) acceptance under Approved Document B and BS 9990.
Technical reference for London sprinkler contractors and fire pump installers working on airport terminals, high-rise towers, financial-district office buildings and university campuses. Grooved swing check is the preferred backflow prevention at fire pump discharge, sprinkler riser base and standpipe inlet. Silent check (spring-assisted wafer) eliminates water hammer in long horizontal sprinkler mains and fire pump discharge piping.
UVSC-G product range for London projects
UVSC-G310 is the grooved swing check with ductile iron body (ASTM A536), EPDM-encapsulated bronze disc and 300 psi rating. UVSC-W310 is the silent (spring-assisted wafer) check in matching sizes for water hammer-prone installations. UVSC-F310 is the flanged swing check (not grooved) for legacy flanged riser retrofit. All three carry UL + ULC + FM listing (threaded UVSC-T310 has UL + FM only).
Why London contractors choose ValveAtlas grooved check valves
UL 312 and FM 1210 triple listing. UVSC-G310 carries UL 312 (Check Valves for Fire Protection Service), FM 1210 (Swing Check Valves) and ANSI/CAN/UL/ULC 312 Canadian equivalent listings.
EPDM-encapsulated disc for bubble-tight shutoff. Bronze disc substrate with EPDM encapsulation provides bubble-tight backflow prevention and corrosion resistance for wet sprinkler and standpipe service.
Silent (spring-loaded wafer) variant eliminates water hammer. UVSC-W310 closes before reverse flow develops, preventing the pressure surge that causes pipe rupture at fire pump startup/shutdown.
