UL / FM FIRE PROTECTION PRODUCTS USP0 SERIES RESILIENT WEDGE GATE VALVE DESIGN FEATURES SECTION B-1 Rev. 7-17 Shaded area indicates change USP Series Resilient Wedge Gate Valves U.S. Pipe Valve & Hydrant Resilient Wedge Gate Valves have features to make them easier to operate and to preserve the sealing capability and interior coating integrity for many years of reliable service. 3" - 12" USP1 Series Resilient Wedge Gate Valves 6” shown ❏ 350 PSIG (2400 kPa/24 barg) Maximum Working Pressure – Hydrostatically tested at 700 psig (4800 kPa/48 barg). ❏ Dual-Purpose Lifting Lugs – new dual-purpose lifting lugs provide stability for the valve box. Accomodates strap or hooks; provides valve box alignment, eliminating need for valve box adapter.+ ❏ American Made Quality – factory in Chattanooga, TN with ISO 9001 certification. Certified to ANSI/NSF 61 & 372. Manufactured and tested in compliance with ANSI/AWWA Standard C515. UL 262 Listed and FM 1120/1130 Approved. ❏ Ductile Iron Construction - Valve body, bonnet, disc, stuffing box, & op nut. ❏ T-Head Bolt Retention – improved T-head bolt retention feature eliminates need for anti-rotation bolts. ❏ Triple O-ring Seals – two above thrust collar and one below, retain lubricant in this critical area. Top two are replaceable with valve fully open and under pressure. Fourth 0-ring serves as dirt seal. ❏ Two-Anti-Friction Washers With Lubrication – made of polymer, one above and one below the thrust collar, reduce operating torque to open or close valve. ❏ STEM – forged manganese bronze bar stock is upset, then machined to form a thrust collar for superior strength in this critical area. ❏ Guide Cap Bearings – made of polymer and snapped over rubber covered wedge guides, provide bearing surfaces that protect both wedge and interior body coating from wear and aid in easy operation – even the largest valves installed horizontally. Rollers, tracks and scrapers are not needed. ❏ Smooth, Oversized Water Way – full, round, unobstructed flow way accommodates full size cutters, provides superior flow characteristics and reduces pumping costs.** ❏ Mueller Pro-Guard® Fusion Bonded Epoxy Coating – 10 mils* thick protects all inside and outside iron surfaces, and complies with AWWA C550. ❏ 316 Stainless Steel Fasteners ❏ Integral Legs – stands upright for easier handling and storage. ❏ 10-Year Limited Warranty – assured reliability (see separate Mueller Warranty document for terms). ❏ Designed For Potable Water Applications 14" – 54" 2361 Series Resilient Wedge Gate Valve Features In addition to all the features of the smaller 2361 series valves, large size Mueller 2361 series RW valves offer these features: ❏ Stem – 18"-54" manganese bronze casting with integral thrust collar.
