Series 2500 RW Tapping Valves

14"–48" Resilient Wedge NRS Tapping Valves with Flanged x Mechanical Joint Ends - Spur Gear Actuator

AMERICAN provides tapping valves for sizes 4"-48", rated at 250 psig working pressure.

The Series 2500 tapping valve is furnished in a flange x mechanical joint configuration and includes all of the standard features found on the Series 2500 gate valve. The flange is provided with an alignment ring, which is designed to fit into a recess on the AMERICAN-manufactured tapping sleeve. This fit assures a proper alignment between the sleeve and valve, which in turn ensures proper passage of the cutter during the tapping procedure.

The Series 2500 tapping valve is made of ductile iron. The opening is larger than nominal diameter to accept full-size shell cutters through 48".

The Series 2500 Ductile Iron Resilient Wedge Tapping Valve Has These Standard Features:

  • Ductile Iron Construction

  • 250 psig ANSI/AWWA pressure rating

  • Certified to NSF/ANSI/CAN 61 and NSF/ANSI/CAN 372

  • Triple O-Ring stem seals

  • Epoxy coating inside and out in accordance with ANSI/AWWA C550

  • Thrust washers and adjustable packing type stem seals

  • Lifting Devices

  • Zero leakage

  • Dual sealing body to bonnet gaskets

  • EPDM Encapsulated Ductile Iron Wedge With Polymer Guide Covers

  • Optional gearing (Standard on 30" and larger)
