1 SJ-N MODEL SJ-N BUTTERFLY VALVE The Model SJ-N Butterfly Valve is a grooved-end tight shut-off valve designed, manufactured and tested to MSS SP-67. The valve can be shipped either with a -position lever handle with a lockg device (SJ-N-L) or with a worm gear operator (SJ-N-W). The valve consists of epoxy powder coated ductile iron body and EPDM or Nitrile (NBR) rubber encapsulated dual-seal disc. The Model SJ-N is rated up to + 0 F (+93 C) for general service use and is UL classified accordance with NSF/ANSI 61 and NSF/ANSI 372 for potable water service up to temperature +1 F (+82 C).

Upper & Lower Shafts: Staless steel Type 4. Stem Seals: O-Rg, EPDM. Lever Handle: Ductile Iron to ASTM A536, Gr and or to ASTM A395 Gr Black pated. General Notes: Maximum Workg (CWP) listed is the maximum cold water pressure for general pipg services tested to ASTM F1476 and or AWWA C606 methods. Figures listed are based on roll- or cut-grooved standard wall carbon steel pipe. For other pipe schedules or pipe materials, contact Shurjot for additional formation. Listed and or Approved s are pressure ratgs for fire protection systems, tested and approved by various approval bodies. Please always refer to the latest approval data posted on the Shurjot website. Field Jot Test: For one time only the system may be tested hydrostatically at 1½ times the maximum workg pressure listed (AWWA C ). Warng: Pipg systems must always be depressurized and draed before attemptg disassembly and or removal of any components. The Year Limited Warranty applies to manufacturg defects only and does not cover severe service/temperature applications or wear parts. Shurjot reserves the right to change specifications, designs and or standard without notice and without currg any obligations. -6/6 Rev. AH 17
