7. SPECIAL REQUIREMENTS & REMARKS

  1. AWWA C509 Compliance

    • Valve design, materials, and testing fully comply with AWWA C509 standard for water supply service .

    • Suitable for NPS 3″ through 12″ sizes with 200 psig working pressure .

  2. Resilient Seated Design

    • Gate is fully encapsulated with EPDM/NBR rubber using injection molding process .

    • No exposed metal on gate – ensures 100% bubble-tight shut-off.

    • Rubber bonded to ductile iron – no delamination, long service life.

  3. Non-Rising Stem (NRS)

    • Stem does not rise when valve opens/closes.

    • Suitable for buried service or limited space installations.

    • Stem threads isolated from line media – no corrosion or fouling.

  4. Flat Bottom Design

    • Valve body has no recess or groove at bottom – flat design prevents debris accumulation .

    • Self-cleaning action during operation.

  5. Anti-Corrosion Coating

    • Fusion Bonded Epoxy (FBE) coating inside and out per AWWA C550 .

    • Certified for potable water (NSF/ANSI 61).

    • Color: Blue (RAL 5012) / Black / Custom.

  6. Blowout-Proof Stem

    • Stem retained by shoulder inside body.

    • Triple O-ring sealing – no external leakage, low operating torque .

  7. Zero Leakage Performance

    • Resilient seat design ensures tight shut-off even with debris.

    • Bidirectional sealing capability.

  8. Optional Features

    • UL/FM Approved for fire protection service .

    • T-Key operation for buried service.

    • Extension spindle for deep burial.

    • Position indicator / opening limiter.

    • Gear operator for larger sizes.
