Flowserve-Valbart-Trunnion Mounted Ball Valves - Subsea

Trunnion Mounted Ball Valves - Subsea

BRAND: Valbart

The Subsea Trunnion Mounted Ball Valve is a quarter-turn ball valve designed for total reliability against internal and external leaks in shallow and deep-water applications.

Product Highlights

Industries

  • General Industry

Industry Sectors

  • Other Industries

Standards

  • API 6DSS/6A
  • ASME B16.34
  • BPVC Sec. VIII

Design Range

Size Range:

  • DN 50 to 1400
  • NPS 2 to 56 (API 6DSS Valves)
  • NPS 1 13/16" to 7 1/16" (API 6A Valves)

Pressure Class Range:

  • PN 20 to 420
  • Class 150 to 2500
  • API 2000 psi to 10000 psi

Seating Material: Soft or Metal

Features and Benefits

  • Application flexibility derived from compatibility with hydraulic actuators, ROV-operated gear boxes, and electrical and hydraulic umbilical systems
  • Extended life due to robust design that protects against leaks with metal-to-metal seats, elastomeric and thermoplastic seals, and corrosion-resistant alloy seal housing
  • Minimized leak paths made possible by body designs plus corrosion-resistant materials of construction
  • Complete safety and functionality compliance ensured by hyperbaric chamber testing (API 6DSS certification/API Spec Q1)

Configurations

Shallow water

  • Side entry (bolted or welded body) or top entry construction
  • Flanged / BW / HUB ended
  • Soft & metal seated
  • Diver/ROV/Hydraulic operated
  • Elastomeric (HNBR or FKM) and thermoplastic seals (lip-seals or c-ring) to prevent internal leakage
  • Bolting cap protection

Deep water

  • Side entry (bolted or welded body) or top entry construction
  • Flanged / BW / HUB ended
  • Soft & metal seated
  • Diver/ROV/Hydraulic operated
  • Elastomeric (HNBR or FKM) and thermoplastic seals (lip-seals or c-ring) to prevent internal leakage
  • Bolting cap protection
