J B Valves

Ball Valves.

Subsea Valves
with a difference.


Subsea Ball Valves developed for endurance. Our glandless subsea ball valve benefits from market leading concentricity, eliminating factors that contribute towards gauling. Like many other of our subsea valve range the subsea ball valve is designed as an individual element, modular design philosophies allow for the element to be  applied to an array of bespoke manifolds and configurations. Our base design considerations have been developed to allow for flexible product specification. 9.5mm,  20,000psi (1375 Bar) working pressure, -45 to +180 deg C, Single Isolation, Single Block and Bleed, Double Block and Bleed & custom configurations. Pressure energised multi element chevron stem seals, bring greater peace of mind.

Process Connections

JB Valves manufacture to client specifications. API, ASME, ANSI, DIN, & threaded connections can be manufactured to order.


  • 9.5mm Bore

  • JIC, NPT, BSP & Medium Pressure Ports available as standard (other connection types available upon request).

  • 3000m (10,000 ft) water depth.

  • Up to 1375 Bar (20,000) psi working pressure (dependant  on port type).

  • Non wetted threads on both bonnet and stem eliminate crevice corrosion and contamination.
  • Multiple ingress seals on stem and body-bonnet joint provide extra protection against water ingress.
  • Inconel 718 stem as standard, increases resistance to wear and galling, resulting in superior cycling endurance.

  • Available in single Block & Bleed & Double Block & Bleed Variants.

  • ROV paddle operator or Diver operated.


316, Duplex, Super Duplex, Inconel 625, Incoloy 825, Monel, 6Mo, LF2, other materials available on request.
