Needle Valves.

Subsea Valves
with a difference.

Description

Subsea Valves with a difference. Our unique glandless subsea needle valve benefits from market leading concentricity, eliminating factors that contribute towards gauling.  The very core of our subsea needle valve range starts with individual elements, designed to be modular and applied to an array of bespoke manifolds and configurations. Our base design considerations have been developed to allow for flexible product specification. Full bore ports, up to 13mm,  20,000psi (1375 Bar) working pressure, -45 to +180 deg C, Single Isolation, Single Block and Bleed, Double Block and Bleed & custom configurations. Glandless bonnet utilises pressure energised multi element chevron stem seals, thus eliminating the requirement for routine adjustment.  Cartridge style head unit allows quick change out, reducing maintenance down time.

Process Connections

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