J B Valves

Ball Needle Ball
Double Block & Bleed Valves.

Ball & Needle
Valves

Description

Ball Isolation & Needle Vent configurations within a compact single piece or bolted package. Single piece and bolted configurations can be offered in Flange by Flange or Flange by Thread configurations.

Venting needle valve can be specified as Screwed, Bolted, or OS&Y.

Monoblock multi valve isolation assemblies are designed to reduce leak paths & improve operational safety factors. Monoblock solutions are designed to replace conventional multi valve constructions. Fatigue and strain from large assemblies is reduced significantly by using close coupled manifold systems.

Process Connections

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