UB6 Duplex Steel Plug Valve Introduction | 6 Inch 150LB ANSI Corrosion Resistant Plug Valve From J-VALVES

All valve bodies, plugs and stems are integrally forged from UB6 duplex steel, eliminating casting defects like porosity. Uniform alloy composition avoids galvanic corrosion under harsh corrosive fluid, extending service life by over 300% compared with cast stainless steel valves.

Strict ANSI & API Standard Compliance

All 150LB UB6 plug valves follow ANSI B16.5 flange standard and API 6D valve specification. 6” 150LB dimensions are fully interchangeable with international famous brands, no pipeline modification needed for project replacement, saving overall engineering cost.

Bubble-Tight Bi-Directional Sealing

Composite reinforced PTFE lining provides Class VI zero leakage in both flow directions. Multi-layer anti-leakage stem packing plus anti-static design meet safety requirements for flammable oil & gas media.

Flexible Automation Actuator Matching

Standard mounting bracket with universal actuator interface (yellow indicator cap as shown in photo), easily fitted with pneumatic diaphragm actuators, explosion-proof electric actuators, limit switches and solenoid valves for DCS automatic control system.
