PTFE Lined Plug Valve

Flow-Tech Valves and Engineers  PTFE Lined Plug Valve use high precision casting method for all major pressure holding components. We offer Carbon Steel (ASTM A 216 Gr. WCB) and Stainless Steel (ASTM A 351 Gr. CF8 / CF8M) body, plug and cover

Flow-Tech Valves and Engineers  PTFE Lined Plug Valve feature an unpigmented virgin PFA lining applied

by Transfer Molding and locked into castings by machined dovetail-shaped

grooves, and cast dovetail-shaped recesses in body castings and cast holes.

Locked In liner in our ptfe lined plug valve prevents liner collapse in vacuum conditions and also prevents blow out in high temperature and pressure combined conditions

By design PTFE Lined Plug Valves are cavity-free both in open and closed positions which ensures no particle accumulation and makes them Ideal for corrosive slurry applications

Salient Features of Flow-Tech Valves and Engineers  PTFE Lined Plug Valve :

Cavity Less High Performance Design

Zero Leakage (Class VI Leakage Rate) due to large sealing area

Unique Lining makes it Fully Locked from Top, Bottom & Port.

Totally Maintenance Free Design.

Ensures low pressure drop with higher flow rate
