Lined Plug Valves

PFA/FEP Lining offers highest corrosion resistance. Minimum lining thickness of 3mm, lining locked in dove tail grooves, slots and Holes in the body & plug castings. This prevents Liner collapse in vacuum conditions and blow out in high pressure conditions.
Lined Plug Valves have Body of Ductile Iron as per ASTM A 395 Gr-60-40-18 with Plug Made up of ASTM A 351 Gr CF8.
