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.
Outer body graded cast iron as per ASTM Standard, other materials like cast steel / stainless steel available on request.
2 Way cavity free design prevents accumulation of particulate matter making it an ideal choice for slurry applications.
The seal from this plug valve is created by the interface of the plug & the liner. The outside of the plug and the body cavity are at a taper of 2°. The wedge action results in a tight shut-off. Because the Seal is created because of compression it is bi-directional sealing on both upstream and downstream sides.
Adjustment bolts on the top cover can be utilized for external adjustment of in-line seal.
