Key Features of Fep Lined Ball Valve

• Offers Teflon/PFA Lining directly moulded on all surfaces having contact with the fluid.
• The thickness of the lining is calculated to ensure total protection against highly corrosive chemicals for long service life.
• Unlike conventional Ball Valves the ball assembly consists of one solid piece without any looseness so that there is no deterioration of lining in the area of Ball Stem Selding.
• The thickness of the lining is absolutely constant throughout to avoid any deformation of the ball.
• This is a two piece valve body construction and for special safety precaution the body end fits deeply into the other part of valves.
• This specially patented spherical design of the valve body and the body end reduces cavity volume in areas around the ball.
• Thus minimising retention within this areas to reduce product contamination problems.
• Ball valve offers a substantially lower torque than equivalent size of plug valve resulting in easy manual quarter turn operation.
• Comes with a straight cylindrical part and is neither oval nor rectangular; the port section is round, thus ensuring a flow of fluid without any turbulence. The larger port section and high CV Value permit important savings in the construction of piping units.
• The gland packing is fully made from PTFE Chevron Rings and is incorporated with springs which keeps continuous pressure on the rings thereby the sealing is absolute.
• The valve is designed to withstand temperatures from - 45 degree C to + 220 degree C and is specially lined with an anti-adhesive, self lubricating material with excellent resistance to abrasion and shocks.
