SUPERSEAL INDUSTRIAL BALL VALVES 2.4

PFA/FEP LINED BALL VALVE RFFL SERIES

The Superseal RFFL lined ball valve utilises PFA lining which has the same chemical inertness as PTFE. Due to its chemical composition, PFA retains a high amount of mechanical strength at elevated temperatures. Up to 200°C (400°F).

The Superseal Model RFFL Energised Flexible Seat gives the ball a light loaded cushioning effect in all positions. The line pressure against the floating ball further energises the seat. Therefore the higher the pressure the tighter the seal, whilst at low pressures the valve is easier to turn than brands.

The inherent lubricity properties of the PTFE seat give the Ball a cushioning effect and this combined with coated Ball & integral stem ensures no jamming or stem breakage. The resilient cushioning effect also extends the life of the valve. Traditional 2 piece ball & stem design, with ‘Flat’ teflon seats place more strain on all components. In larger sizes a trunnion mounted ball is also available to further ensure no stem or seat leakage, caused by the operator forcing the ball off axis due to particulates jamming the seating area.

MATERIALS

LEGEND

L = Face to Face

N# = Number of Holes

OD = Flange Diameter

HS = Size of Hole

TH = Flange Thickness

W = Lever Length

FR = Raised Face Diameter

G = Gear Length

T = Raised Face Thickness

C = Centre of Flange to Height of Body

PCD = Pitch Circle Diameter

TORQUE

Start- Break - Away Torque

Running - 60% of B.A.T.

Close - - 80% of B.A.T.

When the ball rotates into closed position, the minute gap between the body and the seat further energises the seat against the ball, ensuring the ball and stem are not tilted on an angle (which can cause seat & stem leakage) giving the ball a trunnion like effect during closing and once closed.
