|Superior, long-lasting in-line sealing.
The inert PTFE sleeve completely surrounds the plug. The sleeve provides a large,
circumferential sealing surface from port to port. Open, closed, or rotating, the seal is
assured. No ball or gate valve can match this sealing power.
The PTFE sleeve has a low
coefficient of friction. It acts as a lubricant. Ease of operation is assured, even when
the valve is left open or closed for extended periods.
||Secure sealing with no cold-flow deformation, blow-out, or rotation of
The sleeve is securely nestled in the body. High pressure ribs, top and bottom retention,
and 360?port lips all assure sleeve containment.
No seizing. No
As the plug rotates, the 360?lips provide a self-cleaning action to remove scaling and
No cavities. No contamination.
There are no body cavities where flow media can accumulate and contaminate subsiquant
processing. The cavity-free design also prevents sticking.
|In the most demanding
processing applications, when Tufline valves are installed downtime and maintenance are
often dramatically reduced. Service life is greatly increased. Many processors experience
substantial cost reductions when they switch from ball and gate valves.
||Ease of adjustment.
There's a fully adjustable in-line seal and dual stem seal. Bolts in the top cover provide
quick and easy adjustment. Adjust out in-line leakage between shutdowns. Adjust out
potential stem leakage. No ball or gate valve offers this capability.
Unmatched stem sealing.
There are two independent environmental seals. You get double seal protection at no extra
cost. The Tufline standard dual stem seal is clearly superior to those of gate valves,
ball valves, other plug valves, and many expensive valves with extended auxiliary packing.
Stem Seal 1.
The primary stem seal is around the circumference of the plug. Flow media is prevented
from reaching the stem.
Stem Seal 2.
The secondary backup seal system provides a wide comprehensive backup seal along the top
edge of the plug and the stem.
