Tufline Sleeved Plug Valves

 

Design Features & Benefits


  1. The full-circumferential resilient sleeve has a low coefficient of friction, assuring ease of operation even when the valve is left open or closed for extended periods;
  2. Inert resilient sleeve - completely surrounds the plug, assuring full sealing in open, closed, or rotating positions;
  3. The sleeve is securely nestled in the valve body. No seizing. No sticking. No cavities - no contamination.
    Secure sealing with no cold-flow, deformation, or sleeve rotation and greatly minimized potential for blow out.

 

Tufline® Sleeved Plug Valves - Design Features and Benefits

 INDUSTRIAL STANDARDS:

  • ASME Section III
  • ASME B16.10
  • ASME B16.34
  • ASME B16.5
  • ASME B16.25

 

With Tufline® Sleeved Plug valves, design more economical, flexible, and compact fluid handling systems.
Bi-directional flow, simple actuation, lightweight, compact design, and multiport configurations all facilitate improved system design.


Superior, longer-lasting in-line sealing.
The inert resilient 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.


Secure sealing with no cold-flow, deformation, or sleeve rotation and greatly minimized potential for blow out.
The sleeve is securely nestled in the valve body.
High-pressure ribs, top and bottom retention, and 360° port defining lips all assure sleeve containment.

 

No seizing. No sticking.
As the plug rotates, the 360° lips provide a self cleaning action to remove scaling and adhering media.

 

No cavities. No contamination.
There are no body cavities where flow media can accumulate and contaminate future processing.
The cavity-free design also prevents sticking.

 

Eliminate unscheduled downtime and maintenance plus get greatly extended service life.

Many processors experience dramatic cost reductions when they switch from ball and gate valves.
A simple turn of the top adjustment bolts keeps the sleeve sealing tightly and the valve in service far longer.
Two independent sealing systems provide double protection against atmosphere leakage.


Tufline® 3-Way Benefits

Trouble-free sealing is provided by the large, full-circumferential resilient sleeve. No ball or gate valve can match this sealing capacity. Sleeves are easily replaced inline.
The resilient sleeve has a low coefficient of friction. Ease of operation is assured, even when the valve is left open or closed for extended periods.
Lower cost and greatly extended service life assure exceptionally low, long-term cost-of-ownership.

 

 

The Tufline® sleeved plug valve pays for itself many times over with more up-time and greatly extended service life. 

There’s a fully adjustable in-line seal and dual stem seal.
No ball or gate valve offers this capability.

Tufline® Sleeved Plug Valves - Design Features and Unique Benefits

 

Stem Seal 1.
The primary stem seal is around the circumference of the plug.
Flow media is prevented from reaching the stem.
There are two independent environmental seals.
You get double seal protection
at no extra cost.

 


Stem Seal 2.
The secondary backup seal system provides a wide comprehensive backup seal along the top edge of
the plug and the stem.
Unmatched stem sealing.
Tufline’s 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.

 


360° lips.
Port defining lip were developed and patented by Tufline.
The lips surround the ports.
The lips improve valve performance and extend service life by:

  • Preventing sleeve cold flow and deformation.
  • Eliminating sleeve rotation.
  • Breaking up and removing adhering, scaly deposits from the outer surface of the plug as it rotates.
