The TRICENTRIC Seal

Various disc seals are available for different temperature and service applications for TRICENTRIC valves.  Solid metal seals are often used for temperatures above 950F and up to 1500F.  Most frequently used is the laminated stainless steel seal, which consists of thin stainless metal laminations with an intermediate gasket material (Grafoil or Klingersil C4401 are used for lamination).  The laminated seal is secured to the disc with a bolt-on steel clamp ring, and is easily accessible for replacement if required.  The Grafoil-laminated seal stack is suitable for temperatures from -40F to 1200F depending upon the application.  Klingersil C4401-laminated seal stacks are also available when required by the application.

The ultimate benefit of the TRICENTRIC seal is its bi-directional tight shut-off design.  The TRICENTRIC seal leakage meets or exceeds ANSI FCI-70-2-1991, API 598 or API 6D standards.

Under some severe and extreme conditions involving foreign matter in the line, the seal stack may become damaged, yet will still exhibit a very good sealing result.  Unlike rubber-seated valves, any damage to the seal would not tend to worsen or cause the valve to fail completely.  Any minor leakage problems can be rectified during the next scheduled shutdown by simply replacing the seal stack.  From a maintenance standpoint, the cost of unscheduled shutdowns can be drastically reduced.

These features coupled with the unique sealing system allow for use of the TRICENTRIC valve in many varied applications
