R epl a ce a b le S e a t / S e a l S y ste m Tri Lok Series valves feature independent field replacement of both the seat and the seal ring. Should service conditions change, seat and seal ring materials may be substituted, without replacing the entire valve. Maintenance, downtime and costs are substantially reduced extending the overall service life of the valve. Tri Lok’s non-rubbing metal-to-metal seal delivers zero leakage with a minimal amount of torque and is inherently firesafe. The standard seat and seal ring material is stainless steel with other materials including Stellite® overlays...

Non-Rubbing Thru Rotation No contact prior to seating P ri n ciple Resilient Seal Ring Contact only once seated T R I P L E O F F S E t g eo m etr y The stem is offset on both the X (1) and Y (2) axis of the valve's centerline. This produces a cam‑like motion. The third offset (3) consists of an inclined conical profile machined into the valve sealing surface. This allows rotary engagement and disengagement of the seat and seal ring without interference. All rubbing between seat and seal ring is thereby eliminated. Once the seat and seal ring are fully engaged, torque is applied in order to create...

Design & Model FEA (Finite Element Analysis) Desi g n Bray's research and development team utilizes the latest technology to design every component for optimal performance through its full pressure/ temperature range. A n a ly z e Electronic prototypes are subjected to dimension verification as well as pressure and temperature simulations (FEA) in an effort to confirm the design and expose potential weakness in a “virtual” environment. This process ensures the actual product is “fit for purpose” prior to manufacture. V a li d a te Individual materials and assemblies are subjected to a rigorous...

T R I P L E O F F S E T T ec h n olo g y A P P L I C A T I O N S Compared to gate, globe or ball valves of the same size and pressure class, Tri Lok provides space and weight savings while minimizing installation and maintenance costs. Tri Lok is a premier isolation valve, well suited for operation in vacuum to high pressure as well as cryogenic to high temperature applications. The standard, non-rubbing, metal‑to‑metal sealing system is inherently firesafe. Applications requiring absolute zero leakage are ideally suited for triple offset technology. 24" Cryogenic ASME 150 ISO Flanged- Stainless...

M a teri a ls of C o n str u ctio n Valve bodies and discs are available in WCB Carbon Steel and CF8M Stainless Steel as standard. Low temperature Carbon Steel, Duplex Stainless Steel, Monel, Hastelloy® and NiAB are also available. The discs primary function is to "carry" the seal ring. As such, the disc material is commonly the same material as the body to allow full pressure/temperature rating and maintain uniform thermal expansion at elevated temperature. Standard stem materials are 17‑4PH, 410 Stainless Steel and XM-19 (Nitronic®). Seat, seal ring and remaining trim are selected to meet the...
