Press Release Summary:
Xtreme(TM) soft-seat technology is available on Jamesbury ANSI Class 150 and 300 ball valves up to 12 in. and butterfly valves up to 24 in. It is based on flexible-lip seat design using polymer formulation, which increases wear resistance and resistance to permanent deflection. Seats also lower operating torque requirements. Permanent deflection of seat material is virtually linear from 100 to 450Â°F.

Award Winning Xtreme(TM) Seats Available on Jamesbury Valves
Vaaler Award winning seat technology provides better temperature
and pressure performance at lower operating torque.
SHREWSBURY, MA (October 8, 2002) - Xtreme(TM) advanced soft seat technology, which won CHEMICAL PROCESSING magazine's Vaaler Awards competition in 2001, is now available on Metso Automation's Jamesbury ANSI class 150 and 300 ball valves up to 12" and butterfly valves up to 24". XTREME seats expand both temperature and pressure performance, and require lower operating torque than other high-performance materials. XTREME sealing technology is being offered without an increase in price.
XTREME advanced seat technology is based on Jamesbury's proven flexible-lip seat design using a unique polymer formulation to extend the range of standard, high-performance seats into higher temperature and pressure ranges without increasing valve costs. XTREME offers greatly enhanced wear resistance and resistance to
permanent deflection, resulting in increased cycle life and reduced operating costs.
XTREME's(TM) temperature and pressure capabilities are greater than filled PTFE and equivalent to those of PEEK. Permanent deflection of the seat material is virtually linear from 100°F to 450°F, while deflection of PTFE and filled PTFE materials typically increases with temperature, inhibiting the seat's capability. In fact, as temperatures rise from ambient to almost 450°F, permanent deflection of the XTREME seat actually diminishes. At 450°F, the permanent seat deflection of the product is half that of PTFE. Chemical resistance is comparable to PTFE but with significantly greater operating life.
In addition to lower cost, the XTREME technology's major advantage over PEEK seats is dramatically lower torque requirements. As a result, some users have been able to downsize actuator packages by as much as 50%, making installation into tight spaces easier. In addition, the total cost of the valve package is reduced.
The XTREME seat is one of the most significant breakthroughs in sealing technology since Jamesbury pioneered the flexible-lip polymeric seat design in 1967. Research is currently underway to develop the next generation of cost/performance optimizing sealing materials.
