A primary consideration in the selection of high performance valves is the ability to provide tight shutoff.  Because of their unique design, Score-TRICENTRIC® valves are able to cover a broad range of applications in nearly every industry.  Built for services that demand performance in the chemical processing, petroleum, pulp and paper, refinery, steel and utility industries, the  Score-TRICENTRIC® valve combines performance and dependability.  As a precision machined valve, it is able to provide positive shutoff in vacuum services and pressures to 1440 psi (100 bar).  The patented sealing system has been the subject of extensive testing under carefully controlled conditions in our testing lab and at independent labs.
