Control valve
For demanding throttling control applications, the Characterized Seat Control Valve (CPT) from Worcester Controls accommodates high-pressure drops: 500 psi for liquids and 300 psi for steam. High rangeability is dictated by the shape of the characterized seat and offers controllable flow through 95% of travel. The CPT is compact and is about 30% lighter than globe valve assemblies.

Butterfly valve
Butterfly valves from Tufline feature an efficient valve lining that protects the body, disc, shaft, and all sealing components. Because the PFA lining is less porous than PTFE linings, it provides better corrosion resistance. It also facilitates better in-line sealing. In addition, the valves' continuous disc/shaft lining and body lining extend well beyond the secondary seal area. Tufline Valves
