Critical Technical Advantages
-
Superior Post-Guiding Stability: Unlike cage-guided valves, the EZ uses rugged post-guiding. This provides exceptional valve plug stability while significantly reducing the risk of a sticking plug when handling sticky process fluids or media with high solids content.
-
Self-Flushing Trim Design: The internal geometry ensures that process fluid flows through the trim in a way that flushes away solid deposits both above and below the guide bushing. This proactive cleaning action is essential for maintaining operational reliability in “dirty” services.
-
ENVIRO-SEAL™ Emission Control: To help facilities comply with the Clean Air Act and other stringent environmental regulations, the EZ is compatible with ENVIRO-SEAL packing systems. these systems provide a superior stem seal that virtually eliminates hazardous fugitive emissions.
-
Rapid Maintenance via Quick-Change Trim: The EZ features a clamped-in seat ring and quick-change trim. This design allows for fast disassembly and component replacement, drastically reducing downtime during planned outages or emergency repairs.
-
Vaned Seat Ring Technology: For critical loops, a flow-straightening, vaned seat ring is available. This component improves both open- and closed-loop performance and can be used as a direct, drop-in replacement for the standard non-vaned seat ring.
-
High-Capacity Passages: The EZ is designed with streamlined flow passages that provide higher flow capacities ($C_v$) than many other globe valves of the same line size, allowing for more efficient piping designs.
-
Low-Flow Versatility: For specialized low-flow requirements, the EZ can be fitted with restricted-capacity trim or high-precision Micro-Form, Micro-Flute, and Micro-Flow valve plugs.
