Fisher® easy-e™ EZ
Body Content 1
easy-e™ EZ valves are used for throttling or on-off control of a wide variety of liquids and gases. The single-port, globe-style body design offers quick-change trim and a post-guided, unbalanced valve plug. The EZ valve is used in chemical or hydrocarbon processing applications or wherever control of non-lubricating, viscous, or other hard-to-handle fluids is required. Metal-to-metal seating is standard for all general applications over a wide range of pressure drops and temperatures. Metal-to-PTFE seating is optional for stringent shutoff requirements.

Features and Benefits Tab
Trim Designed for Stability—
Post guiding provides valve plug stability with less chance of a sticking valve plug due to non-lubricating or sticky process fluids or build-up of entrained solids. Post guiding stabilizes the valve plug at all points in its travel range to reduce vibration, mechanical noise, and trim wear.
Performance+ Seat Ring—
Flow-straightening, vaned seat ring is available in full port and first reduction port sizes. It offers excellent open- and closed-loop performance and may be used as a direct replacement for the non-vaned seat ring. The Fisher valve division recommends that the Performance+ seat ring be used for non-viscous, flow-up, liquid applications.
Compliance with the Clean Air Act—
ENVIRO-SEAL packing systems that provide an improved stem seal to help prevent the loss of process fluid are available. These packing systems feature PTFE, Graphite ULF, or duplex packing with live-loading for reduced packing maintenance.
The process fluid flows through the trim, flushing away solid deposits above and below the guide bushing, thus reducing the possibility of a sticking valve plug.
Quick-change trim, with a clamped-in seat ring, reduces the disassembly time. The valve body can stay in the pipeline during removal of trim parts for inspection or maintenance.
Low-flow requirements can be satisfied with standard restricted-capacity trim or with Micro-Form, Micro-Flute, or Micro-Flow valve plugs. If flow requirements change, the valve can be converted to full-sized trim.
Streamlined flow passages provide greater capacities than most globe valves of the same line size.
Compliance with European Standards—
Valves are available with dimensions specified by EN/DIN standards.
Sour Service Capability—
Unless otherwise noted, references are to NACE MR0175-2002. Optional materials are available to meet NACE MR0103 and NACE MR0175 / ISO 15156. Material requirements under these standards vary by edition and year of issue; the specific standard must be specified.
