Fisher EZ Sliding-Stem Control Valve
EZ single-port control valves have unbalanced valve plugs and post-guided trim for viscous or other hard-to-handle applications with process temperatures up to 593°C (1100°F). They are available in sizes ranging from NPS ½ to 4 and pressure ratings up to CL600.
These valves utilize a clamped trim design, meaning that the seat ring and seat ring retainer are clamped into the body using compression from the valve bonnet. These valves provide up to Class V shutoff. For tighter shutoff applications, shutoff can be improved to Class VI.
Features:
-
Compliance with the Clean Air Act—ENVIRO-SEAL™ packing systems provide an improved stem seal to help prevent the loss of process fluid. The ENVIRO-SEAL packing systems feature PTFE, Graphite ULF, or Duplex packing with live loading for reduced packing maintenance.
-
Valve Plug Stability— Post guiding provides valve plug stability with a lower 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.
-
Application Flexibility—Low-flow requirements can be met 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.
-
Performance+ Seat Ring—Flow-straightening, vaned seat rings are 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. It is recommended that the Performance+ seat ring be used for non-viscous, flow-up, liquid applications.
-
More Flow Capacity for Initial Investment— Streamlined flow passages provide excellent capacities and flow.
-
Compliance with European Standards— Valves are available with dimensions specified by EN/DIN standards.
-
Sour Service Capability—Materials are available to meet NACE standards.
-
Operating Economy— Increased wear resistance provided by standard, hardened stainless steel trim means long service life.
-
Maintenance Economy— Trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts. During removal of trim parts, the valve body can stay in the pipeline.
