Fisher EZ Sliding-Stem Control Valve
 آتصا | ابزاردقیق و اتوماسیون
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.
