Bulletin 51.1:ES
January 2001
Design ES and EAS Sliding-Stem Control Valves Design ES and EAS general-purpose control valves (figures 1 through 3) are used for throttling or on-off control of a wide variety of liquids and gases. Both valve designs have single ports, unbalanced valve plugs, and cage guiding. In both designs, 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 more stringent shutoff requirements.
The easy-er Valve Family Design ES and EAS valves are part of the versatile easy-e family of industrial control valves from Fisher. easy-e valves share the following characteristics: D Multiple trim material choices D Trim temperature capability with standard metal seats to 427_C (800_F) D FGM gaskets D Interchangeable, restricted-capacity trims and full-flow trims to match variable process flow demands D Trim part interchangeability that permits reconfiguring the valve to a different design variation D Different cage/plug styles that provide particular flow characteristics for highly-specialized applications. The standard cage comes in three different flow characteristics: W2174–1/IL

D Compliance with the Clean Air Act— Patented ENVIRO-SEALR packing systems (figure 5) provide a superior stem seal to prevent the loss of valuable or hazardous process fluid. The ENVIRO-SEAL packing systems feature PTFE, graphite, or duplex packing with live-loading for reduced packing maintenance. D Stable Control at High Pressure Drops— Rugged cage guiding stabilizes the valve plug at all points in its travel range to reduce vibration, mechanical noise, and the need for hydraulic snubbers. D Economy— Streamlined flow passages provide greater capacities per initial investment. When compared to globe valves of the same line size by other manufacturers, the Design ES and EAS provide more flow. D Cost-Effective Operation— Increased wear resistance of the standard hardened stainless steel trim means longer-lasting service. Also, trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts. D Easy Maintenance— The valve can stay in the pipeline during removal of trim parts for inspection or maintenance. D Longer-Lasting Shutoff Capability with PTFE Seating— Controlled compression of optional seat construction protects PTFE disk between metal disk seat and disk retainer (figure 2). The flowstream contacts only the edge of the disk during normal operation. D Compliance with European Standards—Valves are available with dimensions specified by EN/DIN standards. See figure 10 and the note in figure 11. D Sour Gas Service Capability—Trim and bolting materials are available for applications handling sour fluids and gases. These constructions comply with the recommendations of the National Association of Corrosion Engineers (NACE) standard, MR0175. Because of the care exercised by Fisher in procurement and manufacturing, additional testing and documentation to assure compliance with the NACE standard is not required, in most cases.
ENVIRO-SEAL, HIGH-SEALt Packing Systems The ENVIRO-SEAL and HIGH-SEAL packing systems from Fisher offer exceptional sealing capabilities.

These systems easily install in your existing valves or can be purchased with new valves. These systems help you seal your process to conserve valuable process fluid and to protect the environment against the emission of toxic or polluting fluids. The longer-life and reliability of these systems also reduce your maintenance cost and downtime. For applications requiring compliance with environmental protection regulations, Fisher offers the unique ENVIRO-SEAL packing system (figure 5) and, for toxic or lethal service, the ENVIRO-SEAL bellows seal bonnet (figure 6). The patented emission control packing system or seal bonnet keeps emission concentrations below the EPA 500 ppm requirement. For a superior stem seal in applications that are not environmentally-sensitive, Fisher offers the

HIGH-SEAL graphite packing system. The HIGH-SEAL packing system provides superior sealing at pressure/temperature ratings beyond ENVIRO-SEAL limits. ENVIRO-SEAL packing systems, available with PTFE, graphite, or duplex packing, and the HIGH-SEAL graphite packing system feature live-loading and unique packing-ring arrangements for longer-term, consistent sealing performance.
Class VI Shutoff Capabilities Design ES valves with metal seat constructions can provide ANSI/FCI Class VI shutoff capabilities. See tables 1 and 2.

NACE Standard MR0175 Compliance Standard procurement procedures and manufacturing processes used by Fisher assure that control valves with sour service trims comply with the chemical and physical requirements of NACE standard MR0175. Incoming raw materials are selected for sour service trims by specifications covering chemical composition, forming, hardness, heat treatment, and finish. In addition, the subsequent machining, welding, and heat treatment of the materials being processed into finished parts is strictly regulated by manufacturing standards. Due to strict start-to-finish manufacturing quality management, Fisher offers a high degree of confidence that the parts and assemblies provided for sour service comply with MR0175. Additional testing and documentation to assure compliance with MR0175 is unnecessary, in most cases. However, in cases where documentation is required, the following items can be provided: D hardness test data D certificate of compliance to specification D heat treatment documentation D chemical and physical test data The requirements of the NACE standard are very specific and the application of the standard to control
valve materials is quite complex. There are, however, some general guidelines that are always followed: D All carbon steel valve bodies and bonnets are heat-treated to 22 HRC maximum and are post-weld heat-treated. D Martensitic and cast precipitation hardening stainless steel are not used. D Control valve packing sets are jam style only. D Valve stems are made from S20910 (Nitronic 50). D Primary trim materials are S31600 and alloy 6. D Flat sheet gaskets are standard graphite/S31600 (316 SST), spiral wound gaskets are standard Inconel 600/graphite D No machining operations that cause work hardening of the materials are performed in the manufacturing process. D Plating and coatings are used only over suitable base metals and are not intended for corrosion protection. D Bolting in NACE MR0175 (non-exposed bolting) material is provided as standard. Bolting in NACE MR0175 (exposed bolting) material is available as an option. See table 11.

1. DIN (or other) ratings and end connections can usually be supplied; consult your Fisher sales office. 2. The pressure/temperature limits in this bulletin, and any applicable standard limitations should not be exceeded. 3. 316 stainless steel (CF8M) valves with SA-193-B7 bolting are capable of the full Class 600 rating through 427_C (800_F). For higher temperatures or for other bolting materials, the valve may have to be derated. Contact your Fisher sales office for further information. It should be noted that the ASME standard does not allow the use of intermediate ratings for flanged valves.
