FISHER™ ED, EAD and EDR single-port control valves shown in figures one, two and three have balanced valve plugs, cage guiding and metal to metal seating for all general applications over a wide range of process pressure drops and temperatures. These general purpose, sliding stem valves are used for either throttling or on/off control of a wide variety of liquids and gases. The FISHER™ ED product line is available for a wide range of applications, including sulfide and chloride stress cracking environments common to the oil and gas production industries. To discuss available constructions, contact your EMERSON™ sales office and include the applicable codes and standards required for these environments.

- The ENVIRO-SEAL™ packing systems feature PTFE, graphite ULF or duplex packing with live loading for reduced packing maintenance
- Valve plug stability - rugged cage guiding provides high valve plug stability, which reduces vibration and mechanical noise
- More flow capacity for initial investment - streamlined flow passages in the ED, EAD and EDR valves provide excellent capacities and flow
- Balanced valve plug construction - balanced valve plug construction permits use of smaller, lower cost FISHER™ actuators
- Also, trim inventory costs are cut because dimensional standardization permits use of most standard easy-e trim parts
- High temperature capability with Class IV or Class V shut-off - use of multiple graphite piston rings permit Class IV shut-off up to 593 deg C (1100 deg F)
- Sour service capability - unless otherwise noted, references are to NACE MR0175-2002
- Operating economy - increased wear resistance provided by standard hardened stainless steel trim means long service life
- Maintenance economy - the valve body can stay in the pipeline during removal of trim parts
- The EDR valve also features easy valve access without removing the actuator
