Fisher easy-e ED Universal Globe Valvesare part of the sliding stem valve rangethat have balanced plugs and cage-guided trim for all general applications with process temperatures up to 593°C (1100°F).
The easy-e ED valves are available in sizes ranging from NPS 1 to 30 and pressure ratings up to CL600, with several globe body, sliding-stem configurations, including ED, EAD, and EDR:
Fisher easy-e ED product range is available for a wide range of applications, including sulphide and chloride stress-cracking environments common to the oil and gas production industries.
1. EN (or other) ratings and end connections can usually be supplied; consult your Emerson Process Management sales office. 2. The pressure/temperature limits in this bulletin and in any applicable standard limitations should not be exceeded
