Fisher control valve ET & EAT & ETR

Fisher ED control valve

Fisher easy-e™ ET, EAT, and ETR general-purpose control valves are used for throttling or on-off control of a wide variety of liquids and gases. All three valve designs have single ports, balanced valve plugs, and cage guiding. Metal-to-PTFE seating for stringent shutoff requirements is standard in all valves except those with Cavitrol™ III cages. Metal-to-metal seating for higher temperatures is standard for valves with Cavitrol III cages and optional for all other valves. The temperature limits of ET valves can be extended above 232°C (450°F) by using PEEK anti-extrusion rings in combination with a spring-loaded PTFE seal.

(a) Valve body sizes DIN: DN25 through DN200 mm.
Valve body sizes ANSI: NPS 1" through 8" inch.
EWT DIN: 100 x 50 up to 600 x 500".
EWT ANSI: 4 x 2" up to 24 x 20".
(b) Pressure Classes DIN: PN 10, 16, 25, 40, 63, 100 Bar.
ANSI: CL 150,  300, 600 # lbs.
(c) End connections: Screwed NPT internal, flat or raised-face flanged, ring-type joint, socket-weld and buttweld ends.
(d) Shutoff class (IEC 60534-4 and ANSI/FCI 70-2): IV standard with metal seat, V or VI optional with soft or metal seat.
(e) ENVIRO-SEAL packing systems designed to help prevent the loss of process fluid are available.
(f) Long-Lasting Shutoff Capability with PTFE Seating.
(g) Valve Plug Stability - Rugged cage guiding provides increased valve plug stability.
(h) Cost-Effective Operation - Increased wear resistance and dimensional standardization. Balanced valve plug construction permits use of smaller, lower-cost Fisher actuators.
(i) Maintenance Economy - The valve body can stay in the pipeline during removal of trim parts.
(j) Sour Service Capability (NACE).​
