FISHER TYPE EZR
Technical Parameters
Category Parameter Specification / Description
General Model Series EZR
Type Rotary Control Valve
Shaft Motion Rotary
Pressure & Temperature Pressure Rating (ANSI) ANSI Class 150, 300, 600
Max. Allowable Pressure Up to 1480 psig (102 bar) for Class 600.
Temperature Range Standard: -50°F to 800°F (-46°C to 427°C). Depends on seat and seal materials.
Flow & Sizing Valve Sizes Depends on the attached rotary valve (e.g., 3" to 48" / DN80 to DN1200).
Flow Capacity (Cv) Extremely High. Determined by the specific ball, butterfly, or plug valve it is coupled with. Can range from hundreds to tens of thousands.
End Connections Flanged (RF, RTJ), Wafer, Lugged (for butterfly valves).
Actuator & Performance Mounting Designed to be paired with Fisher SC Series scotch-yoke piston actuators or other rotary actuators.
Torque Output Provided by the actuator. The EZR system is designed to transmit high torque efficiently.
Characterization Achieved through the characterized cam in the actuator positioner, providing linear or equal percentage flow characteristics.
