Introduction
Scope of Manual
This instruction manual includes installation,
maintenance, and parts information for 1- through
4-inch Design EDR and ETR valves (see figure 1).
The valves are available in Class 150 through 600
ratings.
The valves are also available with full-size and
restricted-trim designs. Refer to separate manuals
for instructions covering the actuator and
accessories.
No person may install, operate, or maintain a Design
EDR or ETR valve without first D being fully trained
and qualified in valve, actuator, and accessory
installation, operation, and maintenance, and D

Description
The Design EDR and ETR are single-port,
globe-style valves that feature cage guiding, a
balanced plug design, and push-down-to-open valve
plug action. The valve constructions are available
with metal-to-metal or metal-to-composition seats.
These constructions permit access to the internal
trim parts through the bottom flange without
removing the actuator from the valve.
