Figure 1. Reverse Acting easy-eR with Actuator
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.
