Key Features
Electropneumatic Control
The 4700E uses an electrical input signal to provide pneumatic control of the actuator, making it suitable for conventional process control systems.
Precision Feedback Cam
The positioner uses a precision feedback cam to provide accurate valve positioning and fast response, with linear, split-range linear, and equal percentage characteristics.
Rotary and Reciprocating Actuators
The 4700E family can be used with rotary or reciprocating actuators through direct cam mounting or a lever and turnbuckle assembly.
Corrosion-Resistant Construction
Internal components are manufactured using corrosion-resistant materials for demanding industrial environments.
Easy Maintenance
The pilot valve is the only moving component in the pilot housing and can be removed without completely disassembling the positioner.
