The Masoneilan 4700E family uses a precision feedback cam and can be applied to both rotary and reciprocating actuators. The positioner supports different control characteristics, including linear, split-range linear, and equal percentage characteristics.

For customers looking for Original New Masoneilan valve positioners, we can provide model confirmation, quotation, availability, technical documentation, and delivery support.

Product Overview

The Masoneilan 4700E series is an electropneumatic valve positioner designed to accurately control the position of pneumatic control valves.

Its precision feedback mechanism provides fast and stable response between the electrical control signal and valve travel. The positioner can be configured for different actuator arrangements and control characteristics, making it suitable for a wide range of process control applications.

The 4700E/4800E family is manufactured by Masoneilan, a Baker Hughes business.

Important: The exact actuator mounting, signal range, action, and configuration should be confirmed from the complete nameplate or part number before ordering.

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. The cam can provide linear, split-range linear, and equal percentage control characteristics.

Rotary and Reciprocating Actuators

The 4700E family can be used with rotary or reciprocating actuators. For rotary applications, the cam is mounted directly on the actuator shaft; for reciprocating applications, valve stem movement is transferred through a lever and turnbuckle assembly.

Corrosion-Resistant Construction

Internal components are manufactured using corrosion-resistant materials, providing protection for demanding industrial environments.

Enclosed Adjustment Mechanism

The adjustment components are enclosed to provide additional protection against the surrounding environment.

Easy Maintenance

The pilot valve is the only moving component in the pilot housing and can be removed without completely disassembling the positioner.

Technical Specifications

The manufacturer's documentation specifies a maximum air supply pressure of 700 kPa (100 psi) for the 4700E/4800E installation instructions, while the actual allowable pressure must be checked against the product nameplate and configuration.

4700E Input Signal Options

For example, technical documentation identifies a 4–20 mA signal configuration for the 4700E. Exact ordering information should always be confirmed from the complete product code.

Applications

Oil and Gas

Suitable for control valve applications in refineries, pipelines, gas processing, and oil and gas production facilities.

Chemical and Petrochemical

Used for flow, pressure, temperature, and process control applications.

Power Generation

Suitable for pneumatic control valves used in steam, water, and auxiliary systems.

General Process Automation

Applicable to industrial control valves requiring reliable electropneumatic positioning.
