MASONEILAN POSITIONER

Description

GE’s Masoneilan 4700P is a user friendly pneumatic Positioner that uses a precision feedback cam for accurate positioning, faster response, and customized control characteristics for control valves. These positioners can be used with either rotary or reciprocating actuators. The 4700P offers a multi-lobe cam, simple zero and span adjustments, corrosion resistant materials, fully enclosed and with FM, CSA, ATEX approvals. Mounting kits are available as standard for GE Masoneilan control valves as well as adaption for other control valve designs.

The Masoneilan Model 4700 control valve positioners offer flexibility and consistency with modular design construction and corrosion resistant packaging. They can be configured either as a standard pneumatic valve positioner or as an electro-pneumatic device by simply assembling the separate I/P transducer module to the base pneumatic valve positioner. These instruments are for either reciprocating or rotary type valves, and are available in optional configurations for hazardous area applications.

• • Flexibility to use with either reciprocating or rotary control valves assists in optimizing process control performance through customizable cam characterization.
  • Optional high capacity pneumatic bloc 4800 model for accurate positioning and fast response times on large size actuators.
  • Rugged turnbuckle and lever assembly couples stem motion to the cam when mounting reciprocating actuators.
  • Modular design construction makes it a simple and easy-to-maintain device, also easy to assemble, calibrate, and operate in many control applications.
  • Configurable for direct or reverse operation utilizing the same mounting orientation.
