Instrumentation, Masoneilan Model 4700P / 4700E Analog Valve Positioner
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.
