Becker* Digital Natural Gas Positioner (DNGP)

The DNGP Series is used with pneumatically actuated natural gas control valves to provide an accurate valve stem position signal that is proportional to the electronic command input signal received from an electronic controller. The DNGP is compatible with all Becker actuators and may be retrofit to other manufacturer's control valve packages as well. The DNGP eliminates the need for an I/P transducer and features zero bleed consumption at steady state.

Application
The DNGP provides accurate control valve positioning with zero steady state bleed gas. Additionally, the DNGP accepts an electronic input signal direct without the need for an I/P transducer. With its simple menu setup and flexible configurations, it's the ideal control valve positioner for today's natural regulation facilities.
