* Flowgrid* Regulator


Helping the Natural Gas Industry Increase Efficiency and Performance. Baker Hughes’ Mooney Flowgrid Regulator is an easy-to-maintain valve for self-contained pilot systems that allows users to maintain pressure and flow control of almost any gas or liquid. The ability to control pressure and flow increases accuracy of use, responsiveness and stability while decreasing parts, noise levels and maintenance and energy costs. Combined with top entry access to all components, the Mooney Flowgrid Regulator adds value for customers looking to produce energy more efficiently and reliably with less expense and greater awareness of environmental responsibility. As a self-contained, pilot-operated device, the advanced technology solution can offer substantial energy savings when compared to conventional air-operated or electrically operated control valves.


  • In-line maintenance with minimal part
  • Rugged fabric-reinforced throttling element/diaphragm provides flexibility, stability and fast response time in severe service conditions
  • Elliptical main spring provides a high frequency response, proportional action for stability, consistent low minimum differential and shut-off force
  • Spring case designed to enhance speed of response and stability
  • More than 88 valve body options fit a wide variety of applications
  • Throttle plates offered in four standard capacities: 100%, 75%, 50% and 35%. Custom capacities available if desired
  • Symmetrical throttle plate design helps prevent debris from accumulating under the seat and affecting shut-off
  • Symmetrical throttle plate design helps prevent debris from accumulating under the seat and affecting shut-off
  • Equal inlet/outlet pressure rating for all sizes assures easy operation without special start-up procedures required
  • Dual-port valve design provides redundancy with dual pilots and extra capacity with one pilot
  • Compact size for easy installation in any position
