Product Description

Details

Features


  • Mode of operation The globe valve is operated by an NV or AV series linear actuator. The linear actuators are controlled by a standard modulating or 3-point control system and move the cone of the valve, the throttling device, to the opening position dictated by the control signal.

  • Flow characteristic An equal-percentage flow characteristic is produced by profiling the valve cone.

  • Manual operation On the NV or AV linear actuator, the valve stem can be actuated manually using a hexagonal key.
