H664R - 2-way globe valve, PN6 flange, DN 65, kvs 58 Housing and seat gray cast iron GG25

•   Stem/bypass-seat stainless steel
•   Seal EPDM O-ring
•   Temperature of medium max. 120°C
•   Characteristic A-AB equal percentage
•   Leakage rate A-AB max. 0.05% of kvs


  • 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.
