PASVE pH Mounting &
Service Valve
PASVE pH is a mounting/service valve for pH sensors. It can be used with
practically all pH sensors in this size category.
PASVE pH allows the
cleaning and calibration of pH sensors without stopping the process. When
required, this can be done automatically. To protect the sensor in abrasive
processes, it can be turned to the measuring position only for the duration of
the actual measurement
PASVE pH is available in a manually operated type
or equipped with a pneumatic or electric actuator.
