pH 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. ... PASVE® pH is available in a manually operated type or equipped with a pneumatic or electric actuator.

The service valve (PASVE) can be mounted on a pipe or on a tank. It is used to safely remove an instrument. The instrument can be a pressure transmitter (level sensor), turbidity meter, pH meter or conductivity meter.

The probe is inserted into this valve and when it is needed to be removed then the valve body rotates to isolate the instrument from the process. The rotation can be automated or manual.
