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.
