PASVE®
PASVE® pH – Mounting and Service Valve for pH Sensors
Optimize pH sensor performance and extend lifespan with safe, inline maintenance. Available in manual or pneumatic versions.
PASVE® pH is a mounting and service valve for pH sensors.
With PASVE® pH, you can:
– Enhance the performance and extend the lifespan of your pH sensors
– Ensure that your sensors stay wet or are cleaned between batches
– Measure pH only when necessary during batch operations
– Enjoy non-invasive cleaning of process sensors
– Purge process fluids easily before sensor removal
– Test and calibrate transmitters on-site
– Directly connect your calibrator to PASVE® pH
PASVE® pH is available in a manually operated type or equipped with a pneumatic actuator.
Key Features & Benefits
- Inline pH Sensor Maintenance Without Process Shutdown
Install, remove, clean, or calibrate pH sensors while the process is running — without interrupting production. - Prolong Sensor Lifespan
Keep sensors clean and wet between batches to maintain measurement accuracy and prevent premature wear. - On-Demand pH Measurement
Measure only when needed during batch processes — reducing sensor exposure and improving overall stability. - Direct Calibrator Connection
Easily connect a calibrator directly to the PASVE® pH valve for quick and accurate onsite calibration. - Safe and Easy Cleaning
Clean or flush sensors and remove residual process fluids without opening the process line. - Non-Invasive Sensor Cleaning
Enables gentle cleaning without removing the sensor, helping maintain hygienic integrity and process continuity. - Manual or Pneumatic Operation
Choose between manually operated models or versions with a pneumatic actuator for automation-ready integration.
Typical Applications
PASVE® pH is ideal for:
- Batch Processing Plants:
Control pH measurement frequency and protect sensors between cycles. - Water and Wastewater Treatment:
Maintain sensor performance in fluctuating flow or chemical conditions. - Pulp and Paper Industry:
Ensure reliable pH readings during chemical dosing and process monitoring. - Food & Beverage Production:
Maintain hygienic pH monitoring in CIP-compatible lines. - Chemical and Biotech Processes:
Perform calibration and cleaning without interrupting sensitive process flows.
Frequently Asked Questions
Can I calibrate the pH sensor without removing it?
Yes. PASVE® pH allows direct connection to a calibrator for on-site calibration without removing the sensor.
Does this valve help keep the pH sensor wet between batches?
Exactly. It protects the sensor tip from drying out between process cycles, which extends lifespan and improves reliability.
Is PASVE® pH available with automation support?
Yes. It comes in both manual and pneumatic actuator versions for integration into automated systems.
Can I flush or clean the sensor in place?
Yes. You can purge the process fluid and perform non-invasive cleaning through the valve body.
Is this valve compatible with all pH sensors?
PASVE® pH is compatible with most standard pH sensors, see available connections on our datasheet.
