On-site verification & testing of PV valves
Simplifying comprehensive verification cycles into streamlined workflow. Experience safer, faster and more cost-effective PV valve testing with the Ventiq innovative on-site testing node.
Simplified testing of PV valves without dismantling/reassembly
The Ventiq PV Valve Test Node is an advanced on‑site testing solution that modernizes verification of pressure/vacuum relief valves on vessels carrying liquid cargoes and emerging sustainable fuels. By enabling accurate onboard testing, it removes the need for valve removal and workshop calibration. The system provides precise measurement data to confirm set points and compliance, improving maintenance decisions and reducing malfunction risk. Streamlined testing cuts downtime, boosts crew efficiency, and strengthens the reliability of critical safety equipment for safer, smarter operations.
Cargo operation mode - (before gas freeing)
The Ventiq PV valve test node works as an insertable module between the PV valve and the cargo tank vent pipe.
It does not affect flow or operational performance during cargo mode. It is available in various dimensions and can include transition flanges for proper integration.
PV valve isolation mode - (after gas freeing)
After gas‑free status is confirmed and prior to initiating the test sequence, a portable inflatable plug is inserted into the open test node and pressurized to its designated expansion pressure. This creates a temporary isolation barrier, separating the cargo tank and vent‑pipe system from the terminating PV valve to ensure a controlled and safe test environment. It is important to note that the PV Test Node cover cannot be closed while the plug is installed, providing a built‑in safeguard that prevents accidental system re‑sealing or incorrect test configuration
Ready for test & verification
Once the system setup is complete, the test sequence is initiated. Using the Ventiq PV Valve Test Console, the opening and closing pressures are verified against the certified set‑point values on the PV valve identification tag. By regulating the compressed‑air supply pressure and selecting the appropriate flow path, the operator can execute over‑pressure and under‑pressure set‑point verification, individually or in combination, depending on the test protocol. In addition, an on‑site leakage assessment can be performed to determine whether the PV valve remains within the allowable leakage thresholds defined by applicable class and industry standards. This enables confirmation of valve integrity without removal from the installation.
