The FCO750 with custom firmware for pressure relief valve testing provides a comprehensive system for testing across a wide range of pressures, the full functionality of a valve. This can include leak testing at nominal pressure-“n%”, opening point by means of the Ramp test and re-seat point. Tolerances either side of the nominal pressure are derived from programmable limits set according to the application and these are applied to all three of the test phases.

The Barcode input system allows the instrument to select appropriate programs direct from works orders or specific build sheets with the nominal working pressure extracted from the Barcode ID. 

The test for leak integrity is typically carried out at the minimal valve pressure – a programmable tolerance to ensure the valve is closed and does not leak.

The test for nominal pressure can be either a single shot test for pre-set valves or a continuous test where the operator can adjust the tension to arrive at the nominal pressure which is then confirmed by the operator based on the displayed value.

The test for –re-seat is again derived from the nominal value and uses the programmable limits to determine that the valve has re-closed with limits.

The flexible platform of the FCO750 allows multiple tests to be defined and this in turn provides the opportunity to optimise tests according to physical size and characteristics of individual valve designs and constructions.
