The electronically controlled valve seal tester VST (for centre valves only) is an independent unit designed for in-line installation in a chain conveyor.
The VST is fully automatic. The test head simulates the end-user regulator, so the unit performs a tightness test of the regulator connection to the cylinder valve (the situation when the cylinder is in use at the end-user).
The tightness test identifies any valve/seal defects with MAKEEN Energy’s unique pressure test head and pressure sensor. A leak rate will result in a pressure change. The pressure sensor detects small changes of pressure (rise or drop) in the test head. This change is compared to a preset permitted maximum pressure change. This comparison decides whether the cylinder can be approved or rejected. The pressure test is possible even if the cylinder does not contains gas.
The unit is compatible with MAKEEN Energy's Industry 4.0 Digital Solution, which enables data capturing of the process for remote supervision, performance optimisation, and predictive/preventive maintenance alerts through e.g. a MAKEEN Energy cloud solution (optional).
