Valve seal tester

Automatic in-line in chain conveyor

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.

  • MAKEEN Connect

    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).

Benefits

Maximum safety level

  • Fully automatic testing of all cylinders (eliminates human errors)
  • Fully automatic leak rate testing for periodic verification of the preset leak rate (optional)
  • More accurate, reliable, and consistent detection of leaks due to test heads with narrow tolerances simulating the end-user regulator and due to pressure sensor developed with specific measuring range and very fine division

Maximum production uptime

  • Automatic predictive and preventive maintenance alerts with MAKEEN Energy’s Industry 4.0 Digital Solution to avoid breakdowns (optional)
  • Automatic operation stops (e.g. low compressed air pressure) prevent process errors and assist in quick restarting
  • Quick adjustment to different cylinder sizes and valve types

Optimised production

  • Remote supervision with MAKEEN Energy’s Industry 4.0 Digital Solution for production optimisation
