Valve leak detector (VLD) –

The electronically controlled valve leak detector VLD is an independent unit designed for in-line installation in a chain conveyor. This VLD is fully automatic and equipped with a pressure sensor leak test head.

The test head performs a leak test (identifies the actual leak rate) on the cylinder valve. The test result is compared to a preset permitted maximum leak rate according to applicable norm/legislation. This comparison decides whether the cylinder can be approved or rejected. The leak test is only possible if the cylinder contains gas.

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 with the pressure sensor
• Maximum torque settings prevent over-tightening of screw valves Maximum torque settings sort-out cylinders with over-tightened or Jammed screw valves for correction
