  • The GVL system is designed to ensure the safety of personnel in the repair or maintenance of industrial equipment.

  • The use of GVL blockers is a set of measures that allow an enterprise to exclude potentially dangerous situations related to unauthorized delivery of liquids or gases, which can lead to injury or more serious consequences

  • The procedure provides for the disconnection of the supply of liquids or gases during the repair work and the posting of warning labels or placards

  • This system has long been used successfully in foreign enterprises. The introduction of the GVL system is one of the most important stages in the complex of measures to reduce industrial injuries

Mounting on a regular rod

Mounting on the slide rod

The device consists of two identical halves, hinged together with each other with the ability to lock the device with padlocks.

1. Half of the body of the device
2. The protrusion
3. The groove
4. The semicircular element of the plug
5. The lugs
6. The holes for the hinge pin
7. The lip
8. The holes for the lock

The first and second halves of the body have corresponding mating surfaces with protrusions and grooves, and when the two halves of the body mate with each other, the protrusions enter the corresponding grooves, tightly closing the two halves of the device body and forming a closed cavity inside the device. There is a cap provided on the surface of each half of the body, removing which, you can get an hole on the body, which serves to grasp the valve stem or gate valve.

The device is mounted on the valve stem or gate valve, closing with its two halves the rotating handle of the valve or gate valve.

At the same time, the device rotates freely and does not allow the possibility of changing the position of the rotating handle of the valve or gate valve.

The locks with arch diameters no more that 8 mm with quantity from 1 to 4 are set in the lugs of the hole that we get after the connection the two halves. The removal of the device from the valve stem or gate valve is carried out in the reverse order.
