VLO-NVL206 is an anti-tamper device designed to prevent unauthorized operation of instrumentation valves.

It is designed to protect needle valves from unauthorized or accidental use. It’s unique free spinning design ensures that valves cannot be tampered with or damaged when the device is locked.

It is made from Glass Filled Nylon with a radial pin tumbler locking mechanism. It is tolerant to the worst environmental conditions including salt mist spray and extreme dusty environments. Unlike other devices VLO-NVL206 can be keyed alike so that multiple valves can be secured with the convenience of having only one key.
