Valve Chain Locks

valve chain lock

Backflow Preventer Valve Systems need to be protected with a simple padlock and chain to safeguard against vandalism and tampering.

The chain is passed around the rim of the valve wheel and secured against a fixed anchor point. You can also pass the chain around the wheel rim of an adjacent valve.

For longevity of service we recommend stainless steel chain. It doesn't need to be painted and won't go rusty; even in marine environments.

For robust security we recommend America's finest padlock, Master Lock Pro-series.

This padlock is available keyed different or keyed alike.
