Anti-tamper lock
December 1st 2004

By ensuring valves and actuators are only operated by authorised individuals, a new Anti-Tamper Lock (ATL) from Smith Flow Control secures a companys assets by reducing the risk of human error or deliberate tampering.

The standard condition of the device in service is locked (key-free), with the handwheel free-rotating. A coded key from the control authority is inserted, engaging the drive. The valve is then operated to the desired position before the key is removed and the valve locked in position.

The company says that, as the lock base adapter is machined to suit host equipment (this can be done on site or supplied ready machined), the ATL significantly reduces costs.
