  Introduction
Many valves on site require a simple-to-use locking device to prevent accidental or unauthorised operation.
 
  Construction
ATL is available in two sizes covering all valve sizes and is available in 304 Stainless Steel. For remote unmonitored or higher security risk areas, a carbon steel, case hardened option is available, which will withstand the toughest forms of vandalism.
 
  Coding
The units can be uniquely coded or coded alike, dependant on operational conditions/ requirements.

 

  Operation
With the unit fitted to the valve, the standard SFC tamper-proof coded card key can be inserted allowing valve operation. Depending on operational requirements, the valve can be operated to any position, once the key has been removed, the unit free wheels, preventing valve operation.
 
  Ordering
The units are available "off the shelf' allowing customers to undertake the simple machining operation for fitting, thus reducing order times and offering an instant security/safety solution.
 
Many valves on site require a simple-touse locking device to prevent accidental or unauthorised operation. The ATL has been developed to fit directly to valves in place of the normal handwheel or operating lever, with little machining which can easily be undertaken by the customer.
