Many valves on site require a simple to use locking device to prevent accidental or unauthorized operation.

ATL is available in two sizes covering all valve sizes and is available in 316 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.

很多现场的阀门只需要一个简单的锁定装置，用于防止意外的或未经授权的违规操作。

ATL有两种规格，适用于所有尺寸的阀门，并可采用316不锈钢材质。对于远程无法监控或是存在高安全风险的场合，可选用加固的碳钢锁体，使其具有更强的抗破坏性。
