Locked Open
A locked open ball valve is a ball valve that uses a locking mechanism to lock the valve into place in an open position. By using a lock, a user ensures that the valve does not close by mistake when it should be open.

Necessity
People working in the vicinity of pressure-relief devices should be protected from malfunctions. Therefore, the valve should function properly at all times. The locking function ensures that this safety objective is met because the valve cannot accidentally malfunction.

Advantages
Frequent checking of these valves is necessary to ensure they are functioning properly without closing down the entire process -- which is time-consuming and expensive. Commonly, block valves are installed locked in the open position so that they can easily be checked while the process is still running.
