Valve Mechanical Interlocks

Door Closure Lock

The PSS door closure Lock is custom designed to interlock the closure door of a pigging vessel. The door closure Lock prevents the bleed bolt from being removed and there by the closure door from being opened. Only the insertion of a dedicated key allows access to the bleed bolt and permits its removal. This key can be only released after the door is closed and the bleed bolt is back in position. The door closure Lock is suitable for every type and size of closure door.
