Pressure warning screw: A hand-operated pressure warning screw integrated onto the door arise the operator attention about the pressure inside the equipment until it is confirmed that the vessels internal pressure has been relieved.

Mechanical lock part: Door can not be opened in any way without removing mechanical locking part which is robust mechanical part between teeth.

Stepped tooth: As a result of the operation, there will be a static pressure due to the presence of liquid at a certain height. This pressure originating from the inside fluid head cannot be detected by the devices. At this point, the door teeth are designed as two-stepped for safe opening and rapid transfer of the liquid inside.

Visible lock band: For complete safety, the locking band can be seen at all times, which satisfies design code requirements and means that the operator can actually see that the door is securely closed and locked.

Mechanical key interlocking system: Mechanical key interlocks, can be fitted and integrated with door operations. Utilisng the Closure Lock, you would able to interlock the closure door of a vessel, preventing it from uncontrolled openings. This is a critically important product. When combining the Closure Lock in an interlocking sequence, you guarantee that the isolation valve and the vessel is vented and drained, before your operators can unlock and open the door.
