Bandlock^TM 2 high pressure quick-opening closure Integral Safety Devices Safety has been engineered into the Bandlock™ 2 at every stage of its design and manufacture. A hand-operated pressure warning screw integrated into the mechanism prevents the door being unlocked until it is confirmed that the vessel’s internal pressure has been relieved. Additional secondary safety features, such as mechanical key interlocks, can be fitted and integrated with control valve operations. 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. Unique Seal To give a completely pressure-tight seal, the purpose-designed servo acting lip seal energises at zero pressure. It is housed in the door face away from the working area for protection and long life, and is easily fitted without tools. The one-piece moulding is available in a range of elastomers and incorporates a stainless steel spring to prevent extrusion and provide a full vacuum capability. Door Hinging For horizontal use the door is double pivoted on hinges with self-lubricating bearings. The bolted fitment allows adjustment for wear and can be specified for right or left swing. Vertical installation includes a davit which enables the Bandlock™ 2 door to be lifted and swung clear of the hub. At diameters over 30″, lifting eyebolts are normally fitted instead of the davit, so that the door can be lifted out of the way.
