The GD Quick Opening Rotalock™ has been developed to provide an inherently safe, low cost solution for small diameter, low pressure applications.
Innovative Design Features
While our Bandlock™ 2 is the benchmark design for global high-
Designed and priced to offer a superior alternative to screwed closures and blind flanges, Rotalock™ handles lower pressures to ANSI 300 and diameters from 6” to 14”. It provides quick and frequent access to a range of vessels in petrochemical, pharmaceutical and chemical process technologies, at temperatures from -
Field Weldable Hubs
The Rotalock™ Closure Hub is SA350-
The fully molded lip seal is available in Nitrile (NBR) and fluorelastomer material (Viton). It is located in the cap to prevent operational damage. The use of a lip design prevents metal-
The PWS with its integral locking pin is unscrewed and completely removed. This enables the cap to be partially rotated which separates the seal surfaces giving the operator a secondary warning if pressure is still present in the vessel. A further turn of the cap allows it to be withdrawn from the hub and swung fully clear using the hinge or davit. The whole operation can be carried out by one person without the need for special tools or wrenches. Total closing of the cap is also guaranteed since the locking mechanism must be fully engaged before the integral pin is relocated and this enables the PWS to be finally screwed into its seating.
Manufactured in cast carbon steel SA352-
All of our standard horizontal closures have jib arms which allow the cap to swing to either side after opening to give greater installation flexibility. Vertical opening uses a screwed davit to lift the cap clear of the hub.
The Rotalock™ Closure is designed in accordance with ASME VIII Div. 1. ASME Code Stamp with U-
Rotalock™ Closures can be hydrotested as an option.
