The KW Designed Solutions threaded closure pressure vessel, utilises a two-piece closure system, which consists of a plug and captive lock ring. They are an economical alternative to our range of quick-acting closures and are generally specified for small to medium sized pressure vessels.
The closure is easy to handle, safe, reliable and robust in operation. It incorporates a unique smooth-form thread and low friction coating, that allows effortless opening / closing of the vessel, without tooling. This provides the operator with quick and easy access into the pressure vessel if required; offering many advantages over a typical bolted closure.
The threaded closure allows low cost elastomeric o-rings, back-up ring combinations or engineered plastic seals to be fitted; rather than metal to metal seals. Thus, making service and maintenance cheaper and the pressure vessel more cost-effective.
These vessels require minimal shop floor space, as they are used in vertical orientation. With the incorporation of a vessel and closure support frame, they can be supplied horizontally; ensuring closure alignment is maintained with the vessel body.
