NOV closures are customizable to any size to suit a customer’s specific requirements, and they protect assets, products, and people from adverse environmental situations and physical harm. A tried and rigorous quality control process is followed at NOV’s state-of-the-art closures facility, to ensure that customers receive reliable and quality products.
As part of NOV’s culture of continuous improvement, its closures have regularly evolved to meet customer and industry needs.
The company has evolved from Sentry I to Sentry II closures. The Sentry II uses o-rings instead of lip seals; an easier design to install and replace in the field. As NOV’s line of closures has grown, so too have opportunities for engineering advancements.
Naturally, the evolution of closures and the development of new features have resulted in a host of solutions to customer issues.
An interlocking device holds the seal of NOV Sentry closures. NOV also offers its internally developed Y2000 closure. It is also threadless, with outer clamps over the hub, preventing the door from reopening under pressure. All NOV closures have pressure alert valves (PAVs) installed. Before a customer can open the closure, they must remove the PAV. Once this is done, the door can be opened safely.
Always striving to remain innovative, NOV has continued to lead the market into the future. Input from customers will be important to future 3D closure models.
Also new to NOV closures are QR codes. These will place added information at the fingertips of customers, who will be able to read the codes with their devices, giving them access to catalogs, brochures, and drawings.
NOV’s people possess vast experience, deep product knowledge, and a passion for excellence. These, coupled with the loyalty and the partnership of customers, have resulted in the one millionth closure sale.
