SENTRY® Closures

SENTRY® high pressure closures are ideal for pipeline, pressure vessel, pig trap, filter and filtration system and manway access applications. SENTRY® non-threaded, internal door closures provide many features and benefits that are not available in other types of closures. Some of these benefits include:

• Greater Security - due to heavier, more rugged locking components that retain pressure in both shear and compression modes
• Greater Safety - with all locking components fully engaged until vessel depressurization is complete
• Quicker, Easier Operation - that requires little effort from a single operator to close the largest closure with minimal time

All pressure retaining components on the SENTRY Closure are manufactured from ASME SA designated materials. The innovative pressure-energized seal provides extended service life and reduced maintenance expense. The simple profile of the sealing surface allows for easy inspection and cleaning. An improved hinge arrangement and a unique means of holding the locking segments in the open position, make operation of the Closure smooth and easy. The innovative method of securing the Closure's locking components to the door also helps to prevent the possibility of injury during pipeline or vessel servicing.
