Hyperbaric Closure System
How it works!

The Canty QUICKPORT is a Quick Opening access door suitable for both positive and negative pressure sealing without modification. The door is a flat stainless steel or carbon steel disk that rolls into position through a slot behind the door. The Seal ring carries two o-rings and is spring loaded to provide initial seal contact. One o-ring seals against the door and the other seals against the wall of the cylinder. The design is suitable for high pressure, low pressure, or vacuum service. The closure can be used for either internal or external service and provides safe, instant access to any vessel.


CANTY Engineering

The Rolling Door closure is the safest, quick opening closure ever designed. What makes it unique is the method for door engagement. All other types of closures have doors that swing out or slide out away from the end of the reactor barrel in the same direction that the pressure force acts. If pressure is not completely relieved the door can blow open with great force and velocity and the potential to injure personnel. The Canty Rolling Door slides out of the barrel at a direction perpendicular to the pressure force, and therefore the Canty door never retains potential energy from process pressure and can never be accelerated by residual pressure. Because the door moves perpendicular to the pressure a separate safety interlock is not required.
