QOC Solutions offers manual quick opening closures with tooth as well as automatic. This type of QOC gets activated through the rotation of a system of teeth which allows the fast opening. The manual rotation uses a rack system, while the automatic one uses a hydraulic piston and pump system.The recommended sizes for our quick opening closures with tooth go from DN 6’’ to DN 46’’, and the specially recommended rating is the ANSI 150 one, even if the typology can be applied to rating ANSI 600.
