Marine Globe valves and angle valves are found wide applications generally in flow regulation duties and also applicable to duties under high temperature pressure. Globe valves are designed to be useful in rtions of piping and angle valves in bent portions.

Marine Gate valves are not suited for flow regulation duties, generally, they are used either being fully opened or closed, having smaller resistance against fluid and smaller space between flange faces than that of globe valves, HY Gate Valves are suited for applications in piping in narrower spaces. Especially, those of larger aperture contribute to economy, however, gate valves of inside screw type are not suited for duties under high temperature and high pressure according to their construction.

Check valves are designed to be installed in positions where counterflow must be prevented. Their use varies in screw-down check valves, lift check valves and swing check valves. screw-down check valves are used in positions where only counterflow check is required and can be regrouped into globe valves and angle valves.

Lift check valves are used in positions where only counterflow check is required and again can be regrouped in globe valves and angle valves.

Swing check valves are used in positions where it is required that the valves are opened and closed by small difference in pressure and that the resistance against fluid is small when it passes through the valves. Swing check valves, however, are not suited for duties under high temperature and high pressure according to their construction.

Cocks are used in positions where quick opening and closing of passage or switching of flow direction is required. Especially for switching flow direction, threeway cocks are useful. cocks, however, are not suited for duties under high temperature and high pressure according to their construction.
