Brass, also known as copper and zinc alloy, the most commonly known is the March 7 brass, which is the ratio of zinc and copper. Because of its good mechanical properties and processability is widely consumed. Brass globe valves are widely used on marine valves. With the ordinary valve does not have the advantages. Shut-off valve is the closure of the valve (valve) moves along the valve seat center line. Depending on the type of movement of the valve disc, the change in valve seat opening is in direct proportion to the valve disc stroke. Due to the valve stem of this type of valve opening or closing stroke is relatively short, but also has a very reliable cut-off function, but also because the valve seat opening changes in proportion with the valve stroke is proportional to the flow rate is very suitable for regulation. Therefore, this type of valve is ideally suited for shut-off or regulation as well as throttling.

Advantage:
(l) During the opening and closing process, it is wear-resistant because the friction between the valve disc and the sealing surface of the valve body is smaller than that of the valve.
(2) The opening height is generally only l / 4 of the diameter of the valve seat passageway and is therefore much smaller than the gate valve.
(3) Usually there is only one sealing surface on the valve body and the valve flap, so the manufacturing technology is relatively good and easy to maintain. However, the shortcomings of the globe valve can not be ignored. The main drawback is the large flow resistance coefficient, resulting in pressure loss, especially in hydraulic devices, this pressure loss is particularly evident.

Globe valve stem opening or closing stroke is relatively short, but also has a reliable cut-off function, while changes in valve seat opening and valve stroke is proportional to the relationship between the flow for the regulation. Therefore, this type of valve is ideally suited for shut-off or regulation as well as throttling.
